Formation of antisperm antibodies in women treated with fallopian tube sperm perfusion.
Fallopian tube sperm perfusion (FSP) is a combination of ovarian stimulation and intra-uterine insemination using a large volume (4 ml) of inseminate containing 10(7)-10(8) spermatozoa. The inseminate will flush the Fallopian tubes and some of it will end up in the pouch of Douglas. In the present study, we have investigated whether the FSP method will result in the formation of serum antisperm antibodies in the female. A total of 184 treatment cycles were given to 128 women. The indications for treatment were: unexplained infertility (n = 35), various infertility diagnoses (n = 28) and donor insemination (n = 65). Prior to treatment, 11 (8.6%) women had a positive tray-agglutination test (Friberg) and/or a positive immunobead test. After completing one to four treatment cycles, another six (4.7%) women had developed serum antisperm antibodies. The antibodies induced by the treatment were of isotype IgM and directed against the tail-tip of the spermatozoa. Two of the women, who prior to the treatment had antisperm antibodies, showed an increase in antibody titre during treatment. There was no statistically significant difference in the pregnancy rate between the women with antisperm antibodies and the women without. In our opinion, the small risk of developing antisperm antibodies is no contra-indication for treating infertile couples with FSP.
