Cryptorchidism is associated with male infertility in adulthood, primarily due to poor semen quality, which can be linked to compromised Sertoli cell function and its impact on Leydig cell function.[4]Cryptorchidism, hypospadias, testicular cancer, and poor semen quality collectively constitute testicular...

for normal testicular descent are not well understood, which therefore makes it difficult to understand the reason why undescended testes occur in some males. There is some genetic component, as one study has concluded that 6% of fathers of males with undescended testes also had the condition....
Laboratory Studies For unilateral undescended testis without hypospadias, no laboratory studies are needed. Bilateral nonpalpable testes associated with either hypospadias or ambiguous genitalia may represent a life-threatening situation. Consultation with a pediatric endocrinologist and/or geneticist is recomme...
Often the undescended testis can be brought down into the scrotum by medical treatment with the gonadotropic hormone, and for physical and psychologic reasons this method is preferred. Frequently, however, surgery (called orchiopexy) is required. This operation is not particularly serious and is ...
Several studies have indicated that cryptorchidism is associated with degenerative changes in both Sertoli cells and germ cells. The gonadal peptide hormone inhibin B reflects Sertoli cell function. Low inhibin B levels are found in a large portion of formerly cryptorchid men who show compromised semi...
Cryptorchidism (undescended testes) is one of the most common congenital abnormalities observed in boys, and is one of the few known risk factors for testicular cancer The key factors associated with the occurrence of cryptorchidism remain elusive Few factors are supported by consistent evidence of ...
