In the early stages of pregnancy, all foetuses (or however it's spelt) are female, and some believe that a problem in one or both of those doses of testosterone may be a contributing factor in people born to be transgender, or even possibly men who are extremely feminine.

In the early stages, every fetus (the modernized American spelling) looks similar, but they are not all female. Gender is actually determined by the sperm. Females have two X chromosomes, males have an X and a Y. The mother can contribute only an X chromosome; the father can contribute either X or Y. If it is a Y, the baby will be male. There are, of course, genetic abnormalities which can cause one parent to contribute more than one sex chromosome, but that's another story. The idea that all start out as female stems from the fact that before differentiation is complete, they look similar.
At even earlier stages, they all look like a brine shrimp - good thing women don't have to go home and announce that they gave birth to seafood.
FWIW, my left ring finger is longer than the index, right ring finger shorter than index, size 13 shoes, born right on schedule, statistically completely average cock, and I am gay. (I also hate to shop, have less than zero decorating sense, and would rather rebuild a car engine than go to a nightclub.)
P. S. As for testosterone injections - for anyone who has not completely finished maturing physically, hormone supplementation can be extremely dangerous, unless there is already some underlying pathology such as undeveloped testes. It can cause skeletal abnormalities and massive damage to internal organs, especially the liver and heart.
