Evaluation of a non‐radioactive rapid test for determination of serum progesterone in South American camelids

Veterinary Record, EarlyView.
Abstract Background Determination of the serum progesterone (P4) concentration is of high importance in reproductive medicine and may be applied for diagnosing pregnancy in South American camelids. P4 measurements in alpacas and llamas are usually performed using immunoassays, which are time consuming and require appropriate expertise of laboratory ...

Testicular histopathology and its association with germ cell numbers, serum concentrations of reproductive hormones, and semen quality

Andrology, EarlyView.
Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.

Low testosterone levels in men at age 31 associates with future risk of prediabetes and type 2 diabetes: A birth cohort study

Andrology, EarlyView.
Abstract Objective We aimed to investigate the association of a low serum testosterone concentration with the risk of abnormal glucose metabolism (i.e., prediabetes and type 2 diabetes) in men at a 15‐year follow‐up. Study population and methods In a population birth cohort, men with low testosterone (testosterone < 12.1 nmol/L, n = 136) and normal ...
