Hello, Thank you for your question. Infertility is defined as the inability of a couple to become pregnant after one year of unprotected intercourse in women under 35 years of age and after six months in women 35 or older. The ability of a couple to become pregnant depends on normal fertility in both the male and female partners. Because pregnancy requires normal fertility in both the male and female , health care providers routinely involve both partners in the evaluation. A women can have trouble getting pregnant for different reasons. Include: problem with ovulation. Ovulation is a time in a woman s monthly cycle when the ovary releases an egg into the fallopian tube. Women have the highest chance of getting pregnant if they have sex 1 to 2 days before ovulation or on the day of ovulation. It is 14 days before your last menstruation period. Problem with the uterus or fallopian tubes- for example, some women have scar tissue in their fallopian tube from past infection or surgery. Endometriosis- is a condition that can cause pain in the lower part of the belly. Your doctor will talk with you an do an exam. He or she will do often do tests to try to figure out the cause of the problem. Plus, your partner might need to be tested too. But dont be surprised if your doctor can not tell you what is wrong. It s not always possible to find out why a woman cannot get pregnant. For you have a problem with ovulation.The method of ovulation induction selected should be based upon the underlying cause of anovulation(no ovulation) and the efficacy, costs, risks, and potential complications associated with each method as they apply to the individual women. Option include: Weight modulation( keep your BMI in standard level), Clomiphene citrate, Metforming or other indulin-sensitizing agents, Gonadotropin therapy, Aromatase inhibitors, Laparoscopic ovarian diathermy, assisted reproductive technology.. For your problem your doctor choose to use Metformin(benforce-m). Insulin resistance in commonly observed in women with PCOS. Correction of hyperinsulinemia with metformin has a beneficial effect in anovulatory women with PCOS because this leads to an increase in menstrual cyclicity and enhanced spontaneous ovulation. However, live birth rates are not as high as those achieved with clomiphene. A consensus group has recommended against the routine use of metformin for ovulation induction except in women with glucose intolerance. However, the addition, metformnin may provide additional metabolic effects that are beneficial for pregnancy. If you are overweight, losing weight might help you become pregnant. Hope I have answered your query. Let me know if I can assist you further. Best regards, Dr. Heang Chan Raksmey, General and Family Physician.
