Boys whose testes have not descended at birth -- a condition known as cryptorchidism -- are almost three times as likely to develop testicular cancer in later life, finds a new analysis. Boys whose ...

The loss of anatomical features is a frequent evolutionary event. For example, humans and other great apes have lost their tails and whales have lost their legs. The most convincing evidence comes ...

Complete descent of a testis occurs in two distinct stages. Both involve a ligament attached to the base of the testis, the gubernaculum (from the same Ancient Greek stem that gave us “governor”). In ...

The results suggested that early prolonged hormonal therapy is advisable in all patients with cryptorchidism to increase the speed of testicular descent to the scrotum achieved by surgery, and thereby ...

Puberty is full of ups and downs — sometimes literally. The moment when testicles descend is a pivotal one in the male life cycle, but as scientists point out in a PLOS Biology study published ...

Androgens control rodent inguinoscrotal testicular descent during a “programming window” (E12–17). It is proposed that androgen masculinises the genitofemoral nerve, but the mechanism remains unknown.

The loss of anatomical features is a frequent evolutionary event. For example, humans and other great apes have lost their tail and whales have lost their legs. The most convincing evidence comes from ...

The efficacy of LHRH in cryptorchidism is still debated. The aim of this study was to quantify testicular descent after LHRH therapy. Synthetic LHRH (Hoe 471) was given intranasally in a spray dose of ...

Boys whose testes have not descended at birth—a condition known as cryptorchidism—are almost three times as likely to develop testicular cancer in later life, finds an analysis of the available ...

The fossil record preserves predominantly vestiges of hard structures such as bones or teeth. Consequently, resolving the evolution of soft-tissue structures such as muscle or brain tissue requires ...
