I think there are risks to other people when it comes to transplanted penises, because men who want transplanted uteruses plan on being "pregnant" right? Women who want transplanted penises would also want to make women "pregnant", to say to people "we are real men". If a female with a transplanted penis uses the "sperm" produced from transplanted testes to reach the "egg" from transplanted ovaries in a male, then that would mean someone else (the fetus) is being affected. I think there should be more articles like that first one, but this time arguing against penis transplants, it's sad people aren't thinking about the risky things women can do with transplanted penises :(

If a female with a transplanted penis uses the "sperm" produced from transplanted testes to reach the "egg" from transplanted ovaries in a male,

A lot more than the penis and testes would have to be transplanted for this to occur. Sperm is made in the testes, but for sperm to make its way from the testes through and out the penis requires the contribution of various fluids from other male organs, such as the prostate. Seminal fluid/male ejaculate contains sperm, but is much more than sperm.

Similarly, it would take more than a transplanted uterus and ovaries for a male to become pregnant. Conception of a human egg typically occurs in the Fallopian tubes, then the fertilized egg passes into the uterus.

There the fertilized egg has to become implanted in the endometrium lining the uterus to have a chance at being viable. For a pregnancy to occur, an entirely new organ - the placenta - has to grow to supply the embryo/fetus with blood and nutrients. The instructions for implantation and placenta development to occur come from having female sex chromosomes - aka the "software" - not simply from having transplanted female body parts - aka "hardware."

Beyond those events, there are many, many things that have to occur in a female body to sustain a pregnancy and grow a fetus to the point it can live outside the mother's womb. Female kidneys have been shown to function differently to male kidneys; female kidneys appear to have evolved to handle the much greater fluid volume and cleansing burden that pregnancy entails. It's unlikely that a male's kidneys could handle the extra load of a pregnancy. The differences in male and human kidney function seem to account for the fact that whilst kidney disease is more common in women than men, men die of kidney disease at much higher rates and at earlier ages than women do.

Male and female humans also have different levels of immune function, which stems from the fact that immune function is on the X chromosome - of which males have only one. By contrast, females have two X chromosomes - and when one fails, the other previously inactive or "silent" X chromosome becomes activated and kicks in. This is obviously beneficial in protecting a pregnant woman's health and the health of her embryo/fetus. No way males with their XY chromosomes could pull off such a feat.
