Post natal development of albino rat testis: Histological and immunohistochemical study

Abstract

Infertility is a major human health problem which can begin at any age. Approximately 15 % of couples are infertile, and among these couples, male factor infertility accounts for approximately 50 percent of causes. Testicular growth is important for future male fertility which shows acceleration during puberty. This study was carried out to evaluate the histological and morphometric changes that occur in albino rat testis during pre-pubertal, pubertal and post pubertal periods. This would be of help in understanding the testicular behavior and their correlations to infertility problems. Fifty male albino rats were used and subdivided into three groups:- Group (I) :- (pre pubertal group) This group was classified into two subgroups:- Subgroup IA: - included 10 rats of two weeks age. Subgroup IB: - included 10 rats of one month age. Group (II) :- (pubertal group) This group consisted of 10 rats of two months
