Answer:
The menstrual cycle is the regular natural change that occurs in the female reproductive system (specifically the uterus and ovaries) that makes pregnancy possible.The cycle is required for the production of oocytes, and for the preparation of the uterus for pregnancy.The menstrual cycle occurs due to the rise and fall of estrogen.This cycle results in the thickening of the lining of the uterus, and the growth of an egg, (which is required for pregnancy). The egg is released from an ovary around day fourteen in the cycle; the thickened lining of the uterus provides nutrients to an embryo after implantation
The organ responsible for the production of an ovum in primate females. In humans a set of two ovaries is present and they are both functional. They are mainly involved in gamete formation and hormone secretion. Normally, ovaries produce one ovum per month or per menstrual cycle. They are involved in the secretion of secrete estrogen, testosterone, inhibin, and progesterone. These hormones are responsible for secondary sexual characteristics in females and for the maturation and maintenance of the female reproductive organs. The menstrual cycle is the periodic process of ovulation in female primates that also involves menstruation. It is a cyclic process and is divided into four phases- the follicular phase, the ovulatory phase, the luteal phase, and the menstrual phase. It is this cycle that makes pregnancy in females possible. It is mainly controlled and affected by hormones like the luteinizing hormone, progesterone, and estrogen.
