Low progesterone and sperm quality do not have a very direct relationship, low progesterone does not mean that the child will definitely be miscarried, or the child has some kind of deformity risk, this statement is unscientific, because the hormone levels in the body of each woman, the basal value may vary. Some women may have a high range of progesterone during pregnancy, and even if the progesterone is high and there are some symptoms of preeclampsia such as vaginal bleeding and lower abdominal pain, they still need to be treated with progesterone or proprietary birth control medication under the direction of a doctor. Some women’s hormone levels are very low, progesterone may not be particularly high during pregnancy, about a dozen, but the pregnancy has been particularly stable, no bleeding, lower abdominal pain symptoms, also do not need special treatment, regular birth control can be. Therefore, low progesterone does not mean that you will have a miscarriage, and it is not very, very closely related to sperm quality.
