[Infertility in ethnic groups. Etiology and treatment]

In this retrospective case control study we analysed the causes and treatments of infertility in 100 ethnic couples consecutively discharged from the Fertility Clinic in the period October 1995 to March 1999. The mean age at referral was 28 years (19-37) for ethnic women and 31 years (24-39) for Danish women. Male infertility was the most frequent cause in ethnic couples compared to Danish couples (24% vs. 16%; NS). Tubal infertility was less frequent in ethnic than in Danish couples (19% vs. 45%; p < 0.01), ovulatory defects were more frequent in ethnic couples than in Danish (13% vs. 4%; p < 0.04). Among ethnic couples 57 (118 cycles) underwent IVF and ICSI treatment vs. 85 (198 cycles) Danish couples (p < 0.01). The ongoing pregnancy rate per initiated cycle was 29.6% in ethnic couples vs. 24.2% in Danish couples (NS). Forty four percent of the ethnic couples did not complete the whole treatment program vs. 29% of Danish couples (p < 0.04). This may be due to cultural differences and difficult communication.
