  Human chorionic gonadotropin that is widely used for improving spermatogenesis. The effect of chorionic gonadotropin is mediated through luteinizing hormone receptor. Treatment with gonadotropin is associated with undesirable effects due to hyperactivation of testosterone production and luteinizing hormone receptor desensitization. A promising alternative could be low-molecular-weight agonists of luteinizing hormone receptors, but their effects on spermatogenesis have not been investigated. Here we analyzed the effect of a thieno[2,
