What are Ovulatory disorders?
Anovulation or lack of ovulation is a condition in which follicular development and rupture is impaired. This leads to infertility as oocyte(egg) is not released from its follicle. This Ovarian dysfunction can be due to genetic disorders or hormone deficiency. Common causes of ovulatory disorders are PCOS, premature menopause, excess prolactin or low gonadotropic hormones. Excess loss of weight, extreme exercise, use of certain drugs and stressful environment can also lead to anovulation. Ovulation detection tests are direct tests such as ultrasound or laparoscopic visualisation of follicular rupture, and indirect tests such as progesterone dosage, basal temperature curve and endometrial biopsy. Ovulation can be predicted by serum estradiol and LH concentrations and evaluation of the cervical mucus. Ovulation induction can overcome this situation in many cases.
