[Idiopathic subfertility: pregnancy rate after IVF treatment in minimally stimulated monofollicular ovarian cycle].

Fifty-nine patients with idiopathic subfertility were treated with IVF in 176 minimally stimulated cycles. Twenty pregnancies were achieved, resulting in pregnancy rates of 11.4% per treatment cycle and 21.3% per embryo transfer. Thus, the mode of treatment described here appears to be an useful alternative to IVF or laparoscopic GIFT in gonadotropin-stimulated cycles, since it carries good chances of success while avoiding the risk of massive ovarian hyperstimulation and increased incidence of multiple pregnancies.
