Previous operations on the internal genitalia reduced the chances of conceiving essentially more than a history of one episode of pelvic inflammation, whereas several episodes of pelvic inflammation seemed to spell an equally unfavorable prognosis. As expected, infertility caused by oral contraceptive\u2010conditioned oligo\u2010amenorrhea was considerably easier to treat than other forms of infertility. Oligo\u2010amenorrhea was significantly more common among patients who had used oral contraception for 1\u20136 years than among those who had used it for less than 1 year.\u2014The incidence of abortion in patients with secondary infertility was about three times higher before than after the infertility investigations.<\/jats:p><jats:p>Lastly, the individual infertility diagnoses were analyzed in the same way, as regards relative share and importance. About 42 per cent of the operated patients succeeded in conceiving.
