Sperm Agglutination and Aggregation in Spermogram
Types and degrees of sperm agglutination in spermogram. Distinguishing true agglutination from aggregation and its clinical significance in male infertility.
Blood and bone marrow morphology, clinical cases and diagnostic algorithms. Most of the library is in Russian; the English section is growing.
Most of our material is written in Russian — that is the working language of the community. A few pieces exist in English; the rest of the library is one click away and the photographs need no translation.
