Ovarian and menstrual cycles by dr Khaled A Abulfadle

There is cyclic changes in ovaries, uterus, cervix, vagina, vulva (external genitalia) and breast. These cyclic changes in these areas occur at same time


As you know the female cycle is 28 days from 1st day of menses and the female ovulates about the 14th day of the cycle.


Thus, we can divide the female cycle into two parts i.e. 1st half before ovulation which is under estrogen control and 2nd half after ovulation which is under progesterone control


Thus, there are cyclic changes in the vagina (vaginal cycle) under these hormonal cyclic changes e.g. there is increased acidity and secretions in the vagina under progesterone control in the second half of the cycle

Also, there are cyclic changes in the cervix (cervical cycle) under those hormonal cyclic changes e.g. cervical secretions during the second half of the cycle becomes viscid forming cervical mucous plug under progesterone control
