An androgen-binding protein has been demonstrated in the seminal plasma of the ram (Jegou, 1976), but nothing is known about the existence of such a protein in the seminal plasma of other mammalian species. In the present study, samples of seminal plasma from men, stallions, boars, goats, bulls and rams were examined for 5α-dihydrotestosterone (5α-DHT)-binding activity using polyacrylamide gel electrophoresis. Ejaculates were collected from animals in artificial vaginae and from men by masturbation. Spermatozoa were removed by centrifugation at 1500 g for 15 min at 4 °C and the seminal plasma was stored at − 20 °C until used. After extraction of endogenous steroids by charcoal treatment (10 mg/ml seminal plasma for 30 min at 4 °C), all samples were incubated
Journal of Endocrinology is committed to supporting researchers in demonstrating the impact of their articles published in the journal.
The two types of article metrics we measure are (i) more traditional full-text views and pdf downloads, and (ii) Altmetric data, which shows the wider impact of articles in a range of non-traditional sources, such as social media.
