[Clinical study on circulating antisperm antibodies in women with recurrent abortion]. 1990

X C Zhang

Couples with a history of recurrent spontaneous abortions (RSA) were analyzed for circulating antisperm antibodies (Ab) with an enzyme-linked immunosorbent assay (ELISA), a Franklin-Dukes (F-D) and a sperm immobilization test(SIT). The three tests were positive in 31.5%, 25.9% and 18.5% for wives and 24.1%, 11.1% and 7.4% for husbands in RSA couples. There was a statistical significance (P less than 0.01) as compared with the control group. The ELISA method was found to be most sensitive, and the positive rate of antisperm antibodies in wives was higher than that in husbands. The Ab titer of RSA group varied within 1:8 approximately 1:512, with 60% above 1:32. The pregnant weeks (P greater than 0.05) did not seem to affect the antisperm Ab titer, nor did the aborting frequency. Our study suggests that antisperm Ab is one of the important causes of RSA in women.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
D004797	Enzyme-Linked Immunosorbent Assay	An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

D000906	Antibodies	Immunoglobulin molecules having a specific amino acid sequence by virtue of which they interact only with the ANTIGEN (or a very similar shape) that induced their synthesis in cells of the lymphoid series (especially PLASMA CELLS).
D013094	Spermatozoa	Mature male germ cells derived from SPERMATIDS. As spermatids move toward the lumen of the SEMINIFEROUS TUBULES, they undergo extensive structural changes including the loss of cytoplasm, condensation of CHROMATIN into the SPERM HEAD, formation of the ACROSOME cap, the SPERM MIDPIECE and the SPERM TAIL that provides motility.
