<s>[INST] Hi doctor, My wife has periods issue. She was on birth control pills for about 3 years to get periods. We got married six months ago. She stopped them now as we pretty soon started thinking of having a baby. My doubts are will sex trigger periods? Is there any connection between these? Is there any other way to induce period? She is 32 now and so we are little concerned. She also has a phobia of intercourse. When we address the issue with a therapist, I would like to know medically anything can be done to make her get periods. Once she is comfortable with intercourse then we will go down that path. Please suggest. [/INST] Hi. First, we should consider the reason behind the fact that she needs pills to get periods. Was she diagnosed with any hormonal problem? If not then she has to do blood/serum tests. Hb % (hemoglobin), TC (total blood count), DC (differential count), fasting blood sugar, TSH (thyroid stimulating hormone), prolactin, testosterone, FSH (follicle stimulating hormone), LH (luteinizing hormone) and ultrasound of pelvis, to know the exact cause, depending on which medicines can induce periods. Sex can trigger periods only if there is any psychological issue. But do not rely on this. Yes, medically a lot can be done to induce periods and ovulation. </s>
