The human female reproductive system is made up of the internal and external sex organs that function in the reproduction of new offspring. The reproductive system is immature at birth and develops at puberty to be able to release matured ova from the ovaries , facilitate their fertilization , and create a protective environment for the ...
The ova, which are the female sex cells, are much larger than the spermatozoon and are normally formed within the ovaries of the female fetus before birth. They are mostly fixed in location within the ovary until their transit to the uterus, and contain nutrients for the later zygote and embryo .

After completion (or abortion) of a pregnancy, some species have postpartum estrus, which is ovulation and corpus luteum production that occurs immediately following the birth of the young. [14] For example, the mouse has a fertile postpartum estrus that occurs 14 to 24 hours following parturition.
Before puberty, humans are naturally infertile; their gonads have not yet developed the gametes required to reproduce: boys' testicles have not developed the sperm cells required to impregnate a female; girls have not begun the process of ovulation which activates the fertility of their egg cells (ovulation is confirmed by the first menstrual ...
A 'neo-vagina' can be constructed for those girls and women who do not have a vagina. [42] [43] Vaginal septa are treated surgically. [44] [45] The most common vaginal anomaly is an imperforate hymen. This anomaly occurs often enough that it can be detected by some pediatricians shortly after birth.
Sterility is the inability to produce a biological child, while infertility is the inability to conceive after a certain period. [1] Sterility is rarely discussed in clinical literature and is often used synonymously with infertility. Infertility affects about 12-15% of couples globally. [2] Still, the prevalence of sterility remains unknown.
