The Best Time to Have Sex... According to Science.

Summary

This educational video explores the optimal times for consensual coitus from both anatomical and physiological perspectives. It delves into sperm production in males, highlighting that they can produce up to 300 million sperm cells daily, and testosterone levels peak in the morning, potentially enhancing sexual performance. For females, the video examines the 28-day sex cycle, emphasizing the importance of ovulation and the role of hormones like estrogen in increasing libido. The video suggests that while morning intercourse might offer benefits, the best time for conception in females is around ovulation. It concludes by encouraging individuals to experiment with different times to determine personal preferences, acknowledging the complexity of human sexual behavior beyond biological factors.

Takeaways

• 🕗 Males have a high sperm production rate, with up to 300 million sperm cells produced daily, suggesting they are potentially ready for intercourse at any time.
• 🌅 Testosterone levels in men peak in the morning, which can enhance libido and erectile function, suggesting that morning might be an optimal time for sexual performance.
• 🤝 Engaging in morning intercourse is reported to increase feelings of connection and bonding, reduce stress, and enhance happiness and productivity throughout the day.
• 🔬 The female sex cycle, or menstrual cycle, typically lasts around 28 days, with variations, and is crucial for understanding the best time for intercourse from a reproductive perspective.
• 🌡️ Follicle Stimulating Hormone (FSH) initiates the development of ovarian follicles at the start of the female cycle, leading to the maturation of one egg for potential ovulation.
• 📈 Luteinizing Hormone (LH) surges in the middle of the female cycle, triggering ovulation, which is the release of a mature egg from the ovary.
• 🥚 The egg released during ovulation is viable for only about 24 hours, emphasizing the importance of timing for conception.
• 🚫 Sperm cells, in contrast, can survive in the female reproductive tract for up to five days, which can extend the window of opportunity for fertilization.
• 🌟 The best time for reproductive intercourse from a female perspective is just before and during ovulation, considering the short lifespan of the egg and the longevity of sperm.
• 🧠 Sexual desire and the decision to engage in intercourse are complex and influenced by various factors beyond just biological readiness, including emotional connection and personal preference.

Q & A

What does the term 'consensual coitus' refer to?

Consensual coitus refers to sexual intercourse that is mutually agreed upon by all parties involved.

How many sperm cells can the human body produce in a day?

The human body can produce up to 300 million sperm cells in a day.

What is the average rate of sperm production per hour?

On average, the human body produces approximately 12.5 million sperm cells per hour.

At what time of day are testosterone levels typically highest in men?

Testosterone levels tend to be highest in men around 8 A.M.

What hormone is often referred to as 'The Love hormone' and why?

Oxytocin is often referred to as 'The Love hormone' because it is linked to connection, bonding, and feelings of pleasure and euphoria.

What are the potential benefits of having intercourse in the morning?

Potential benefits of morning intercourse include increased connection with partners, decreased stress levels, increased happiness, and improved productivity at work.

What is the female sex cycle, and what is its average duration?

The female sex cycle, also known as the menstrual cycle, is the physiological process that prepares the female body for potential fertilization and pregnancy. Its average duration is about 28 days, though it can vary from 20 to 45 days.

What is the role of follicle-stimulating hormone (FSH) in the female reproductive system?

Follicle-stimulating hormone (FSH) stimulates the development and maturation of ovarian follicles, which house the eggs, at the beginning of the female sex cycle.

What is ovulation and when does it typically occur in a 28-day cycle?

Ovulation is the release of an egg from a mature ovarian follicle, typically occurring around day 14 of a 28-day cycle.

How long does a released egg last in the female reproductive tract?

A released egg typically lasts for 24 hours in the female reproductive tract.

What is the significance of estrogen levels in relation to sexual desire in females?

Estrogen levels can increase sexual desire and libido in females, particularly around or prior to ovulation, potentially increasing the likelihood of intercourse.

Why do males produce such a high number of sperm cells daily compared to the number of eggs a female releases?

Males produce a high number of sperm cells daily as a 'shotgun approach' to increase the odds of fertilization, given that females typically release only one egg per cycle and have concealed ovulation.

Keywords

💡Consensual Coitus

Consensual Coitus refers to sexual intercourse that is mutually agreed upon by all parties involved. In the video, this term is used to emphasize the importance of consent in sexual activity. The script discusses the best time for consensual coitus from both a reproductive and enjoyment standpoint, highlighting the significance of mutual agreement and comfort in sexual encounters.

💡Sperm Production

Sperm production is the process by which sperm cells are generated in the male testes. The video script explains that sperm cells are produced at a high rate, with up to 300 million sperm cells per day, which theoretically allows males to engage in sexual activity at any time. This concept is crucial in understanding the male reproductive capacity and the discussion around the best time for sexual activity from a male perspective.

💡Testosterone

Testosterone is a hormone that plays a key role in the development of male reproductive tissues and secondary sexual characteristics. The script mentions that testosterone levels peak in the morning, which can lead to increased libido and the ability to maintain an erection. This information is relevant to the discussion on the best time for sexual activity from a male performance standpoint.

💡Ovarian Follicles

Ovarian follicles are structures in the ovaries that contain and protect the eggs (ova). The video describes how follicle-stimulating hormone (FSH) stimulates the development of ovarian follicles, typically leading to the maturation of one dominant follicle that releases an egg during ovulation. Understanding ovarian follicles is essential for discussing the female reproductive cycle and identifying the best time for sexual activity from a reproductive perspective.

💡Ovulation

Ovulation is the process where a mature egg is released from the ovary, typically once per menstrual cycle. The script explains that ovulation is triggered by a surge in luteinizing hormone and is a critical time for potential fertilization. The video uses ovulation as a reference point for determining the optimal time for sexual activity for females aiming to conceive.

💡Estrogen

Estrogen is a hormone that is primarily responsible for the development and maintenance of female reproductive tissues and secondary sexual characteristics. The video script notes that estrogen levels rise prior to ovulation, which can increase libido and the desire for sexual activity. This hormone's role is pivotal in understanding the female sex cycle and the timing of sexual activity for both pleasure and reproductive purposes.

💡Sexual Desire

Sexual desire, or libido, refers to an individual's sexual interest or appetite. The video discusses how both testosterone in males and estrogen in females can influence sexual desire, with morning testosterone levels and estrogen levels prior to ovulation potentially enhancing the desire for sexual activity. This concept is integral to the video's exploration of the best times for sexual activity from an enjoyment and performance perspective.

💡Endorphins

Endorphins are neurotransmitters that function as natural painkillers and are associated with feelings of pleasure and euphoria. The script mentions that sexual activity can lead to the release of endorphins, contributing to the positive feelings experienced during and after intercourse. This physiological response is part of the broader discussion on the benefits of sexual activity and the potential for increased happiness and reduced stress.

💡Oxytocin

Oxytocin, often referred to as the 'love hormone,' is a hormone that plays a role in social bonding, trust, and sexual reproduction. The video script explains that oxytocin is released during sexual activity and can contribute to feelings of connection and bonding with a partner. This hormone is highlighted as a key factor in the emotional aspects of sexual activity and its potential to enhance relationship satisfaction.

💡Female Sex Cycle

The female sex cycle, also known as the menstrual cycle, is the hormonal cycle in females that prepares the body for potential fertilization and pregnancy. The video script provides an overview of the cycle, including the roles of FSH, LH, estrogen, and progesterone, to help determine the best time for sexual activity from a reproductive standpoint. Understanding the female sex cycle is crucial for the video's exploration of optimal timing for intercourse.

Transcripts

what is the best time to have

intercourse or would I like to refer to

as consensual coitus now many of you

might fall into the camp of anytime is

the best time to have sex or intercourse

well is that true and are there

anatomical and physiological

considerations that might make one time

better than the other well in today's

video we're going to answer some of

these questions and look at it from say

like a reproductive standpoint as well

as an enjoyment in performance

standpoint we'll take a look at some

testes and ovaries and look at various

hormones to help us answer this question

of the best time for consensual coitus

it's gonna be full of all sorts of

anatomical awesomeness so let's do this

so let's quickly start with the male

perspective because one could

potentially argue that males could be

ready to go Anytime Anyplace anywhere

and this idea comes from the way in

which sperm cells are produced so let's

have a blast from the past my younger

self explain how the sperm production

applies to what we're talking about by

taking a look at a right testicle and

you can see this is the actual right

testis here pretty amazing structure but

we need to show the internal anatomy of

this right testis here we go

look how amazing that is inside and if

you look closely in there it almost

looks like there's a little these little

stringy type things here and these

little stringy things are tiny little

tubes that are in each testis in these

little stringy tubes are called the

seminiferous tubules there are up to 900

of these in each testis that's why again

it looks like little stringy things that

are tiny and these seminiferous tubules

are where sperm cells are produced and

producing sperm at what some may

consider an alarmingly high rate they

can produce up to 300 million sperm

cells in one day

if we were to average that out over a

day that's approximately 12.5 million

per hour 208 000 per minute and about 3

500 per second

I just created 3 500 sperm cells

and 3 500 more look at me go so based on

what we learned there from a

reproductive standpoint males should be

able to reproduce it pretty much any

time but from say like just a daily

performance standpoint is there a best

time of day for males to participate in

intercourse well testosterone levels

tend to be the highest in the morning

around 8 A.M and as many emails have

experienced this often comes coupled

with increased libido and sex drive and

also is coupled with that magical

increased ability to maintain an

erection

all right oh my God I'm sorry

now having the potential for increased

performance in the morning is one thing

but are there actual benefits to having

intercourse in the morning often when

you hear about the benefits of

intercourse you'll hear people talk

about the release of certain chemicals

like release of endorphins from the

brain or release of hormones like

oxytocin for example endorphins are

these natural painkillers that the body

releases but they're also associated

with feelings of pleasure in Euphoria

oxytocin also has many functions but

this hormone is linked to connection and

bonding and why it's often nicknamed The

Love hormone now people have been

surveyed about morning intercourse and

many people have reported increased

connection to their Partners a decrease

in stress levels throughout the day as

well as increase happiness throughout

the day and many have also even reported

that they felt more productive while at

work so at the very least we should

consider participating in morning

intercourse so that we can be more

productive members of society and we do

have to say that not everyone reported

those benefits and it doesn't mean that

people couldn't have amazing bouts of

intercourse at other times throughout

the day so what should we do with all

this yes there are some potential

benefits of morning intercourse that

could prickle throughout the day but I

think some of the best advice that

people could be given is that it could

be wise for someone to practice having

consensual coitus at multiple different

times throughout the day and then of

course document write it down for

science so that you can know the pros

and the cons and what works best for you

so now let's take a look at this from

the female perspective and as you can

see we've got some charts and some

hormones listed up here to help us

understand the female sex cycle so that

we can figure out if there's a best time

for females to participate in

Intercourse now one of the things that I

do want to mention is that the female

sex cycle is super awesome and amazing

and I think when people understand this

they tend to have a better appreciation

for reproduction and you might also

notice that I said female sex cycle a

lot of people will refer to it as like

the menstrual cycle or just a monthly

cycle but most physiology books we'll

call it the female sex cycle and you can

see we've listed it from Day Zero to day

28. keep in mind there can be variation

in this depending on the female anywhere

from 20 days up to 45 days but we kind

of put it in the middle or close to the

average of about a month or 28 days so

let's start with follicle stimulating

hormone and we're not talking about

stimulating hair follicles here we're

talking about stimulating follicles that

are inside the ovaries or ovarian

follicles now an ovarian follicle is

just a single layer of cells that

encompasses or encases an ovum or an egg

so think of the follicle as like this

little container for a single egg now at

the beginning of the cycle you'll see a

little bit of a bump in this FSH and

just FYI the beginning of the cycle day

Zero is when menstruation or bleeding

and those period cramps start and again

that's accompanied with that little bump

in follicle stimulating hormone and that

FSH will cause about 6 to 12 ovarian

follicles to start to develop and mature

what's interesting and important to note

is that even though 6 to 12 start to

develop and mature typically only one

fully develops and matures and will

release its egg and we'll get to that in

just a second but let's go to

luteinizing hormone real quick you can

see about the middle of the cycle it

spikes like crazy and this spike in

luteinizing hormone this causes

ovulation to occur and it does get a

little synergistic bump from that

follicle stimulating hormone as well but

we need that luteinizing hormone to

cause ovulation now if you haven't heard

of ovulation or don't know what it is we

can just say that it's pretty much when

the ovary releases that egg from that

one mature follicle that we saw now

there are times where people can be like

hyper ovulators or ovulate more than one

egg or release more than one egg and if

both of those eggs or multiple eggs got

fertilized that's when you would have

like non-identical twins at least that's

what people will refer to them as but

they have the same likeness as like any

other sibling but again most of the time

one egg gets released during ovulation

during a 28 day cycle

compare that to 300 million plus sperm

cells per day that's crazy to think

about and to make it even more crazy is

once that one egg gets released that egg

will only last for 24 hours so you might

be thinking how in the world did we

create so many humans if the egg only

lasts for 24 hours well let's see if we

can do some things to potentially

increase the odds of fertilization in

creating a human well one of the things

that we'll see is that we've got this

other chart here we've got the estrogen

in red and the progesterone in blue

we're not going to talk much about the

progesterone we've got some other videos

that go into more details that I'll link

to this video but with the estrogen

we're going to see that the estrogen

starts to greatly increase around that

same time or prior to ovulation at day

14 and prior to that spike in

luteinizing hormone now estrogen does

some amazing things with female anatomy

and physiology but one of the things

that it also gets involved in is

increases in veto and sex drive and what

I'll often will tell students is that it

makes sense to potentially increase

sexual desire libido around or prior to

releasing an egg and what's interesting

is you know maybe that female's partner

forgot to do the dishes or forgot to mow

the lawn or forgot to text her back or

whatever it may be but because of that

huge spike in estrogen that might makes

the female Overlook the shortcomings of

that partner because estrogen is saying

we don't care about all those things we

need to participate in successful

reproductive intercourse now that

increases the potential likelihood to

participate in Intercourse around

ovulation but that doesn't really extend

that 24-hour window

what can in a way extend that 24-hour

window is what I like to refer to as

those pesky little sperm cells those

pesky little sperm cells have been known

to last three to five days in the female

reproductive tract after intercourse

some Studies have shown even potentially

up to seven days in rare cases but the

majority of the time you're talking

three to five days so that means if the

egg gets released on day 14 during

ovulation lasts 24 hours to day 15 that

means from day 15 if we had intercourse

three to five days prior to that maybe

even seven days if you had super crazy

Kryptonian sperm cells but again more

like three to five days prior to that

you could have successful reproductive

intercourse because those sperm cells

would be ready and waiting if they were

in there prior to ovulation now if we're

talking what is the best day or time

from a reproductive standpoint from the

female we're talking the day before

ovulation in the day of ovulation and

would be the prime time to have

intercourse again if we're talking about

reproduction so let's go into a little

bit more detail of why in the world is

there such a huge difference between

male and female gamete production the

gametes just being the eggs and the

sperm cells now with the female we did

see that only one egg is typically

released during a full 28-day cycle

whereas males we had those 300 million

plus sperm cells created per day so why

in the world would you need 300 million

sperm cells per day if there's only one

egg released per 28 day cycle well you

can definitely make the argument for

this shotgun approach releases many

sperm cells onto one potential Target to

increase your odds of fertilization and

having successful reproductive

intercourse there's also the perspective

of with female humans they have what's

called a concealed ovulation they don't

go into heat like other animals do and

have those more obvious signs of being

in that state of getting ready to

ovulate like the other animals and

speaking from a male perspective I have

no idea when a female is ovulating it's

not like I have ovulation radar or what

we could call an avdar or some ovulation

spidey sense now some females have an

idea sometimes when they're ovulating

some might notice that they have actual

ovulation pain they can notice a slight

increase in body temperature changes in

cervical mucus and even things like

breast tenderness but that's still not

perfect because there are some people

who will

tried to do birth control by avoiding

having intercourse during that time

period around ovulation and sometimes

they get it wrong and they end up with a

little bit of a surprise but again

coming back from this to this male

perspective of not having avdar or some

ovulation spidey sense it would

therefore make sense to create as many

sperm cells as possible so the male can

always be prepared and ready to go for

the Glorious ovulation day and let's

wrap this up with one more thing about

the female perspective because likely

most females are going to want to have

intercourse more than once per 28-day

cycle so like we did with males earlier

is there a better time or best time to

have intercourse from the enjoyment or

the performance aspect for females while

some researchers have shown that

estrogen levels could be a little bit

higher in the afternoon now don't get me

wrong we're not talking about those huge

spikes that we saw on the graph but just

slightly higher than say at other times

of the day with also potentially

elevated cortisol levels where the

female might feel more energetic a

little bit more of an increased sex

drive and might have a great time during

the afternoon however there are also

plenty of females who reported similar

things to males with intercourse in the

morning so we come back to this whole

situation from an emotional a connection

a performance and even an enjoyment

standpoint there's not a definitive

answer which probably isn't that

shocking to everybody but again I would

say for females and everybody do that on

self-reported Research where you

practice consensual coitus throughout

the day and see what works best for you

and what's interesting about this is I

always joke with my students and say our

brains are sometimes too big and too

smart for our own good because our

sexual desire preferences and how we

participate in Intercourse is much more

complex than other animals we have all

these things that get involved with

attraction and how we participate in

Intercourse more than just what our

hormones are telling us so if we cut out

all the fluff of like I said the

connection the emotions the enjoyment

performance Etc and we just became

biological reproductive robots then yes

we could say

the best time to have intercourse is in

the morning on day 14 right before

ovulation one of my favorite things

about teaching anatomy and physiology

and just about the human body is the

ability to apply that information to

real world situations so if you enjoy

learning how to better apply scientific

principles to real life situations or
