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.

Signaling Enzymes Required for Sperm Maturation and Fertilization in Mammals
Frontiers in Cell and Developmental Biology, 2019 In mammals, motility and fertilizing ability of spermatozoa develop during their passage through the epididymis. After ejaculation, sperm undergo capacitation and hyperactivation in the female reproductive tract – a motility transition that is required ...

Effect of electroacupuncture on total motile sperm count and sperm motility
Journal of Public Health ResearchBackground: Approximately 50% of infertility cases are attributed to male factors. Acupuncture has long been employed as a complementary therapy to enhance male infertility treatment outcomes. This study aimed to assess the impact of electroacupuncture (EA) therapy on sperm motility and TMSC in male infertility patients.

Oocyte–cumulus cell interaction: a key factor in early embryo development
Biological Reviews, EarlyView.ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.

Di (2-ethylhexyl) phthalate reduces sperm motility by decreasing sperm tail energy supply
Ecotoxicology and Environmental SafetyDi (2-ethylhexyl) phthalate (DEHP) is widespread in the environment. It can impair sperm function through damaging the sperm development process. However, few studies have focused on the sperm tail that is directly related to sperm motility.

The costs of extra‐pair behaviours in birds
Biological Reviews, EarlyView.ABSTRACT Extra‐pair behaviours – reproductive behaviours, including those related to copulation and paternity of offspring, amongst animals outside of a social pair bond – have long intrigued behavioural ecologists, particularly from the female animal's perspective.
