What should I know about progesteronmangel symptome?

Progesterone deficiency commonly presents with menstrual irregularities (short cycles, spotting), premenstrual syndrome (PMS), sleep disturbances, mood swings, and fluid retention. In the luteal phase, low progesterone can impair endometrial maturation, leading to infertility or early pregnancy loss. Other symptoms include headaches, breast tenderness, and low libido. Diagnosis requires a blood test on day 21–23 of a 28‑day cycle. Symptoms are non‑specific and may overlap with thyroid disorders, stress, or other hormonal imbalances. The provided context does not contain specific information on progesterone deficiency; this answer is based on general clinical knowledge. A healthcare provider should evaluate symptoms and order appropriate lab work. Evidence grade: practice (clinical consensus), no direct sources from context.
