lately i have often notice people posting?

responses to questions that state all fetuses start out female, and later on the y chromosome develops and the sex of the baby becomes male.

now it has been 7yr since i last was pregnant, but i believe, i remember reading that from the moment of conception the baby has a pacific sex. it is just in till the sex organs actually develop, fetuses look male because of the collection of tissue that will develop in to the penis or vagina, (i believe i have been told that the head of the penis and the clitoris are actually the same, i could be wrong on that one)

so i guess my question is, are all fetuses female from the beginning or is that just and old myth, and are fetuses what ever sex they are suppose to be from conception?

i hope this is the best category for this question. the suggested category was Lesbian, Gay, Bisexual, and Transgendered
