Abstract: | Summary Different steps in mouse ovarian and testicular development have been studied in order to compare the time sequences during the in vivo differentiation of steroidogenic cell populations growing in contact with male and female gonocytes. These time sequences indicated a basic common developmental pattern: early signs of steroid synthesis in the male gonad, but late entering into meiotic prophase of XY germ cells; early meiosis but late steroidogenic activity in the ovary. In both male and female interstitial tissues, signs of involution were found following a period of exponential development.Dedicated to Prof. Dr. med. H.
