Throughout the menstrual cycle, the level of LH in the body rises and falls. When the LH concentration surges, the dominant follicle ruptures and releases a mature egg from the ovary. Ovulation occurs 24 to 36 hours after the LH surge. After ovulation, the egg can live for up to 24 hours and sperm can survive in the uterus for three to five days.
Did anyone do some research on this topic? I assume that the hormone level in space is lower and that the ovarian reserve and primordial follicles are also being affected by microgravity and space radiation.

The ovulation has other components including maturation of the follicle and oocyte,preovulatory estradiol surge etc. A new paper from Russia published just this summer reporting ovulation in 1 astronaut during spaceflight.
