What is a luteal phase defect pregnancy?
This is an ovulation disorder where an egg is released but the corpus luteum (the yellow structure left in the ovary after ovulation) does not produce enough progesterone. As a result, the lining of the uterus does not thicken properly and a fertilized egg is unable to embed. The luteal phase (the time from ovulation to the next period or post-ovulation phase, 37) is often shorter than it should be.
Sometimes treatment may be given in the form of clomiphene: this is an ovulation stimulation drug, which in effect boosts ovulation and thereby increases the progesterone level, maintaining the thicker lining of the uterus to give enough time for the fertilized egg to implant. If this is not effective, then assisted conception such as IVF may be used.
