. Fertility, pre‐freeze and post‐thaw sperm motility, penetration ability and duration of motility in cervical mucus of spermatozoa were studied in 7 heterologous insemination donors and in 4 men in connection with homologous inseminations. No conception occurred after 50 heterologous and 15 homologous inseminations using semen preserved at—196°C. The post‐thaw motility, penetration ability and duration of motility in cervical mucus of spermatozoa were reduced by the freeze‐preservation procedure. The fertilizing capacity of freeze‐pre‐served semen was more reduced than expected from the post‐thaw sperm motility and penetration ability. The semen quality was of significant importance for the post‐thaw sperm motility and penetration ability.
