Fallopian tube sperm perfusion used in a donor insemination programme.
Ninety-six couples were enrolled in a programme of Fallopian tube sperm perfusion (FSP). FSP is a method combining ovarian stimulation, ovulation induction and intra-uterine insemination with a 4 ml volume of sperm suspension. Frozen/thawed donor semen was used in all cycles. A total of 196 treatment cycles were started and of these 172 were completed. Twenty cycles were cancelled because of maturation of too many follicles, a low ovarian response, or formation of ovarian cysts. Five of the women enrolled in the programme did not have any inseminations. Forty-eight pregnancies occurred (27.9% per cycle) among 45 women (49.5%). There were five spontaneous abortions and one ectopic pregnancy. Sixteen pregnancies are on-going (greater than 12 weeks) and 26 women have delivered (including two sets of triplets and one set of twins). The pregnancy rate declined from the first attempt (34.1%) to the fourth attempt (14.3%). The pregnancy rate was significantly higher in women with three to five mature follicles compared to women with two or fewer mature follicles (P less than 0.05). Cycles in which human chorionic gonadotrophin (HCG) was administered on day 11 or later had a higher pregnancy rate than cycles where HCG was administered on day 10 (P less than 0.01). There was no difference in pregnancy rates between insemination with 8-10 x 10(6) motile spermatozoa and insemination with greater than 30 x 10(6) motile spermatozoa. FSP used in a programme of artificial insemination by donor using frozen/thawed donor semen is relatively simple to perform and gives a high pregnancy rate per cycle.
