Detailed explanation-1: -As the follicle grows, blood levels of estrogen rise significantly by cycle day seven. This increase in estrogen begins to inhibit the secretion of FSH. The fall in FSH allows smaller follicles to die off.
Detailed explanation-2: -Thus, with combined oral contraceptives, constant and high levels of estrogens and progesterone not only inhibit the LH peak, but also decrease the basal LH-FSH levels and responses to releasing hormone.
Detailed explanation-3: -Oestrogen is a female sex hormone produced by follicles in the ovaries. The most important job of oestrogen is to regulate the menstrual cycle. It makes the lining of the uterus – the endometrium – thicker and more receptive to a fertilised egg. Oestrogen peaks just before ovulation.
