The influence of relaxin on motility of human sperm in vitro.
Sperm of healthy men were incubated in an IVF medium with relaxin at concentrations of 3, 30, 300 and 3000 ng ml-1. Immediately after addition of relaxin and 60 and 120 min later motility, progressive motility, mean path velocity, mean progressive velocity, mean linearity and mean lateral head displacement were measured with the Hamilton-Thorn motility analyser. Neither immediately after relaxin addition, nor after 60 or 120 min, was an improvement of sperm motility observed at any concentration.
