Read the following statements related to testis and find out the incorrect statements.
a. Each testicular lobule contains one to three highly coiled seminiferous tubules in which sperms are produced.
b. Each seminiferous tubule is lined on its inner side by two types of cells called Leydig cells and Sertoli cells.
c. The region outside the seminiferous tubules called interstitial space, contain small blood vessels and male germ cells (spermatogonia) which lead to sperm formation.
d. In testis immunologically competent cells are also present.
e. The seminiferous tubules of the testis open into the rete testis through vasa efferentia.

The correct option is D b, c and e
Seminiferous tubule
Each seminiferous tubule is lined on its inside by two types of cells called male germ cells (spermatogonia) and Sertoli cells.
Sertoli cells are supporting cells. The spermatogonia grow into primary spermatocytes, which undergoes meiosis to produce the spermatids.
The regions outside the seminiferous tubules called interstitial spaces contain small blood vessels and interstitial cells or Leydig cells. Leydig cells synthesize and secrete testicular hormones called androgens (testosterone).
The seminiferous tubules of the testis open into the vasa efferentia, through rete testis.
Final answer
d. b, c and e.
