Fifty patients with primary infertility were treated by intrauterine insemination of the husband's semen which had been stored. Thirty patients had sperm counts of greater than 20 × 106/ml with 50% motility and twenty patients had oligospermia (<20 × 106/ml).
The technique of storage of semen is reported and the intrauterine method described. The rôle of the buffer solution is discussed in overcoming the complications of intrauterine insemination. A success rate of 70% is reported in the normospermic group and 55% in the oligospermic group over nine cycles of intrauterine insemination of husband's semen.
