Estrogen levels will continue to increase for several days (on average, six days, but this varies widely). [7] These high estrogen levels initiate the formation of a new layer of endometrium in the uterus, histologically identified as the proliferative endometrium.
Ovulation occurs ~35 hours after the beginning of the LH surge or ~10 hours following the LH surge. Several days after ovulation, the increasing amount of estrogen produced by the corpus luteum may cause one or two days of fertile cervical mucus, lower basal body temperatures, or both. This is known as a "secondary estrogen surge". [4]
Menstrual cycle The menstrual cycle is a series of natural changes in hormone production and the structures of the uterus and ovaries of the female reproductive system that makes pregnancy possible.

Estrogen peaks at about 11 am on the day of proestrus. Between then and midnight there is a surge in progesterone, luteinizing hormone and follicle-stimulating hormone, and ovulation occurs at about 4 am on the next estrus day. The following day, metestrus, is called early diestrus or diestrus I.

A dosage of two to six 100 μg/day transdermal estradiol patches can achieve mean levels of estradiol in the area of 200 to 400 pg/mL and can be used as a form of high-dose estrogen therapy, for instance to suppress testosterone levels in the treatment of prostate cancer in men and in feminizing hormone therapy for transgender women.
