Many patients believe that the ovaries alternate in their ovulatory function in an orderly manner. One month the right ovary ovulates and the next month the left ovary ovulates. The reality is that both ovaries work simultaneously, sometimes both ovaries can ovulate, and most of the time it is the largest follicle that breaks away, but this does not follow any order. In fact, it is not uncommon for one ovary to ovulate more frequently, and obviously after a surgical procedure to remove one ovary, patients do not skip ovulation because the remaining ovary always ovulates since the other one is not there to compete with it.<\/p>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

It is a widespread false belief that ONE EGG is usually used with each ovulation. The reality is that it is one or at most two eggs that manage to leave the ovary each month to reach the tube, but dozens of follicles from both ovaries compete each month (antral follicles), and hundreds or thousands of (primordial) oocytes do not even compete and are also lost every month.<\/p>\n

It is estimated that from before birth until menopause, a woman uses between 500 and 2000 eggs each month regardless of whether she ovulates or not. Therefore, having the first period at a young age, having taken the contraception pill, having had few periods, having undergone ovarian stimulation treatments, etc. does not change the monthly loss of eggs, it only changes the number of eggs that have managed to leave the ovary. Throughout a woman\u2019s life, more than 500 eggs are not usually ovulated outside the ovary, but she uses several million eggs during that period of time until menopause.<\/p>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

The term polycystic ovaries indicates the presence of more than 12 small follicles spread across the cortex of one or both ovaries. In other women, the distribution of follicles is usually spread more evenly throughout the ovary.
Having polycystic ovaries and having polycystic ovary syndrome is not the same thing. Many women have polycystic ovaries, which means that their number of follicles is higher than usual, but in these cases there are usually no fertility problems.
However, polycystic ovary syndrome (PCOS), which is a hormonal disorder affecting 10-15% of all women of reproductive age, is (sometimes) associated with fertility problems.
Women with PCOS have high levels of hormones called androgens (a male hormone found in small amounts in women), characterised by the presence of at least 2 of the following 3 criteria:<\/p>\n
