Welcome to the Primate Reproductive Ecology and Evolution group at NYU. The genus Alouatta is one of the most difficult New World monkeys to breed and rear in captivity. It also causes female reproductive organs to grow. Old world monkey- most of leaf monkeys, langurs, family presbytis, macaques. The anatomical relationship between the vagina, uterus, broad ligament, oviducts and ovaries are those of a typical primate reproductive tract. The secondary sex organs are the epididymis, vas deferens and penis. Author information: (1)Reproductive Endocrinology Center, University of California, School of Medicine, San Francisco 94143-0556.

With the exception of the Celebes Macaque, females mature much earlier than males. Organs of the female reproductive system. Alouatta guariba clamitans (brown howler monkey) is an endemic primate from the southeastern Brazil tropical forests, classified as near threatened by the IUCN Red List 2007. The vulva includes the mons pubis (or mons veneris), labia majora , labia minora , clitoris , vestibular bulbs , vulval vestibule , urinary meatus , the vaginal opening , hymen , and Bartholin's and Skene's vestibular glands . Polyandry: (rare in primates) New world monkey only- some of the callitrichids are "facultatively" polyandrous. A lot. In this study we examined the macroscopic and histological aspects of the female genital tract of wild brown howler monkeys to provide baseline information for future reproduction research. The reproductive tract of the bull consists of the testicles, secondary sex organs, and three accessory sex glands. Thind KK(1), Boggan JE, Goldsmith PC. Macaques reach sexual maturity around 3-4 years although they often don’t start breeding until they’re older (males around 8 – females around 5). Antral follicle, monkey, epon, 150x. Apes- chimps. Promiscuity: New world monkey- marikis. The menstrual cycle of Macaques will occur every 28-31 days (34-36 in Celebus Macaques). Ape- gorilla. Her clitoris, which contains the birthing canal, protrudes 7 inches from her body. These organs work in concert for formation, maturation and transport of spermatozoa, which are eventually deposited in the female reproductive tract. Higher magnification reveals the developing corona radiata, the ring of follicular cells that remains attached to the ovum even after ovulation and the cumulus oophorus, the stalk of follicular cells that attaches the ovum to the follicle. In this study we examined the macroscopic and histological aspects of the female genital tract of wild brown howler … In the young spider monkey Ateles, the clitoris is six or seven centimetres (2.4 to 2.8 inches) long.
