Female cattle, also referred to as "heifers" in agriculture, will gradually enter standing estrus, or "standing heat," starting at puberty between 9 and 15 months of age. The cow estrous cycle typically lasts 21 days. [5] Standing estrus is a visual cue which signifies sexual receptivity for mounting by male cattle.
A freemartin or free-martin (sometimes martin heifer) is an infertile cow with masculinized behavior and non-functioning ovaries. [1] Phenotypically, the animal appears female, but various aspects of female reproductive development are altered due to acquisition of anti-Müllerian hormone from the male twin. [2]
Udder of a cow. An udder is an organ formed of two or four mammary glands on the females of dairy animals and ruminants such as cattle, goats, and sheep. [1] An udder is equivalent to the breast in primates, elephantine pachyderms and other mammals.

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 ratio of male to female offspring at birth is approximately 52:48. [15] A cow's udder has two pairs of mammary glands or teats. [16] Farms often use artificial insemination, the artificial deposition of semen in the female's genital tract; this allows farmers to choose from a wide range of bulls to breed their cattle.
The uterine horns (cornua of uterus) are the points in the upper uterus where the fallopian tubes or oviducts exit to meet the ovaries.They are one of the points of attachment for the round ligament of uterus (the other being the mons pubis).
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.
