The resazurin test (REZ TEST) was performed on semen samples obtained from 75 untreated subfertile and 10 pregnancy confirmed fertile males. The results were compared with other sperm parameters to assess the quality of semen. The highest correlation of REZ grade was with motile sperm (r = 0.90, P < 0.001), sperm viability (r = 0.80, P < 0.001) and sperm(More)
Association between androgens and erythropoiesis has been known for more than seven decades. Androgens stimulate hematopoietic system by various mechanisms. These include stimulation of erythropoietin release, increasing bone marrow activity and iron incorporation into the red cells. Before the discovery of recombinant erythropoietin (rhEpo), androgens were(More)
The presence of immunosuppressive early pregnancy factor (EPF) in the maternal serum has so far been associated with gestation. Its presence in the serum of women with gestational trophoblastic tumors was investigated. The results indicate that while EPF activity was detected in the serum of women with choriocarcinoma, no such activity was detected in the(More)
PROBLEM A discrepancy exists between the apparently normal ovulation and the pregnancy rates in women treated with clomiphene citrate (CC). Our previous studies have indicated that immuno-suppressive "early pregnancy factor" (EPF) is a novel marker to detect subclinical embryonic loss in infertile women. METHOD In the present study EPF was used as a(More)
The isolation and partial characterization of an immunosuppressive early pregnancy factor (EPF) present in the serum of pregnant women, between 3 and 8 weeks of gestation, is described. EPF was purified using ion-exchange chromatography, affinity chromatography and HPLC gel permeation techniques. A homogeneous, active fraction containing a single(More)
The presence of Fc receptors, but not C3 receptors, on human and bovine spermatozoa was shown by sperm-induced rosette formation of antibody-treated ox erythrocytes and by immunofluorescence of aggregated human gammaglobulin (AHG) treated spermatozoa. Human and bovine spermatozoa bound AHG as well as circulating immune complexes (CIC) from human sera;(More)
Semen characteristics were studied in 96 men from an in-vitro fertilization and embryo transfer programme. Along with the routine semen analysis, the presence of sperm antibodies in seminal plasma was measured by an ELISA technique. Antibodies to spermatozoa (IgA and/or IgG) were present in 19 cases and 15 of these (78.95%) had abnormally high viscosity,(More)
