In one stallion and patients with impaired spermatogenesis, only repressors were found.It is concluded that (i). stallion and man reveal a different CREM expression pattern, (ii). the expression of CREM activators is a prerequisite for normal spermatogenesis, and (iii). the lack of CREM activator expression results in male infertility.
