    Author: Vijaykumar B, Ramjaneyulu T, Sharanabasappa A, Patil SB.
    Journal: J Environ Biol; 2002 Jan; 23(1):43-6. PubMed ID: 12617315.
    Abstract:
    Histological and biochemical studies carried out on the male reproductive organs of the Indian garden lizard, Calotes versicolor after the treatment with pituitary gonadotrophins (FSH and LH), showed a significant increase in the weight, protein content and diameter of testis, but decrease in its cholesterol. The spermatogonia, spermatocytes and spermatids increased significantly in the germinal epithelium of seminiferous tubule, and spermatozoa appeared in its lumen. The Leydig and Sertoli cells were hypertrophied with increase in their nuclear diameter. The epidymal weight, diameter and protein content also increased after gonadotrophins treatment. There was a significant decrease in the testicular cholesterol indicating the utilization of cholesterol for steroid hormone synthesis. The combined gonadotrophin (FSH + LH) treatment was more effective than the individual gonadotrophin treatment.
