Although progesterone is necessary (though not absolutely necessary) for the maintenance of pregnancy, it is not well recognized how little progesterone is truly needed. According to our observations, progesterone is given much too much attention.
We are responsible for a portion of this. I’m referring to the Reproductive Endocrinology Community (REI) Reproductive endocrinologists (REI) used to write articles and chapters in Ob/Gyn textbooks claiming that progesterone levels of 10 ng/ml were indicative of high-quality ovulation. The norm of progesterone during pregnancy Since this figure was simple to recall, it has been handed down through the ranks of Ob/Gyns in training and has practically become “common knowledge” in the field.
role of progesterone in the treatment of patients who have recurrent pregnancy loss?
Only a delay in the diagnosis of miscarriage has been shown with progesterone supplements, not a reduction in the likelihood of loss. To put it another way, a pregnancy may stop developing, but the progesterone we provide can make the miscarriage seem to be normal.
That being said, just though studies have not demonstrated that progesterone may prevent the loss, it does not rule out the possibility that there is a woman who might benefit from taking it. Giving progesterone to many hundred women at a time may be necessary to avoid a single loss of fertility. Because progesterone has no known detrimental effects on pregnancy, and because it is very inexpensive. The patient will never have to wonder what would have occurred if they had taken progesterone instead of estrogenic.
How long should my progesterone levels be monitored when I’m expecting a child?
It is virtually always unnecessary to do further progesterone measures as soon as a heartbeat has been detected. As early as five weeks and six days after conception, the heartbeat may be detected. In natural pregnancies, the placenta will produce all of the progesterone required for a woman to remain pregnant by the time she is seven weeks pregnant. There is no greater risk of miscarriage even if the ovaries are removed and all progesterone is stopped in the women. What evidence do we have to support this? This has been shown in studies that have been conducted!
For our IVF patients, we usually provide progesterone until they are around eight weeks pregnant, one week beyond this key week. If a patient wants to remain on the list for an extended period of time, that is great. While it is unlikely to do any damage, doing so is not necessary.
It is futile to measure progesterone levels at this point in time. If the placenta is unable to produce enough at this stage, the placenta will not be able to maintain the pregnancy and the patient may miscarry as a result.
