The correct option is C Fructose
Testis has sertoli cells and leydig cells which produce various hormones. Leydig cells produces androgens which include testosterone and androstenedione. These are further converted to estrodial and estrone by an enzyme – aromatase. Sertoli cells produce androgen binding protein and inhibin. Fructose is secreted by seminal vesicles which also secrete prostaglandins and ascorbic acid. Prostate does not secrete prostaglandins as was originally thought. Prostate chiefly secretes acid phosphatase and citrates.
