The most common way for women to get pregnant is natural conception. You can choose to have intercourse during ovulation after three months of pregnancy preparation to increase your chances of conception. Ovulation is about 14 days before the next menstrual period for women with regular menstruation. If menstruation is irregular, ovulation can be determined by ovulation test strips or pelvic ultrasound monitoring. Infertility can be diagnosed if there is no contraception and no pregnancy within a year, mostly due to ovulation disorders, tubal causes and male semen problems. The primary cause should be treated actively. If, after active treatment, natural conception is still difficult, conception can be achieved through assisted reproductive technology. Assisted reproductive technology is now well developed, with mature technology and many methods, including artificial insemination, in vitro fertilization and embryo transfer, gamete transfer, intrafallopian transfer of congeners or embryos, egg donation, microinjection fertilization techniques, etc., which can help women achieve the goal of conception.
