- The reproductive cycle of female primates is called the menstrual cycle. Menstrual cycle starts only after attaining sexual maturation (puberty). Generally, during ovu lation only one ovum is released per menstrual cycle. The cyclical changes in the ovary and the uterus during menstrual cycle are induced by changes in the levels of pituitary and ovarian hormones. After coitus, sperms are transported to the junction of the isthmus and ampulla, where the sperm fertilises the ovum leading to formation of a diploid zygote.

Female Reproductive System
The female reproductive system provides various functions. The ovaries produce the egg cells known as the ova or oocytes. The oocytes are then taken to the fallopian tube where fertilization by a sperm may occur. The fertilized egg is then transferred to the uterus, where the uterine lining has thickened in regard to the normal hormones of the reproductive cycle. Once in the uterus, the fertilized egg can implant into the thickened uterine lining and continues to develop. If implantation does not take place, the uterine lining is shed as menstrual flow. In addition, the female reproductive system produces female sex hormones that preserve the reproductive cycle.
During menopause, the female reproductive system slowly stops making the female hormones that are required for the reproductive cycle work. At this stage, menstrual cycles can become irregular and finally stops. One year after menstrual cycles pause, the woman is deemed to be menopausal.
