Ovulation disorders; infrequent or absent ovulation ( anovulation), typically results in infrequent periods ( oligomenorrhea).
These results are:
1) Fewer opportunities to conceive
2) Difficulty in detecting a woman’s fertile period
3) Eggs not “breaking” through the follicle wall
4) Eggs being released out of sync with other factors crucial to fertilization and implantation.
Causes of ovulation disorders include hypothalamus dysfunction, hyper-prolactinemia, PCOS, luteal phase defects, tumors of the pituitary and adrenal glands or ovaries.
Less typical causes are:
1) Primary ovarian failure
2) Resistant ovary syndrome
3) Auto-immune oophoritis.
A battery of tests need to be done to work out the problem and there after treatment can be planned.
