Intrauterine
IUI can be used in conjunction with controlled ovarian hyperstimulation (COH). Clomiphene Citrate is the first line, Letrozole is second line, in order to stimulate ovaries before moving on to IVF. Still, advanced maternal age causes decreased success rates; women aged 38–39 years appear to have reasonable success during the first two cycles of ovarian hyperstimulation and IUI. However, for women aged over 40 years, there appears to be no benefit after a single cycle of COH/IUI. Medical experts therefore recommend considering in vitro fertilization after one failed COH/IUI cycle for women aged over 40 years.
