Ovulatory dysfunction can be severe enough to prevent conception (anovulation), or only a contributing factor (oligo-ovulation).
“A number of methods can be used to determine if and when ovulation occurs. Directly or indirectly, all are based on one or another of the hormonal events that characterize the normal ovulatory cycle. Each of the available tests is useful and no one test is necessarily best.
- Menstrual History
- Basal Body Temperature
- Serum Progesterone Concentration – Luteal-phase progesterone drawn about 1 week before the expected menses. A progesterone concentration level less than 3 ng/mL implies anovulation.
- Urinary LH Excretion.
- Endometrial Biopsy and luteal phase deficiency
- Transvaginal ultrasonography.
