I got this question in semester exam.

My question is based upon Drug Distribution in section Distribution of Drugs of Drug Biotechnology

Answer 1

The correct choice is (d) Restricts the passage of drugs to spermatocytes and spermatids

For explanation I would say: Blood-testis barrier is a tight junction between Sertoli cells located at the capillary endothelial level of the testis. It acts as the blood-testes barrier restricting drugs to spermatocytes and spermatids.
