Progesterone ivf how much

Properly timed blood tests to measure progesterone levels may be done in the woman who has regular menses. A biopsy of the uterine lining may even be done although an uncommon practice these days to determine a lack of progesterone effect.

During the egg retrieval process, the cells that normally create progesterone after ovulation are removed along with the eggs. Progesterone supplements are then required to prepare the body for pregnancy and thicken the uterine lining to support successful embryo attachment in the womb.

Progesterone may also be required during the pregnancy to safeguard against pregnancy loss. Continuation of progesterone supplementation is advisable, on an individual basis, even up to 12 weeks of pregnancy in a cycle where embryo transfer is done. Depending of the route of administration, there may be no side effects, especially with vaginal preparations, which have a direct uterine effect, rather than a systemic one. Vaginal discharge or irritation are possible with these forms.

If injectable or oral preparations are used, side effects may include pain, swelling and bruising at the injection site, headaches, breast tenderness, drowsiness, dizziness, fluid retention, bloating, hot flashes, constipation, and everything that mimics pregnancy symptoms!

These symptoms may persist into a pregnancy as well, or stop when the drug is withdrawn. Natural progesterone, which is used during fertility treatment, poses no threat to a mother and child. It is important to note that the Food and Drug Administration FDA does not differentiate between natural progesterone and synthetic progesterone progestins in its warnings.

Progestins are mostly used to suppress ovulation and are found in birth control pills. Freezing embryos created during IVF before transferring them back to the patient has become increasingly common as freezing techniques have improved. Tests to examine embryos for chromosomal or genetic diseases are also becoming more widely used, and these often require freezing.

But physicians have been unsure whether transferring frozen embryos changed pregnancy rates. Until now, only small studies have been done, and some have been inconclusive. To compare success rates of transferring fresh versus frozen embryos, Wang and her colleagues used a large database maintained by Celmatix that contains records of hundreds of thousands of IVF treatments performed at 12 fertility treatment centers in the United States.

From the database, two cohorts of 1, IVF transfers were selected to study: one group in which all the embryos were frozen before transfer, and another group in which fresh embryos were transferred. Patients in the two cohorts had similar ages, causes of infertility, reproductive histories, numbers of eggs retrieved, number of embryos created and levels of reproductive hormones. Fifty-two percent of the embryo transfers performed after embryos were frozen led to ongoing pregnancies, whereas After analyzing all IVF transfers together, the researchers performed separate comparisons of women with lower and higher progesterone levels, as well as of women who were younger and older than Women with lower progesterone levels who received previously frozen embryos did not experience better pregnancy outcomes, regardless of their age.
