| Abstract: | During 1-20 days of pregnancy rats were given 20% alcohol orally in a dose 0.4 mg/kg bw. This led to a significant increase in the nuclear volume of germ cells in male 19-day embryos. A karyological analysis of 2-month offspring germ cell generations at stage VII of seminiferous epithelium cycle revealed a reliable decrease in the number of spermatids on step 7 of development after introduction of antenatal alcohol. The increased proportion of spermatocytes with meiotic chromosomes pathological behaviour due to alcohol was determined by the proposed quantitative analysis of meiotic divisions. |
