title: A new method of promoting fertility.
abstract: It has been demonstrated that in selected cases of subfertility in men, the first portion of the split ejaculate is superior to the specimen considered as a whole with regard to sperm density, sperm motility, and sperm morphology and also in those cases where there is increased seminal viscosity in the whole ejaculate. The use of a new coital technic, in which the husband practices coital withdrawal after the deposition of the better first portion of the ejaculate during the fertile time of the wife's cycle, has resulted in rapidly achieving pregnancy in many instances where the marriages had been barren for years. A documentation of 33 instances of pregnancy ascribed to this coital technic in the past 4 years, with detailed analyses of whole and split ejaculate semen, is presented.
