How does progesterone withdrawal work?

In the absence of pregnancy, typical progesterone withdrawal bleeding occurs following ovulation. Endometrial desquamation is also caused by the removal of the corpus luteum. A comparable outcome can be induced pharmacologically by administering and then discontinuing progesterone or a synthetic progestin. Withdrawal bleeding usually begins within a few days of stopping the hormone treatment and may last for several weeks.

Withdrawal bleeding can be difficult to predict because it depends on how long you were on the hormones, what dose you were taking, and whether you withdrew completely from both pills and injections. The best way to avoid heavy bleeding when withdrawing from birth control pills is to begin timing your period about three months before you intend to stop taking them. The same thing goes for those who are injecting progesterone: Stop injecting at least four weeks before you want to start your period and time your period like you would if you were trying to avoid pregnancy. Heavy bleeding often stops around the time your period is due to begin.

If you do not plan to get pregnant again soon, there is no need to withdraw completely from birth control pills or injections. You can continue taking them as usual while still having your period come every month. This method uses up your supply of hormones more slowly than withdrawal but will still protect you from getting pregnant until you finish what's left of the bottle or injection kit. Women who are thinking of becoming pregnant should not use birth control pills or injections.

What happens to the uterine lining when progesterone levels drop?

If the egg is not fertilized and no embryo is formed, the corpus luteum degrades and progesterone production diminishes. When the uterine lining is no longer maintained by progesterone from the corpus luteum, it ruptures and monthly bleeding ensues, signaling the start of a new menstrual cycle. At this time, the endometrium (the lining of the uterus) will be completely regenerated by cell division.

If the egg does become fertilized and a blastocyst forms, the corpus luteum will continue to produce progesterone until it fails. At this time, the body will switch to producing estrogen instead, causing the uterine lining to shed its old cells and grow new ones. By switching back and forth between progesterone and estrogen, the body maintains a relatively stable balance between these two hormones. If no pregnancy occurs, the process starts over again when the next LH surge causes the ovary to release another egg. This ongoing process is what keeps women's bodies ready for pregnancy every month.

As mentioned, if a woman doesn't get pregnant within 12 months, her body will stop making sperm and start making eggs less frequently. Her fertility eventually declines to zero and she becomes post-menopausal. However, if a woman does conceive during those 12 months, her body will continue making eggs even after the baby is born.

What happens to your body when you stop taking progesterone?

Taking progesterone also does not "restart" your period. It can induce a bleed because your body detects a dip in progesterone when you stop taking it (more on that in Part 1 of this series), but it does not affect the normal hormone levels that cause a menstrual cycle to begin.

It stimulates the uterine membrane to thicken in preparation for receiving a fertilized egg. If the egg is not fertilized, the corpus luteum degenerates and ceases releasing progesterone. During a typical menstrual cycle, this happens once a month. If the egg is fertilized, human chorionic gonadotropin is produced (hCG).

What happens in the uterine cycle when estradiol and progesterone start to decrease?

Estradiol and progesterone levels fall as the menstrual cycle begins. Because of the decline in hormone levels, the endometrial layer sheds, resulting in monthly bleeding. During menstruation, the amount of follicle-stimulating hormone (FSH) rises, encouraging the development of numerous ovarian follicles. As more and more follicles mature, the body produces higher and higher amounts of FSH so that all the available follicles will matures at once.

Menopause occurs when a woman lacks estrogen for a long period of time. The drop in estrogen levels causes the endometrium to thin out, which can lead to problems with heavy bleeding or even miscarriage. Women who have had their ovaries removed still receive estrogen through other means; therefore they will also experience a loss of endometrial tissue and be postmenopausal. Menopause is not just an issue for women; it also affects men who share their environment with women of childbearing age. For example, if a man reaches age 70 without having been diagnosed with cancer, he is likely healthy. However, if he also reaches age 70 without having had any children, then he has doubled his risk of dying over the next 10 years. This is because the lack of estrogen causes arteries to tighten, reducing blood flow to the heart and other organs. In addition, testosterone levels drop after puberty until death, causing bone density to decrease too.
