IS it possible to observe oocytes in the adult clam male gonad histological section? The adult clam males were treated for 28 days with high temperature or/and endocrine-disrupting compounds.
Embryologically, It's Very Possible! Oogonia (That Produces Oocytes) & Spermatogia (That Produces Spermatocytes) are Present Together When The Young One is Developing in The Mother. Since the Young is to Be a Male, The Oocytes Should Shrink & Die Off. But Congenital Malformation Can Make Both Cell Lines Grow Simutaneously, Making The Oocytes to Be Present in The Testicles (The Male Gonads). The Reverse Can Also Occur, Where Spermatocytes & Testosterone are Observed in The Female Gonads (Ovaries).
Oocytes are the highest abundance in winter. The mean oocyte size decreased during spring. Modal oocyte sizes decreased during winter and late spring of each year.
