Surface epithelium in males and females ? | * In females, SE proliferates.... * In males, it regresses and tunica albugenia quickly forms |
Surface epithelium in females turns in to ? | * Cortical cords increase in size and incorporate germ cells.... * Cords break up into clusters with oogonium surrounded by follicular cells (from surface epithelium)= primordial follicle |
Forms the female genital ducts ? | * paramesonephric ducts by fusing caudally |
