The male fetus produces larger amounts of androgens and smaller amounts of estrogens than a female fetus. This difference in the relative amounts of these sex steroids is largely responsible for the physiological differences that distinguish men from women. During puberty, hormones which stimulate androgen production result in the development of secondary sexual characteristics , thus exhibiting greater differences between the sexes. However, there are exceptions to the above for some transgender and intersex men. The Old English form had a default meaning of "adult male" which was the exclusive meaning of wer , though it could also signify a person of unspecified gender. The closely related Old English pronoun man was used just as it is in Modern German to designate "one" e. In human beings, the sex of an individual is determined at the time of fertilization by the genetic material carried in the sperm cell.
List of related male and female reproductive organs
The human reproductive system usually involves internal fertilization by sexual intercourse. In this process, the male inserts his penis into the female 's vagina and ejaculates semen , which contains sperm. A small proportion of the sperm pass through the cervix into the uterus, and then into the Fallopian tubes for fertilization of the ovum. Only one sperm is required to fertilize the ovum.
The female reproductive system is made up of the internal and external sex organs that function in reproduction of new offspring. In the human the female reproductive system is immature at birth and develops to maturity at puberty to be able to produce gametes , and to carry a foetus to full term. The internal sex organs are the uterus , Fallopian tubes , and ovaries. The uterus or womb accommodates the embryo which develops into the foetus. The uterus also produces vaginal and uterine secretions which help the transit of sperm to the Fallopian tubes.
