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.
