If what makes a male or a female is the production of sperm or egg, then that means men or women who can not produce sperm or egg are not male or female by definition.

You misunderstand. Male and female are not defined by production of sperm or egg, but by the potential capacity to produce sperm or egg at some point in life. Many girls and boys die before the age when they can produce sperm or or mature and release eggs. This does not mean they died as sexless beings.

The sex of a human fetus can be easily ascertained in utero at 9 weeks via the non-invasive NIPT or invasive CVS. This is why so many female fetuses in various countries are being aborted simply for being female. Also, one in nine girls born alive in India today will be killed by age five simply for being of the female sex.

You're also using a male-centric definition of sex. Fact is, female humans are born with all our eggs already intact. We do not produce new eggs in our lifetime upon sexual excitation and orgasm the way males produce sperm; our bodies attempt to preserve some of the eggs we already had in utero coz in the natural course of events our eggs deteriorate and die off over the course of our lives. During and after puberty, girls and women's eggs mature and are released one by one on a regular basis during the ovulation-menstrual cycle. No matter how much sexual excitation or orgasms a girl or women experiences, this in no way causes her to mature or release eggs or otherwise affects her fecundity.

And if what makes a male or a female is the genitals, then a male or a female who removed all the sex organs in surgery is not a male or female anymore. By definition.

This is a very male POV. Only the male genitals include male gonads, the testes, where male gametes come from. Female gonads, the ovaries, where female gametes come from, are entirely internal. A female can have entirely altered genitals and still have her gonads and other reproductive organs intact.

a male or a female who removed all the sex organs in surgery is not a male or female anymore. By definition.

Pray tell, what people of either sex do you know or have you ever heard of who've had all their sex organs removed?

I'm a woman who has had her uterus, ovaries and Fallopian tubes removed coz of life-threatening disease. But my vagina, labia, clit, urethra and breasts remain, as do all the other parts of my body which bear the unmistakable stamp of my female sex - such as my pelvis; my post-menopausal pelvic floor issues; the stretch marks, hemorrhoids and pudendal neuralgia I have left over from pregnancy and childbirth 30 years ago; my female-sized heart and lungs; my female-functioning kidneys and immune system; and every cell in my body, which all carry my XX sex chromosome.

Males who get their dicks and testes removed/reconfigured coz they want to mimic women, as well as all the men who lose their penises and testes due to accidents, warfare and explosions, still retain a number of crucial internal male organs such as the prostate. And their male sex is still encoded in every cell of every organ in their bodies.

Male and female mean plants, animals and persons that evolution has determined will develop the anatomy to give them the potential capacity to produce sperm or ova at particular points in their lives after they've matured. Many male plants like trees produce sperm - pollen - only at certain times of the year, which is why humans have seasonal pollen allergies. But these plants are male all the rest of the time they're not producing pollen. Similarly, many sexually mature female mammals only produce ova at a given time each year - but they're still female all the rest of the time.

In any sexually-reproducing species, there will be organisms of either sex who for one reason or the other are incapable of producing sperm or ova at any time even after they mature. But they still are either of the female or male sex, and can be easily sexed.

Your mother, grandmother, aunts, great aunts all are probably post-menopausal and thus no longer have viable eggs and therefore can't reproduce. Some of these women might have had various surgeries to remove certain of their female organs due to health conditions. Please go tell them that in your condescending opinion they are no longer women. And get back to us with their reactions. We'll be waiting with bated breath.
