Normal value of pgn, doctor explains the relationship between pgn, menstruation and pregnancy

The normal value of pgn is mainly used to determine the progesterone level in women and diagnose gynecological endocrine diseases.

The reference range of normal pgn values ​​is as follows: for non-pregnant women, the follicular phase (early) (0.7±0.1) μg/L, the follicular phase (late) (0.4±0.1) μg/L, the ovulatory phase (1.6±0.2) μg/L, the luteal phase (early) (11.6±1.5) μg/L, and the luteal phase (late) (5.7±1.1) μg/L.

PGN refers to progesterone, which is the main progestogen and works synergistically with estrogen to form the menstrual cycle. Increased progesterone can be seen in congenital adrenal hyperplasia, ovarian tumors, hydatidiform mole, etc. Decreased progesterone can lead to miscarriage, amenorrhea-galactorrhea syndrome, etc.
