title: Improved conception rate after intrauterine insemination of washed spermatozoa from men with poor quality semen.
abstract: The efficacy of high intrauterine insemination of a washed motile fraction of spermatozoa from men with poor quality semen on the day after the luteinising hormone (LH) surge was compared with that of natural intercourse based on symptothermal methods and a single act of intercourse timed on the day after the LH surge in the same 35 couples in a controlled and randomised trial of the three types of cycle. Each couple had been trying to conceive for at least 3 years, the woman being potentially fertile and the only detectable defect related to poor semen quality. After 39 intrauterine insemination cycles, 8 women conceived (all in their first insemination cycle); this procedure was significantly more successful than LH-timed intercourse (0/38; p less than 0.05) and natural intercourse timed by symptothermal methods (1/34; p = 0.022). The technique of intrauterine AIH, with a 'Tomcat' catheter, was simple, painless, and uncomplicated.
