title: Sperm morphology: unstained and stained smears in fertile and infertile men.
abstract: Two semen specimens from 34 fertile donors and 82 male partners of infertile couples were evaluated for semen quality. Sperm morphology was evaluated with unstained specimens and following Papanicolaou staining. A significant difference (p less than 0.001) was found in the percentage of morphologically normal spermatozoa in stained and unstained semen smears. Fertile semen donors had a significantly (p less than 0.001) higher percentage of normal sperm than men of unproven fertility. When compared to the fertile donors, 78% of the infertile men had increased teratospermia. Papanicolaou staining appears to enhance sperm morphology and allow improved discrimination of sperm head abnormalities.
