  • That’s admirable that you want to be able to respond to arguments in a more thoughtful way, and I’m sorry people were assuming otherwise. I can’t really condense the entire semester of my developmental biology class into a comment, but I tried to give you terms to explore and learn more about.

    I read the edit to your original comment and I think you’re on the right path!


  • The term that might help you is “oogenesis”.

    Essentially once cells have begun dividing following fertilization some are set apart as germ cells. These are the cells that eventually become gametes. The thing is, like I tried to mention in my last reply to that guy, it isn’t strictly chromosomes that determine what these cells become in humans. Lots of genetic transcription and translation factors, hormones and hormone receptors, ligands and so on are involved. Sometimes those cells don’t even make it into the gonad, they die, and are absorbed by the embryo’s body.

    This is why sex isn’t a binary, there is a spectrum of outcomes following gametogenesis, including a lack of gametes. Statistically it is most likely for a person who is born XX to have primary and secondary female sex characteristics. But that doesn’t mean people who fall outside of that aren’t also “biologically” women. If you define a woman as someone that is born with eggs, you deny womanhood to millions of people that would otherwise be considered a cis-woman by outdated standards.

    That person stated one argument and then kept changing it, eventually arguing that we just weren’t understanding his words. Either he’s willfully ignorant and pushing a definition that is not taught in American universities, or he has an agenda. And the refusal to acknowledge the 30+ comments telling him he is wrong really suggests that there is an agenda.

    I provided several examples of chromosome combinations that result in people who produce no gametes. You’ve said in several comments that no one is born with a body plan that doesnt produce gametes, and that is incorrect. I’m a biology major, and I’m in a developmental biology class right now There are several points in development that can cause a failure to develop a sexual phenotype.

    I don’t know why you’re saying it’s a hard line that biologists have drawn, when science is about being able to adjust our understanding of the world when we are presented with new information

    Edit: The body plan that you are talking about is a result of several things ranging from transcription factors to hormones working together, not just chromosomes alone. A break at any point can result in a body that isn’t “organized” (whatever you think you mean by that I don’t know) to produce gametes. I feel like you’re trying to play “gotcha!” throughout these comments and have no true understanding of biology. I recommend that you try going back to school

    XO, XX, XY, XXY, XYY, XXX, XXXX, XXXY, XXYY, and others have been recorded in humans. In addition there is Swyer syndrome, Chappell syndrome, and mosaicism in which the gonadal phenotype doesn’t match the genotype. There are also events during fertilization which can cause an XX zygote to gain the SRY gene from the father. The SRY gene is what initiates male gonad development.

    Sex is not binary just because there are two types of sex chromosomes. They can occur in multiple combinations and result in a spectrum of characteristics. Many of those combinations result in infertility, because they result in a loss of reproductive organs and/or indeterminate genitalia

    There are a few reasons that I know of: Heavy bodies are more difficult to move, fat bodies take longer to dissect, and large bodies don’t always fit on the (usually decades-old) tables.

    I think that weight is a disqualification that’s been changing in recent years, because even in Europe bodies are starting to trend larger. But it’s still something to keep in mind if you live in like Mississippi and think the University of Mississippi will take your 350 pound grandpa when he passes on.


  • I think it’s implying the opposite, that they abused their body so much during life that they no longer qualify to be donated. Weight is one of the major disqualifiers for whole-body donation.

    The vast majority of bodies go to medical institutions for surgical training, with a smaller percent going to research
