Advances in male contraception

The methods devised for male contraception are meager. The authors review t he various nonhormonal methods applied for contraception including vas defe rens interference and heat. The former comprises the no-scalpel vasectomy, percutaneous vasal injection, the "Shug" method, and the argon laser vasal photocoagulation. Heat methods used wet heat, and artificial cryptorchidism was created by testicular suspension. The testicle was suspended in the su perficial inguinal pouch close to the scrotal neck using 2 methods: stitch and ball. Two recently developed methods for male contraception-polyester-i nduced azoospermia and prolactin injection-are described. The azoospermic e ffect of the polyester sling seems to be due to (1) creation of an electros tatic field across the intrascrotal structures, and (2) disordered thermore gulation. Prolactin administration as a contraceptive method is efficient a nd safe and has the potential to be developed as a male contraceptive. The methods, especially testicular suspension and polyester suspensors, are sim ple and easily applicable and were well accepted by the subjects.
