The dynamics of uptake of testosterone-1alpha,2alpha-3H(n) by different tissues of the reproductive system in the rabbit embryos from the 18th till 25th days of development was studied in vitro experiments. The specific uptake of the hormone was recorded at all stages under study and in all organ rudiments. The selective uptake was observed in males in the genital tubercle from the 20th till the 25th day, in the ducts on the 19--21st and 25th days, in the urogenital sinus (the cyclic one) on the 19th, 21st, 23rd and 25th days. The character of the hormone selective uptake in the organs-targets is similar in the embryos of both sexes and corresponds to the male morphogenesis. The females were, however, characterized by the higher uptake of the hormone in the ducts on the 19--21st days and in the urogenital sinus on the 19--23rd days. The hormone uptake in the gonads is similar in embryos of both the sexes. The problem of reception of the organs-targets rudiments during the period of growth and differentiation of the embryonic genital system is discussed.
通过体外实验研究了从发育第18天到第25天的兔胚胎生殖系统不同组织对睾酮-1α,2α-3H(n)的摄取动态。在研究的所有阶段和所有器官原基中均记录到了该激素的特异性摄取。在雄性中，从第20天到第25天在生殖结节、第19 - 21天和第25天在导管、第19天、第21天、第23天和第25天在泌尿生殖窦（周期性的）中观察到选择性摄取。两性胚胎中激素在靶器官的选择性摄取特征相似，且与雄性形态发生相对应。然而，雌性的特征是在第19 - 21天的导管和第19 - 23天的泌尿生殖窦中对激素的摄取较高。两性胚胎性腺中的激素摄取相似。讨论了胚胎生殖系统生长和分化期间靶器官原基的接受问题。
