Abstract
Human oocytes in different stages of maturation were obtained by follicular aspiration from women given Clomovid and Gonadex. Particles similar to type-C virus were observed in 3 out of 16 oocytes. The particles were irregularily distributed along the oocyte membrane. They were seen both in a state of budding and as free lying in the perivitelline space. Reverse transcriptase activity was detected in 3 out of 9 samples of follicular fluid obtained from women other than those yielding the oocytes. It is assumed that these findings indicate the expression of endogeneous retroviruses in human oocytes.This publication has 10 references indexed in Scilit:
