Abstract

Beta-carotene and vitamin A were estimated in 125 specimens of human seminal fluid and spermatozoa. In 72 of the specimens triiodothyronine, tetraiodothyronine, and T4-binding globulin were also determined. Vitamin A in seminal fluid increased from 10.4+/-l.8 microgram (SE) in severe oligozoospermia up to 19.1+/-2.5 microgram/100ml in specimens with high sperm densities. In spermatozoa, however, there was a trend for a decrease in vitamin content from 2.1+/-0.8 to 0.2 +/-0.07 microgram/108. In the majority of cases beta-carotene was undetectable and, when present, the levels were much lower than those of vitamin A. The amounts of triiodothyronine and tetraiodothyronine in seminal fluid were 0.19+/-0.03 ng/ml and 1.1+/-0.18 microgram/100ml, respectively. No correlation was found between levels of both hormones and quality of seminal fluid. T4-binding globulin was either very low or undetectable.
