    • Androgen receptor gene CAG and GGN repeat polymorphisms in Chilean men with primary severe spermatogenic failure 
      Castro-Nallar, Eduardo; Bacallao, Ketty; Parada-Bustamante, Alexis; Lardone, María C.; López, Patricia V.; Madariaga, Marcia; Valdevenito, Raúl; Piottante, Antonio; Ebensperger, Mauricio; Castro, Andrea (2010)
      There is ample documentation supporting the fact that androgens are required for normal spermatogenesis. A minority of infertile men have abnormal testosterone blood levels or mild androgen receptor mutations. We investigated ...
