Abstract
An experiment was conducted to observe histomorphometric and cellular toxicity on rat testes after sixty days of methotrexate administration intraperitoneally (ip). Total 30 adult male rats were divided into one control and two experimental groups containing 10 rats in each group. Experimental groups received methotrexate in two different doses i.e 25 ig and 50 ig, whereas control one received normal saline intraperitoneally. At the end of the experiment, animals were sacrificed and testes were processed for paraffin sectioning and stained in haematoxylin and eosin. Further microscopic study of seminiferous tubules, interstitial spaces, primary spermatocytes and spermatids were carriedout. Results revealed decreased diameter of seminiferous tubules, increased interstiial spaces in experimental groups in dose dependent manner and found to be statistically significant (p < 0.05) as well as distortion of morphology of Leydig cells in experimental group. Therefore, it can be concluded that these qualitative and quantitative changes in male gonads may alter the reproductive performance of animals.
