Ovary: Luteal Stage
After ovulation happens, the fresh hair follicle that contains the latest egg converts to the things called a corpus luteum and begins to create progesterone and estrogen (ten,13). Progesterone account height from the halfway through this phase (14). The new hormonal alterations of the luteal stage is actually of the common premenstrual periods that many anybody experience, such as for instance aura transform, stresses, places, bloating, and you may breast inflammation.
If an egg try fertilized, progesterone regarding the corpus luteum supporting the first pregnancy (15). In the event the no fertilization occurs, the latest corpus luteum will start to falter ranging from nine and you can eleven months after ovulation (10). So it results in a drop during the the hormone estrogen and you will progesterone accounts, which causes menstruation.

The most known ones messengers is the prostaglandins, being produced of the endometrial tissue and trigger changes with other structure nearby.
Several prostaglandins in particular called, “PGF2?” and you will “PGE2”, cause the uterine muscle tissue to help you offer (cramp). The fresh new levels of this type of prostaglandins increase once ovulation and you will arrived at the peak throughout durations (16,17). The newest cramping due to which prostaglandin assists trigger that time. When the a pregnancy takes place, prostaglandin production was restricted (18) to Recommended Reading make certain that this type of contractions wouldn’t effect an early on maternity. If the maternity doesn’t exist, the new corpus luteum stops producing estrogen and you will progesterone.
