Unexplained Infertility
Prognosis for Unexplained Infertility
The pregnancy rate is the same (about 65%) whether in vitro fertilization is used immediately after unsuccessful treatment withclomipheneplus hCG or whether gonadotropins with intrauterine insemination are used next before trying in vitro fertilization. plus hCG is unsuccessful, more clinicians now recommend in vitro fertilization as the next treatment. Data indicate that women > 38 with unexplained infertility conceive more quickly and costs are lower when in vitro fertilization is done before controlled ovarian stimulation is tried ( Prognosis reference ). 1.Goldman MB, Thornton KL, Ryley D, et al: A randomized clinical trial to determine optimal infertility treatment in older couples: The forty and over treatment trial (FORT-T).Fertil Steril101(6):1574–1581, 2014.
