Vasectomy and its microsurgical reversal. 1978

S J Silber

In our series the overall pregnancy rate after vasovasostomy in an unselected group of early patients was 71%. Recovery of fertility correlated with the return of normal sperm counts and with the quality of vas fluid on the testicular side of obstruction at the time of vasovasostomy. The three most important factors in our group influencing return of fertility after vasovasostomy were a meticulous microscopic technique for reconnection, the duration of time the vas deferens has been obstructed, and the presence or absence of a sperm granuloma at the site of vasectomy. The presence of a sperm granuloma at the site of vasectomy virtually ensured the presence of good quality sperm in the vas fluid at the time of vasovasostomy. If all three of these factors are favorable, vasectomy may be reversible for more patients.

D013094	Spermatozoa	Mature male germ cells derived from SPERMATIDS. As spermatids move toward the lumen of the SEMINIFEROUS TUBULES, they undergo extensive structural changes including the loss of cytoplasm, condensation of CHROMATIN into the SPERM HEAD, formation of the ACROSOME cap, the SPERM MIDPIECE and the SPERM TAIL that provides motility.
