Hi, my wife has pcos, had an ovarian drilling this January, unfortunately they just did 2 punctures in ovaries, her periods didn t correct by itself in fact it became worst now..is it advisable to do another ovarian drilling again this yearm with more punctures? We had 6 iui failures before drilling , post drilling we had 1 iui which failed and 1 Ivf resulted in chemical pregnancyp. We are trying to conceive for abt 3 years now with no luck. Our obgyn said we might lose eggs if we do another ivf after proper drilling, but also she said there is an increased chance in iui.. Lwe d are confused now..even before she had drilling she ovoluted with letrozole and few times with clomid...
