One-hundred-and-twenty couples with male factor, cervical factor, unexplained or immunological infertility underwent direct intraperitoneal insemination (DIPI) of capacitated spermatozoa, combined with ovarian stimulation for a total of 254 cycles. Pregnancy occurred in 47 cycles, resulting in an overall pregnancy rate of 40.5% per patient (two pregnancies occurred in two patients) and a cycle fecundity of 18.5%.

However, there were two pregnancies where the inseminates had a count of 0.1 x 10(6) total motile spermatozoa. DIPI as an outpatient, in-vivo conception procedure offers encouraging results and is recommended before attempting more costly and invasive assisted reproduction techniques.

Abstract

One-hundred-and-twenty couples with male factor, cervical factor, unexplained or immunological infertility underwent direct intraperitoneal insemination (DIPI) of capacitated spermatozoa, combined with ovarian stimulation for a total of 254 cycles. Pregnancy occurred in 47 cycles, resulting in an overall pregnancy rate of 40.5% per patient (two pregnancies occurred in two patients) and a cycle fecundity of 18.5%. Of the patients, 23 have delivered live infants (one twins, 22 singletons), 15 (32%) miscarried and 9 have ongoing pregnancies. The cycle fecundity rates increased with increasing sperm concentration and total progressive motile count, both before and after sperm preparation (r = 0.8161, r = 0.8717 and r = 0.759, r = 0.795, respectively). However, there were two pregnancies where the inseminates had a count of 0.1 x 10(6) total motile spermatozoa. DIPI as an outpatient, in-vivo conception procedure offers encouraging results and is recommended before attempting more costly and invasive assisted reproduction techniques.
