Cristina Algarra, psychologist specialized in assisted reproduction for InviTRA, explains in this video what are the probable causes of the appearance of ovarian cysts:
Ovarian cysts appear during the normal functioning of the ovaries, during the ovulation. These cysts are called functional cysts we can distinguish two main ones:
First we have follicular cysts, these cysts form when there is a malfunction of the release of the egg, the egg doesn´t properly release, forming a cyst. This cyst can be up to 2.5 cm and it reabsorbs. 2-3 menstrual cycles.
Then we can find corpus luteum cysts, these cysts form once the egg has exited the follicle, the empty follicle is filled with fluid again creating a cyst. These cysts are a little bigger, they can be up to 3 cm and they reabsorb in about 2-3 weeks.
