In vitro spermatogenesis: A century‐long research journey, still half way around
Reproductive Medicine and Biology, 2018 Background Spermatogenesis is one of the most complicated cellular differentiation processes in a body. Researchers struggled to find and develop a micro‐environmental condition that can support the process in vitro.

Plasma and testicular testosterone levels, volume density and number of Leydig cells and spermatogenic efficiency of rabbits [PDF]
, 2002 Plasma and tissue testosterone concentrations were determined by radioimmunoassay in 12 eight-month-old sexually mature New Zealand White rabbits and evaluated for possible associations with spermatogenic efficiency as well as with volume density and ...

Modern competency‐based teaching of human sexual development
Anatomical Sciences Education, EarlyView.Abstract Embryology is an integral part of anatomy and a key subject in basic medical education. The development of the sexual tract, which is closely associated with the formation of the urinary tract and the organs of continence, is particularly complex and relevant for many medical disciplines.

Paternal use of metformin and risk of major congenital malformations: A meta‐analysis of 4 studies
British Journal of Clinical Pharmacology, EarlyView.Abstract Metformin is the first‐line drug for the treatment of Type 2 diabetes. In 2022, a Danish registry‐based study reported a 40% increased risk of major congenital malformations following paternal exposure during spermatogenesis. This raised widespread concern about the use of metformin in males of reproductive age.
