A Twitter user posted this tweet on Twitter.com earlier today:

Knowing that EVERY penis started out as a vagina should help u to better understand why some men are such bitches

Twitter user @bprocks56, a male, asked: "how is that when Adam was created before Eve? #blankstare"

I saw this as a teachable moment: clearly some people aren't aware that all embryos have the same female genitalia until about the 8-12 weeks of gestation. This is why the sex of a baby can't be determined by ultrasound until after the sex organs are formed.

Here are male and female 9 week old embryos. Can you tell which is which? Click here to see the answer.

    Wow Sandra!! Now this was interesting. I had no idea that we all started out the same. Great medical minute-ish post

  • mrsloveleigh

    lol i thought it was very interesting. kinda makes me think about the peeps going through gender issues. maybe it's because at one point you basically had both.

    "Knowing that EVERY penis started out as a vagina should help u to better understand why some men are such ****es"

    It should also help explain those folks that feel like they are the "wrong" gender. Cause maybe they are.

    Those pics though... :nono:

    This post needs a NSFW tag, STAT.

  • BlackBeauti

    Sandra thank you for enlightening me but what about those born with both a vajayjay and a painis????

  • LuvMySailor

    Thank you Saundra!! I learned this in my Ministry and Sexuality class in divinity school.

    @BlackBeauti I'm going to assume that the genitals did not separate correctly due to mutation

    Thanks for the post Sandra!! Very interesting....

    I find it funny how some people always speak on things as if they're experts in the field. Especially on social networking sites such as Twitter & Facebook, like it's true because they said it. LOL!

  • http://chokolatemilk.blogspot.com Choco aka Hippie

    How come some folks find the pic of a fetus disturbing just wondering?

  • http://www.funnyordie.com/videos/5d5eb1d6c7/go-the-f-ck-to-sleep-as-read-by-samuel-l-jackson YSoSerious

    @LAKEYA

    I think Sandra hates just about everybody except a chosen few. And I still think she secretly hates at least a couple of those. :lol:

  • brenden

    I think I was able to guess right because I've seen several vaginas up close. Don't ask, I won't tell. It was the position of the anus in relation to the genitals that gave it away for me.

  • mrsloveleigh

    Choco I was disturbed at how lil the baby was. looks almost sickly. Probably a preemie though. Nothing like a nice plump baby

  • http://chokolatemilk.blogspot.com Choco aka Hippie

    @Mrs
    Of the pic of the real baby yeah the baby is tiny but I love them regardless :lol:

  • http://gumbumper.com/ Gumbumper

    Sandra, thanks for this good information.

  • trenee

    thanks for this! good to know!

  • dwanell89

    I got could tell the difference but SMH @ my logic. I figured the female's butthole would be close than the male's, lol.
