Abstract

Polyzoospermia has been repeatedly associated with reduced fertility and increased rates of spontaneous abortion. We examined semen samples of 1374 infertile men and found an incidence of 4.2% of semen with a sperm density exceeding 250 X 10(6) sperm cells/ml. The spontaneous pregnancy rate in 30 evaluated couples in whom the male partner presented with polyzoospermia was 38.7% and the spontaneous abortion rate was 25%. Sperm penetration tests revealed normal mucus-penetrating ability in 29 of 30 men examined. The reason for reduced reproductive performance in polyzoospermic men does not seem to be disturbed sperm mucus interaction.

Psychologic stress in the workplace and spontaneous abortion.

The relation of work-related psychologic stress to spontaneous abortion was examined in a prospective study of 3,953 pregnant, employed members of a prepaid health plan in California, recruited between 1990 and 1991. Information on occupation, psychologic stress-related factors at work, social support at work, physical exertion at work, life events, pregnancy worries, and potential confounders was obtained by a telephone interview. Psychologic job stress and social support at work were assessed using an abbreviated version of the instrument developed by Karasek and colleagues (Los Angeles: University of Southern California, 1986). Results from the multivariate model indicated that, overall, stressful work was not associated with an increased risk of spontaneous abortion. However, interactions were observed between stressful work and maternal age over 32 years (p = 0.04), cigarette smoking (p = 0.02), and primigravidity (p = 0.06). Relative to the odds ratio for stressful work in young, nonsmoking, multigravid women without a history of two or more spontaneous abortions, the odds ratios for spontaneous abortion given stressful work were higher by 2.45 (95% confidence interval (CI) 1.03-5.81) for older women, 2.96 (95% CI 1.16-7.52) for smokers, and 2.27 (95% CI 0.97-5.27) for primigravid women.
