Primary infertility: correlation between sperm migration test and humoral immunity

Area of Science:

• Reproductive Immunology
• Infertility Research
• Sperm Function Testing

Background:

• Unexplained primary infertility affects numerous couples.
• The poor sperm migration test (P.S.M.T.) is a diagnostic tool used in infertility evaluations.
• The role of circulating immune factors in infertility requires further investigation.

Purpose of the Study:

• To assess the significance of circulating immune factors in couples with unexplained infertility and a poor sperm migration test.
• To evaluate the predictive value of immune factor testing in this specific patient group.

Main Methods:

• A modified Kibrick test was employed to detect circulating immune factors.
• Sera from 11 couples with unexplained infertility and P.S.M.T. were analyzed.
• Control sera included WHO samples, known positives, prevasectomy samples, and sera from infertile couples with organic pathology.

Main Results:

• A positive immune factor titer was found in 2 female and 3 male subjects among the 11 couples studied.
• Control groups showed low positive titers (1/49 prevasectomy, 4/17 with organic pathology).
• Two wives of male subjects with positive titers conceived spontaneously.

Conclusions:

• The presence of circulating immune factors in couples with unexplained infertility and P.S.M.T. was observed.
• The findings question the predictive value of the poor sperm migration test in assessing fertility potential.
• Further research is needed to clarify the role of immune factors in unexplained infertility.
