| Hormone | What It Does | Ideal Timing | What High/Low May Mean |
| AMH (Anti-Müllerian Hormone) | Estimates your egg reserve | Anytime | 🔽 Low = fewer eggs remaining (low ovarian reserve)🔼 High = possible PCOS or high egg reserve |
| FSH (Follicle-Stimulating Hormone) | Helps grow follicles (eggs) | Day 2–4 of cycle | 🔼 High = low ovarian reserve🔽 Low = may signal hormone imbalance |
| LH (Luteinizing Hormone) | Triggers ovulation | Day 2–4 & mid-cycle | 🔼 High on day 3 = possible PCOSMid-cycle surge = ovulation likely |
| Estradiol (E2) | Estrogen that supports egg growth | Day 2–4 | 🔼 High = may mask high FSH or signal low egg quality🔽 Low = may indicate poor ovarian response |
| Progesterone | Confirms ovulation occurred | | |
