🧪 What is the Progesterone Test?

Progesterone is a steroid hormone produced mainly by the corpus luteum in the ovary after ovulation, and by the placenta during pregnancy. It plays a key role in:

Preparing the endometrium for implantation
Maintaining early pregnancy
Regulating the menstrual cycle

❓ Why is the Test Done?

To:

Confirm ovulation in infertility evaluation
Assess corpus luteum function
Monitor early pregnancy viability
Diagnose causes of abnormal uterine bleeding
Evaluate risk of miscarriage
Guide assisted reproductive techniques (ART)

📊 Normal Range (varies with menstrual cycle phase)

Phase	Progesterone Level (ng/mL)
Follicular phase	< 1.5 ng/mL
Ovulation (mid-cycle peak)	5 – 20 ng/mL
Luteal phase	5 – 20 ng/mL
Early pregnancy (1st trimester)	11.2 – 90 ng/mL
Postmenopausal	< 0.2 ng/mL

📈 Interpretation of Results

Progesterone Level	Meaning
Low (<5 ng/mL mid-luteal)	Anovulation or luteal phase defect
Elevated during pregnancy	Normal pregnancy maintenance
Very low in pregnancy	Possible miscarriage or ectopic pregnancy
Low post-ovulation	Infertility or ovulatory dysfunction

🧠 Associated Organs & Conditions

Organ/System	Conditions
Ovaries	Ovulatory dysfunction, corpus luteum insufficiency
Uterus	Endometrial disorders, implantation failure
Placenta	Early pregnancy support
Pituitary/Adrenal	Secondary hormonal imbalances affecting progesterone

🔄 Related / Follow-Up Tests

LH and FSH – assess ovulatory status
Estradiol – ovarian function
Beta hCG – confirm pregnancy
Ultrasound – follicle tracking and pregnancy assessment
Thyroid function tests – rule out contributing factors

✅ Fasting Required?
