摘要: Insulin-like factor 3 (INSL3) affects testicular descent. Mutations in the INSL3 gene or its receptor, LGR8/GREAT, can cause cryptorchidism. Expression of LGR8/GREAT different tissues and production by adult-type Leydig cells suggest additional roles for this hormonal system adults. We used a novel radioimmunoassay kit to measure concentrations serum normal men those with pathologies. demonstrate that circulates adult is almost exclusively origin. Subjects severe damage (infertility) produce small amounts INSL3, hormone seem reflect functional status cells. Analysis treated combinations hormones hypothalamus-pituitary-testis axis suggests related luteinizing hormone.
