Název v původním jazyce

Role of sperm surface proteins in reproduction

Popis výsledku v původním jazyce

Seminal plasma is a mixture of secretory products of the male reproductive organs. Boar seminal plasma proteins (AQN, AWN and PSP spermadhesins, DQH sperm surface protein, proteinase inhibitors) are multifunctional proteins with the ability to bind various endogenous ligands in the male and female reproductive tracts. Spermadhesins are secreted mainly by the seminal vesicles (SV), but their mRNAs have been found also in the cauda epididymis and prostate. The mRNA transcript of DQH protein was found onlyin SV. Spermadhesins and the DQH protein bind to the sperm surface at ejaculation and they participate in the formation of the sperm oviductal reservoir and sperm-ZP primary binding. Acrosin inhibitor mRNA was detectable in epididymis, SV, prostate. Byindirect IMF, acrosin inhibitors were detected in the secretory tissues of cauda epididymis, prostate and SV, and on epididymal and ejaculated spermatozoa.
