  2. Gonad - Wikipedia

    en.wikipedia.org/wiki/Gonad

    A gonad, sex gland, or reproductive gland [1] is a mixed gland and sex organ that produces the gametes and sex hormones of an organism. Female reproductive cells are egg cells, and male reproductive cells are sperm. [2] The male gonad, the testicle, produces sperm in the form of spermatozoa. The female gonad, the ovary, produces egg cells

  3. Heterocrine gland - Wikipedia

    en.wikipedia.org/wiki/Heterocrine_gland

    In females, Ovaries produce estrogen and progesterone, which regulate the menstrual cycle, control the development of female secondary sexual characteristics, and support pregnancy. Exocrine function: Gonads release substances through ducts. In males, Testes release sperm through the vas deferens, which is part of the reproductive system.

  4. Sexual characteristics - Wikipedia

    en.wikipedia.org/wiki/Sexual_characteristics

    In invertebrates and plants, hermaphrodites (which have both male and female reproductive organs either at the same time or during their life cycle) are common, and in many cases, the norm. In other varieties of multicellular life (e.g. the fungi division, Basidiomycota ), sexual characteristics can be much more complex, and may involve many ...

  5. Reproductive system - Wikipedia

    en.wikipedia.org/wiki/Reproductive_system

    The human female reproductive system is a series of organs primarily located inside of the body and around the pelvic region of a female that contribute towards the reproductive process. The human female reproductive system contains three main parts: the vulva , which leads to the vagina, the vaginal opening, to the uterus; the uterus , which ...

  6. Female reproductive system - Wikipedia

    en.wikipedia.org/wiki/Female_reproductive_system

    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 ...

  7. Ovary - Wikipedia

    en.wikipedia.org/wiki/Ovary

    Birds have only one functional ovary (the left), while the other remains vestigial. In mammals including humans, the female ovary is homologous to the male testicle, in that they are both gonads and endocrine glands. Ovaries of some kind are found in the female reproductive system of many invertebrates that employ sexual reproduction. However ...

  8. List of related male and female reproductive organs - Wikipedia

    en.wikipedia.org/wiki/List_of_related_male_and...

    This list of related male and female reproductive organs shows how the male and female reproductive organs and the development of the reproductive system are related, sharing a common developmental path. This makes them biological homologues. These organs differentiate into the respective sex organs in males and females.

  9. Sexual differentiation in humans - Wikipedia

    en.wikipedia.org/wiki/Sexual_differentiation_in...

    In both males and females, the sex organs consist of two structures: the internal genitalia and the external genitalia. In males, the gonads are the testicles and in females, they are the ovaries. These are the organs that produce gametes (egg and sperm), the reproductive cells that will eventually meet to form the fertilized egg .
