Progesterone is produced mainly by the ovaries after ovulation and supports pregnancy and menstrual regulation.

Diagnostic Value: Progesterone testing confirms ovulation and assesses luteal phase sufficiency. Low levels may cause infertility or recurrent miscarriage, while high levels may indicate pregnancy or ovarian cysts.

Clinical Importance: It is essential in evaluating irregular cycles, unexplained infertility, and menopausal hormone balance.

Symptom Correlation: Deficiency may lead to mood swings, spotting, sleep disturbances, and anxiety.

Progesterone testing helps assess reproductive stability and hormonal harmony essential for conception and menstrual health.
