Many people – particularly those couples trying to conceive – have requested a pre and post male ejaculate photos. So, in the interest of home science – and not so much for romantic pleasure 
– we took this series. We are not trying to conceive, which is why we chose this day of my cycle to experiment with.
Both photos are taken on the day before I began bleeding – you can see some fresh blood at the os. The first is pre-arousal. The second is taken about an hour later, after both male and female orgasm. You can see a pool of seminal fluid on the bottom. The cervix was much farther back in the vagina during the second photo shoot due to the ballooning of the vagina during arousal.
The sperm retention theory describes the cervical contractions and dipping in and out of the vagina as an evolutionary advantage of female orgasm. This theory posits that the rippling muscle contractions of the uterus and vagina during female orgasm shift the pressure in the uterus also causing the cervix to gape and suck (imagine a turkey baster if you rhythmically squeeze it). If the man has already ejaculated at this point, the dipping, gaping, and sucking movements of the cervix will help draw in the semen that is present in the vagina into the os and uterus (particularly if there is fertile cervical fluid present). If the speculum weren’t opening the vagina, the os would be sitting in a pool of semen.
Some say this theory is a myth. Check out this article about other scientific research on the role of the female orgasm.

I’ve heard of the “upsuck theory” and have seen the video. Its an interesting idea and deserves to be studied more but if I remember correctly, its only been observed and recorded once. More research is needed.
Maybe someone here could take pictures as soon to orgasm (before and after) as possible and provide more evidence? Just wondering.

I found and looked through your amazing photos. My goal was to try an figure our if a tampon could get shoved or lost inti the cervix. Or to see If it could possibly be hiding under folds of tissue?

A Tampon will not fit onto the cervix. They can move around in the vagina, though. Make sure to always have the string outside your body. If the string falls off (rare!) or if it gets pushed inside, you can insert your finger inside your vagina (you may need to insert your longest finger all the way inside) and move it around until you find it – then coax it out.

Really great pics, thanks a lot. If you want to go on with pictures concerning sex, maybe a lot of people would also be interested how it looks like, when you put a diaphragma on your cervix.
Have fun and thanks for you pics!

For a murder mystery novel, I am researching post-coital effects of vaginal intercourse. Specifically, would a medical examiner be able to tell from examining the vagina that a woman had had intercourse 30 minutes to an hour before her death? What would he likely see?

The evidence in the vagina suggesting exact timing of sex is limited, but through examining the semen under a microscope the ME would be able to tell if the sex had occurred within a few hours of the body being FOUND since sperm can only survive the acidic environment of the vaginal cavity for a few hours. Not terribly exact. If sperm is still present, there might not be any live swimmers but they can still tell the difference between semen and vaginal secretions, then the woman had sex relatively shortly before being killed, ranging anywhere from hours to minutes before death. Something else to consider is that when a woman stands up and moves around a good portion of the semen will, sorry to be graphic, will slide out, leaving little residue behind, but enough for an ME to know the woman had sex within the last 24 hours. It is for similar reasons that an OB/GYN requests that a woman abstain from sex for 24 hours before a pelvic exam. There would also be bruising or inflamed areas in the vagina and on the labia if the sex was rough or forced. Hope that answered your questions.

Thank you for the pictures and the commentary about pre and post arousal. Yes, not many women are aware of the actions of the cervix and uterus during coitus. Some women are aware and this causes deep concern for some about hysterectomy.
thank you again-

These are amazing! Thank you for taking the time and effort to take these photos and share them.

You could try stimulating your clitoris (with your fingers or a vibrator) while he is penetrating you.

Causes of bleeding after intercourse vary. Could be from vaginal dryness (little tears in the walls of the vagina), a cervical or uterine polyp, PID, hormonal imbalance, etc…I encourage you to contact your practitioner to rule anything serious out….

Hi, thanks for the very informative article and photos. I was trying to do some research when I chanced upon your website. My husband told me his penis feels a sucking sensation in my vagina. It gets him more aroused and he would have an orgasm/ejaculate. I was curious and wanted to find out what he meant by sucking sensation. Now I realised it is cervical contraction after orgasm.
Cheers!
[Reply]
Oh, I mean during orgasm, not after.
[Reply]
pls help me out, I’ve been trying to conceive, how can my husband place his penis right to my cervix for easy swimming of the sperm to my uterus or fallobia tube
[Reply]
I have a question….Me and my fiance are trying to conceive; anyway when we were having sex the other day he told me that when he went really deep he could feel a really small tight hole and trust me it did hurt. Anyway he ejaculated there; is it possible that he ejaculated in my cervix?
[Reply]
I am so glad to have found this website. Your photos and the article are really helpful.
My husband and I are trying to conceive. We’re trying to have sex at night because we have heard this is better than morning sex and then we’re trying to wait 24 hours until he ejaculates again. The trouble is, we also want to have sex in the morning. I’ve two questions – do we need to wait 24 hours for the sperm to regenerate? And if we have intercourse in the morning but he doesn’t climax can that in any way affect our chances of conceiving from the sex the night before (such as by creating a vacuum and disrupting the sperm that’s already in position). Sadly I don’t (and have never) orgasm so there is unlikely at any point to be any of the sucking motion that may occur with organism.
Oh, one more question – after evening sex, is there a position I am best to lie in to enable the sperm to swim through my cervix?
Thank you so much for helping people on this.

If a girl had sex, got pregnant, didnt know it and went for her pap a few days later, could gynecologist see that she was pregnant just by looking or how far along would she have to be for him to be able to tell just by looking?
