Pre and Post Coitus

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 male 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).  I imagine that 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.

  2. Wow, girl. Thanks for that educational experience. It’s amazing to me that you can photograph your vagina and cervix. I’ve just finished a pre & perinatal psychology course. Quite profound. And I’m interested in the work you are doing now. Where are you living? Is it true you’ve become a midwife?

  3. These pictures, and your whole website, are so great and informative! I’m sending this to everyone I know. You should publish a short book of photographs!
    Thanks for your time and effort!

  4. Now this is what I call having sex in the name of science!

  5. “I imagine that a woman with a non-retroverted uterus, whose cervix points more midline or posterior might have her os sitting in a pool of semen.”

    I imagine yours would be sitting in the pool of semen too if it weren’t for the speculum stretching it open. Just a note, in case women trying to conceive think that the semen isn’t getting close enough. This just takes a little visualization, obviously, because there isn’t really all that space in there that we see in these pics.

    Thank you for this site. It’s been very helpful for me in learning all I can about my fertility as my husband and I are trying to get pregnant!

  8. Fantastic!
    These photographs provide more information than books on the subject of anatomy and sex. None of see our vagina or cervix so to see this in some detail is amazing.
    There is evidence of the vagina having swollen during coitus but you haven’t mentioned this but maybe your head was still spinning afterwards.

  9. Great pics!

    I will direct my patients to your site next time they ask me about the “inner details” when you are trying to conceive…

    Warm regards,
    Joachim

  10. As a guy who loves anatomy/the human body and loves women, I cannot thank you enough for these pictures. Very illuminating.

    Comment by Morgan — April 2, 2009 @ 9:17 pm

  11. Please take more pictures pre and post coitus during different phases of the cycle. Excellent job. We would certainly like to see the cervix post coitus and post orgasm near ovulation. Thanks.

    Comment by Marvin Stevens — April 6, 2009 @ 3:42 pm

  12. We are NOT trying to conceive, so we will not be having unprotected sex during ovulation for the sake of this project, but if anyone else wants to participate in this way, they are invited to do so :)

    Comment by beautifulcervix — April 6, 2009 @ 8:08 pm

  13. Thank you very much for these pictures. So many sites have pictures of males ejaculating but not what happens when a women ovulates. It was very informative, and helped a lot to answer my questions that I cannot seem to find anywhere else. Please keep up the good work, for the medical community and the public as well.

  14. These are very educational and it is wonderful to have them. Thank you for doing these pictures. Have you considered shooting some pictures during pregnancy?

    Comment by Alison — April 18, 2009 @ 6:20 pm

  15. do you know were i could view a cervix at various stages of pregnancy please me and my husband are trying to concieve and your pictures have been amazing in helping us thank you so much xx

  16. I too had a retroflexed/tipped uterus. I found laying on my stomach post-coitus to be more conducive to conception for precisely the reason you mention above. Every woman should have a speculum and should be empowered to know her own body. The most empowering internal exam I ever had, the midwife told me to put the speculum in myself. What a profound shift in the power dynamic!

    Comment by abrax — June 28, 2009 @ 6:47 am

  19. Thanks so much for “sacrificing” some romance to do this! Helps so much to understand my body better. I am seconding the requests for pictures of pregnant cervix. My ob/gyn told me today I might be pregnant since my cervix looks “pink”. (can’t test for a few days) I say “great” beacause we’ve been trying for a year but then I just had to scratch my head – what does that mean exactly? If you know of another resource to help me with this puzzle please do tell? Thanks again for the blessing of this site.

  21. whao!!!,this is one great work of dedication and passion.i am greatly impressed,especially living in this area of the world,where little or nothing is known about cervix examination and even when known little information is given.I really do love this site and thank you so much.

  22. Hi, magnificent pictures !!!

    Very educative without doubt.
    I’d like to know (even if that topic might be becoming boring for certain men, let alone women) if a man with a 10 inches penis fully erect wants to have intercourse with a woman having a vagina of 3 inches before arousal, how is it posssible to avoid discomfort or even bleeding of the cervix?

    Comment by Gabriel — August 26, 2009 @ 4:59 pm

  23. This is awesome! I’m directing all my friends to this site!

    Comment by zops — October 28, 2009 @ 7:50 am

  25. This is a wonderful website, truly a work of love I can see. However, in this page you repeat a myth about the uterus as if it is fact. The uterus does not work like a turkey baster and it doesn’t suck up semen during orgasm. This is a very popular idea that happens to be incorrect.

    Think about how a turkey baster works. If you stick it in the dripping, but don’t squeeze it does anything come into the baster? Nope. One had to squeeze the air out of the bulb (the uterus) of the baster to create a vacuum when pressure is released to suck whatever into the baster. There is no air in the uterus and prior to orgasm the uterus doesn’t contract and expell something so that there could be a suction if the uterus expands during orgasm. Of course the uterus doesn’t expand during orgasm, it contracts so if anything the uterus would expell whatever is inside of it during orgasm. This is why women experiencing orgasm during their period often experience a gush of new blood at orgasm. The physics works in exactly the opposite direction as described.

    This common misconception can be found in the scientific literature. It’s a nice story, but that’s all it is, a story. It’s not true.

  27. Your site it amazing! I would’ve never thought we’d be able to see a cervix in this light. And kudos to you and your bf for having the gusto to take post-coital pics. I’m off to look at more photos and sharing this site with all my mommy friends! Thank you so much again and good luck with your project!

  28. beautiful cervix.com is a great site I am in a TEEN LIFE class in COOP HS and WE needed this to answer a lot of our questions just like the Pre- and Post picx. So much is being learned everyday in our classAbstain is a fariytale and always has been let’s be real and live productively intelegent.

    Comment by Chloe — November 19, 2009 @ 6:58 pm

  29. Kim Wallen : HI
    Teen Life class of Co0p High. We understand the idiogram of the turkey baster, We know it only takes a nano gram of semen to rush into the follical of the Fall-open tubes[te he ha ]so the Sucking would accually be just what ‘klings’ to the edges of the cervix as it becomes Enlivened and that is enought to put it down under the blanket of friendly environment.actually osmosis in a ,loose way, thru the contracting orffice. An Historic reference here is to ‘cervix plugging’ with the dried skin of kelp leaf skin, after coitus it would swell and fall out.
    Though male contraception was intrals of animals/Fish/birds. The skin of Slick skined fish[catfish]and even Trout with the tiny micro dot scales left intact. preverved in fish oils not rolled l1ke those of today. BUT we do have lamb skins that are still ‘tied on with a small closure string at the base after erection.

  30. the first photo in here:
    http://www.beautifulcervix.com/cervix-photo-galleries/photos-of-cervix/pre-and-post-coitus/

    looks like there is a hair in the mid lower part, it is going almost vertical ;-) nice work!!!!

    more please, how about one just before woman orgasm (post arounsal) and one after women orgasm (without the male ejaculation), thanks

  31. wow…. its so nice to read and i`ve learn a lot all of your information…good luck and keep up the good work.

    Comment by ohgaki — February 8, 2010 @ 8:33 am

  32. About the sperm retention theory – if you watch “The Human Animal” it was a documentary you can see it in action. They recorded the cervical action of dipping into the semen.
