• Unexplained Infertility
  • A woman's maximum monthly chance of becoming pregnant after unprotected intercourse is about 30%.
  •  Infertility is diagnosed after 1 year of unsuccessful attempts to become pregnant. 
  • A basic infertility evaluation consists of assessing ovarian function, semen parameters, and tubal status. 
  • If no problems are found, a diagnosis of unexplained infertility is made. In such cases, the likelihood of becoming pregnant during subsequent months is, at best, only a few percent.
  • Further attempts to achieve pregnancy can be successful, however, so expectant management still has a role.
  •  Alternatively, various forms of assisted reproductive technology can be offered. 
  • Timed intercourse, ovarian stimulation—with or without intrauterine insemination (IUI) or even in vitro fertilization (IVF)—can be considered.
