Progesterone is an important hormone in the female body, which plays a crucial role in the process of conception and pregnancy. If pregnant women have low progesterone, it is easy to cause threatened miscarriage. If the progesterone level is low in non pregnant women, it can reduce the chances of conception and even cause infertility. So, what is the normal value of progesterone before pregnancy?
When a woman is not pregnant, progesterone in the body will undergo some changes at different stages of the physiological cycle, such as the normal value of 0.2-0.9ng/ml during the follicular phase, 1.16-3.13ng/ml during the pre ovulation phase, and 6.1-32ng/L during the ovulation phase. If it is in the luteal phase, the normal value of progesterone is ≥ 15ng/ml.
Before a female friend becomes pregnant, the highest level of progesterone during the entire menstrual cycle is 0.5-20ng/ml. Due to the fact that progesterone levels in non pregnant women can vary depending on different physiological stages, in order to know the specific value, one should first consider which stage of their menstrual cycle they are in.
If a woman intends to conceive, it is best to undergo a period of preconception preparation and go to the hospital for a physical examination, such as hormone testing, which includes progesterone testing to determine if her progesterone is normal. Regardless of whether a woman is pregnant or not, if there is a low progesterone level, it is generally caused by insufficient luteal function.
