Abstract The 49-day non-return rate (67.9 percent) to first inseminations obtained with posterior uterine deposition of 2.0 or 2.5 million sperm in 0.5 ml Caprogen with catalase was significantly higher than that achieved after deep cervical deposition (63.1 percent) or deep uterine penetration before posterior uterine deposition (65.3 percent). Comparable results were obtained with second inseminations.
