Hello! Thanks for writing to us. Irregular periods and infertility are due to PCOS,a condition best managed by improving your lifestyle. Improvements in diet and exercise will decrease the severity of annoying PCOS symptoms and will improve your fertility and help regulate your menstrual cycle.You can help to manage your PCOS by eating healthy and exercising to keep your weight at a healthy level. This helps to lower blood glucose (sugar) levels, improve the body s use of insulin, and normalize hormone levels in your body. Even a 10 percent loss in body weight can restore a normal period and make your cycle more regular.Metformin has also been found to help with PCOS symptoms. Lack of ovulation is usually the reason for fertility problems in women with PCOS. Medications that stimulate ovulation can help women with PCOS become pregnant. Treatment options for fertility include: Clomiphene citrate, Metformin with clomiphene , Gonadotropins, In vitro fertilization (IVF). Gonodotrophins are more expensive and raise the risk of multiple births compared to clomiphene. Laparoscopic ovarian drilling is a surgical treatment that can trigger ovulation in women with polycystic ovary syndrome (PCOS).Electrocautery or a laser is used to destroy parts of the ovaries. This surgery is not commonly used. But it can be an option for women who are still not ovulating after losing weight and trying fertility medicines. You can consult with Gynacologist and endocrinologist for treatment. Hope this could help you.
