Ovarian Drilling
After surgery, ovulation occurs spontaneously in 70-90% of women and the probability of pregnancy after one year is in the region of 40-60%. There is no increased risk of multiple pregnancy or OHSS. If ovulatory cycles fail to restore after the surgery, the doctor may restart ovulation induction. A recent study up to 20 years after laparoscopic drilling has shown persistence of ovulation over many years. Compared with medical treatment, it need only be performed once and intensive monitoring is not required.
The main problems associated with surgery include adhesion formation, the risk of destruction of the ovaries leading to ovarian failure. In addition, there are risks associated with surgery and anaesthesia.
Laparoscopic ovarian
The proportion of women with regular menstrual cycles increases substantially after drilling and is sustained at long-term follow-up. Ovulation and pregnancy rates are substantially increased in the period after the operation and appear to be maintained. Resistance to the effects of ovarian drilling include marked obesity, very elevated levels of androgens, and long duration of infertility. Addition of other ovulating agents such as clomiphene citrate or FSH appears to improve the effectiveness of laparoscopic ovarian drilling
