The menstrual cycle is the female reproductive cycle marked by cyclical changes in the uterine lining.
Gonadotropins, which are released by the anterior pituitary gland, control the menstrual cycle (FSH and LH).
FSH promotes Graafian follicle growth, development, and hormone release, as well as ovum maturation.
LH stimulates Graafian follicle development, and an LH spike between 12 and 14 days of the cycle causes Graafian follicle rupture and ovum release, i.e. ovulation.
Gonadotropins also encourage growing follicles to release progesterone and oestrogen, which prepares the uterus for implantation and exerts negative feedback control on gonadotropin production following ovulation.
Final Answer
Hence, this is the explanation of the menstrual cycle.
