Have you ever saw a clitoris?

Penis and clitoris have absolutely different functionality and structure.

Do you think women pee and give birth through clitoris? That we shoot ova through it?

Lmao you learned about sex organs on a site called “ohjoysextoy.com?”

Solid source. Probably the best place to go for sex education.

I’ll ask the most obvious question: how are babies made?

Follow up: if male and female sex organs are the same, why is it that only females get pregnant and menstruate? Why do males and females have entirely different functions when it comes to genitals?

Another follow up: have you ever actually seen both a male and female body? I may be going out on a limb here, but I feel like, even just visually, there’s quite a few distinct differences.

Last follow up: if male and female sex organs are the same, why do some trans people get or want bottom surgery?

Hair, fingernails and rhino horns are all made of the same stuff so they are all the same things. Genius deduction.

I mean, we're all mammals in the end, right? We're all made from the same things. So I'm a wolf!

No. You have gotten it wrong. This is clearly explained in the sub so many times. Read a single post before posting an embarrassing essay on how you misunderstood how a baby is made.

As for your sources-

A sex toy site is not a reputable source for this topic

Neither is Quora lmao, it’s literally a site where anyone can answer with anything.

As for Medical News Today- the first sentence starts with “while women do not have prostates...” something you acknowledge, yet don’t seem to understand the meaning of.

“Researchers have discovered that the Skene glands share some of the same properties as the male prostate“

Trolling

All cells in your body have the exact same genetic material and ultimately come from the same cell, the zygote, which is the result of the fusion between an ovum and a spermatozoa. Does this mean all these cells are the same? Well, certainly they are not. If you take a look at, for example, a neuron, a hepatocyte, and a muscle cell you'll see they are quite different both in form and function. So, all your cells have the same DNA, yet there are different kinds of cells and it's those differences what makes it possible for your cells to form the different tissues and the different organs in your body.

How is it possible that all those different cells exist? That is because that, despite sharing the same DNA, not all cells express the same genes. Indeed, some genes are only expressed in certain cell types, under certain conditions or under certain life stages. It's this difference in gene expression what makes a neuron, a hepatocyte and a muscle cell different from each other. The process by which cells become more specialized is called cell differentiation and it starts right after conception.

Meanwhile, your sex is determined at conception depending on whether you have a Y chromosome or not. In XY embryos, the primitive gonad differentiates into testes and, in XX embryos, it differentiates into ovaries. The hormones secreted by the testes drive the male differentiation pathway for the rest of the male reproductive organs. And the absence of these hormones drives the female differentiation pathway.

All this explanation was to say that clitorises and penises are different organs despite being derived from the same embryonic structures. By the way, not all reproductive organs have a counterpart in the opposite sex. For instance, Müllerian ducts develop into the uterus, the fallopian tubes and the upper part of the vagina in females, but these ducts regress in males.

You can read a more complete explanation of sex determination and sex differentiation here.

I've always said that males are mutated females. Too much testosterone creates mutants i.e. males.

I can't think of the name of it, starts with a c, but it's like kryptonite to males... harms/kills them in the womb.

Edit: cortisol

Clitoris and penis are not the same thing. They are formed from the same tissue in embryonic development. Fetuses prior to sex differentiation have all the same sex organs because the organs haven't developed yet, just the base tissue that they will form from. After sex differentiation they have different organs. In the same way that both hair and fingernails are made from the same base tissue, yet develop along different pathways and become different structures.

[–]MarkTwainiac 4 insightful - 1 fun4 insightful - 0 fun5 insightful - 1 fun -  (3 children)

Correct me if I am wrong, but sex differentiation in humans begins in the embryonic stage. There is no such thing as "fetuses prior to sex differentiation." By the time a human in utero becomes a fetus - in the 9th week post fertilization, the 11th week of pregnancy - sex differentiation in the organs been established.

Recent research shows that sex differentiation in humans is observable at 6/7 days post fertilization, when the zygote is becoming an embryo.

[–]SilverSlippers 5 insightful - 1 fun5 insightful - 0 fun6 insightful - 1 fun -  (2 children)

Okay. So I looked it up. SRY activates at 6 weeks, and the unborn human is considered a fetus at 10 weeks. So you are right there, I wasn't well versed on when an embryo becomes a fetus.

Anyway, sex is obviously there at conception, but gonad and genital tissue doesn't differentiate until 6 - 8 weeks.

[–]MarkTwainiac 5 insightful - 1 fun5 insightful - 0 fun6 insightful - 1 fun -  (1 child)

I don't think most people are well versed, or even aware, about when a human embryo becomes a fetus unless they are biologists, fertility doctors, ob-gyns or have dealt with the issue personally and directly by TTC, being pregnant and/or having miscarriages - or having a partner or someone else close to them who has done so.

The impression I get is that most posters here have not had these personal experiences (yet).

It's true that human gonads don't clearly differentiate until 6-8 weeks.

But it's not necessarily true that until that point there's no observable/observed sex differences in M & F human zygotes or embryos.

It's long been customarily assumed that sex differentiation in humans and other mammals begins with gonadal development and the hormone differences that result - and that all the rest of the sex differences in humans follow from, and are the result of, developing different gonads & sex hormones. But research into genes and stem cells in recent decades has shown this not to be the case.

"Robust sex differences" have been found in the progenitors of placenta cells of M & F human zygotes as early as 5 days post fertilization. (The placenta usually forms at day 6/7 after fertilization.)

The placenta is required for the growth and survival of the fetus during pregnancy, and facilitates the exchange of gases, nutrients, waste products, and hormones between maternal and fetal circulation. The placenta is formed 6–7 days postconception, and is composed of specialized epithelial cells called trophoblasts [1]. Trophoblasts are one of the earliest lineage differentiation events of the mammalian embryo, arising from the outer extraembryonic trophectoderm cells of the preimplantation blastocyst. During implantation, trophoblasts invade the maternal epithelium and differentiate into two types of specialized progenitor cells [2]. Syncytiotrophoblasts (SYNs) are multinucleated terminally differentiated cells that synthesize hormones for sustaining pregnancy. Cytotrophoblasts are mononucleated undifferentiated progenitors that can differentiate into SYNs and extravillous invasive trophoblasts (EVTs), which anchor the placenta to the uterus. These early differentiation events are essential for placental formation, as impairments with trophoblast cells result in miscarriage, pre-eclampsia, and intrauterine growth restriction.

Fetal sex influences in utero development in healthy and complicated pregnancies, where male fetuses have increased risk of peri- and postnatal mortality, and females are smaller during gestation [61–63]. Because predisposition to many adult diseases that are sexually dimorphic (including type 2 diabetes, depression, and coronary heart disease) originate during this period [64], it is important to understand the origin of these sex differences. A number of reports profiled the placental transcriptome using full-term placentas and found sex differences [65–67], yet there are no studies examining the initial stages of trophoblast formation, which occurs early during the first trimester. Here, we used an in vitro differentiation model system, where hESCs are converted to trophoblastic cells using BMP4/A/P culture conditions, to identify sex-specific expression profiles for the progenitor cells of human placental trophoblasts.

We found that there are robust sex differences in hESCs, the differentiation pathway of hESCs to trophoblastic progenitors, and in differentiation day 5 trophoblastic progenitors.

That hormonal theory looked really weird.

Our bodies are different on the very basic level - hormones would not change the base. It's not like adding or removing hormone will change pelvis and joints placement and development - they are different in their core, in the very origin. So it is strange that such idea even existed for so long.

It includes a chapter on human development.

I’m obviously not GC but even I don’t agree with this. They have the same root and structural similarities are evident but if you build a canoe out or a tree it’s still different than if you had made a cabin out of it.

Also, every cell in every organ in our bodies, not just the sex organs, contains our sex chromosomes. In 99.99% of cases, human sex chromosomes are either XX or XY. Female and male cells throughout the human behave differently at the cellular level. Which leads, for example, to male and female humans having different kidney function and levels of immunity.

[–][deleted] 1 insightful - 1 fun1 insightful - 0 fun2 insightful - 1 fun -  (1 child)

That’s literally not true. For instance red blood cells don’t contain sex chromosomes.

[–]MarkTwainiac 7 insightful - 1 fun7 insightful - 0 fun8 insightful - 1 fun -  (0 children)

You're right. I should have said that all nucleated cells in the human body have sex chromosomes, and that nearly all cells in the human body are nucleated.

Red blood cells have no nucleus so they are without sex chromosomes; this is apparently true of mature cells in the human eye lens as well. These are the only exceptions known so far.

Thanks for correcting me.

Males have clitoris, vagina, womb, ovaries, etc,

I think you suggested the penis as an analogy for the clitoris despite the problem of the urinary tract. Was there even an equivalent male body part for vagina and womb?

I imagine you would claim the ovaries and testes were somehow the same, even though they can be considered exactly what distinguishes us - producing different hormones, different gametes, at different times. You can see the similarities of a hoof and paw, of an apple and an orange, but they are not the same. Being able to compare something does not make it identical - it usually makes it separate. When you can describe something generically with no need to clarify "the major difference" then you can say it belongs to one category.
