Ovulation Induction
Ovulation Induction
It is a treatment in which medications are given to triggers the ovum. If any woman is not ovulating by herself then ovulation induction may be required. The common causes of failure to ovulate are stress, weight fluctuations and Polycystic Ovarian Syndrome (PCOS). Rest causes may include disorders of the pituitary gland, thyroid gland, and raised prolactin levels. In some cases, the failure of ovulation is due to ovarian failure. This might occur following treatment for cancer or maybe the start of the menopause – premature ovarian failure. Ultrasound scans (follicle tracking) and hormone assessments may help to identify the fertile time of the month and so improve the chances of natural conception.
Before ovulation problems can be treated it is important to undertake certain tests to establish the cause. These tests include an ultrasound scan of the ovaries and womb and blood tests to measure a range of hormones including thyroid, prolactin, FSH, LH, Testosterone and other androgens (male hormones). It is also important to ensure that the ovary is capable of responding to drug treatment.
