​Fertility tests help diagnose the causes of infertility in both men and women. For women, tests may include hormone level assessments (e.g., FSH, LH, estrogen), ovulation tracking, ultrasound to check for ovarian reserve or polycystic ovary syndrome (PCOS), and hysterosalpingography (HSG) to examine fallopian tube health. For men, semen analysis evaluates sperm count, motility, and morphology. Additional tests may include hormone testing and genetic screening. Other diagnostic tools, like laparoscopy, may be used to check for conditions like endometriosis. These tests help identify underlying issues and guide treatment options for those trying to conceive.
