title: Sperm morphology after hen's egg yolk filtration.
abstract: Tyrode's washed spermatozoa were placed on top of 20 per cent hen's egg yolk column of 2 cm diameter and 10 cm in height. The spermatozoa were allowed to move downward for two and a half hours and those at the bottom of the column were removed for morphological examination under a light microscope after staining with hematoxylineosin. The study was made in 45 cases. It was found that the percentage of morphologically abnormal sperm decreased, after passing through the hen's egg yolk column, from the average of 9.98 to 0.71 per cent. It is suggested tha the hen's egg yolk method is suitable for improving sperm motility and morphology in certain infertile cases where husbands have a seminal defect.
