KR has been unsuccessfully trying to get pregnant for 1.5 years with irregular periods and no positive ovulation readings. She is feeling depressed and has questions about seeing a fertility specialist. A fertility specialist can run tests on both partners to determine the cause of infertility and has extensive training in this area. The first visits would involve hormone level tests and the second would include additional tests like ultrasounds, hormone tests, and procedures like hysteroscopy and laparoscopy to examine the reproductive organs. If clomiphene treatment fails to induce ovulation, injectable fertility drugs may be considered. Metformin is sometimes used alongside clomiphene to treat infertility in women with PCOS.
