RESUMO

<p><b>OBJECTIVE</b>To investigate the effect of the secretory proteins of the ventral prostate on the glycoproteins in the oviductal fluid of golden hamsters.</p><p><b>METHODS</b>Male golden hamsters were divided into four groups: sham operation (SH), total removal of accessory sex glands (TX), and retainment of the ventral prostate only (VP). Oviductal fluid was collected from female hamsters at 0.5, 2, 4 and 6 h after mating with the males of different operated groups with or without ventral prostate. Glycoproteins were probed with a panel of lectins and their changes in the oviductal fluid were analyzed by Western blot.</p><p><b>RESULTS</b>The 47 000, 52 000, 81 000 and 128 000 WGA-binding proteins were observed in the oviductal fluid of the 6 h TX group, the 32 000, 35 500, 47 000 and 52 000 WGA-binding glycoproteins noted in the 6 h VP group, the 47 000, 68 000, 95 000 and 128 000 pisum sativum agglutinin (PSA)-binding glycoproteins shown in the 6 h TX and VP groups, two extra 32 000 and 37 500 bands detected in the 6 h VP group, the 47 000 and 52 000 dolichos biflorus agglutinin (DBA)-binding glycoproteins present in the 6 h VP but absent in the 6 h TX group.</p><p><b>CONCLUSION</b>Ventral prostate secretory proteins affect acetylglucosamine, N-acetylgalactosamine/galactose and mannose in the oviductal fluid collected 6 hours after mating. And these glycoproteins may play an important role in the development of embryos.</p>
