    2.FSG (follicle stimulating hormone) - on 3-5 day of the cycle. FSH has a trophic effect on the ovary, stimulates the growth, development and maturation of the follicle.

    3.Prolactinum - on the 3-5 day of the cycle. Has a trophic effect on the yellow body, turns it from non-functioning to functioning. Thus, the secretion of progesterone is stimulated. Stimulates lactation and suppresses the secretion of FSH; for this reason the follicle does not develop.
