Benchmarks defining high‐quality sperm in the common marmoset (Callithrix jacchus)
Andrology, EarlyView.Abstract Background Common marmosets (Callithrix jacchus) are increasingly recognized as valuable nonhuman primates (NHPs) for biomedical research due to their small size and short reproductive cycle and lifespan relative to other NHP species. Maximizing the utility of captive research marmosets, including genetically manipulated animals, will require ...

Oviductal and uterine leiomyomata in mares [PDF]
, 2013 This paper describes a case of a sessile uterine leiomyoma in a 17-year-old chronic infertile Selle Francais mare. The mass was removed by transendoscopic electrocoagulation.

Circadian regulation of reproduction: From gamete to offspring [PDF]
, 2013 P01326625; Grants: GNT0519315Few challenges are more critical to the survival of a species than reproduction. To ensure reproductive success, myriad aspects of physiology and behaviour need to be tightly orchestrated within the animal, as well as timed ...

Inhibition of ROS1 activity with lorlatinib reversibly suppresses fertility in male mice
Andrology, EarlyView.Abstract Background Inhibition of sperm maturation in the epididymis is a promising post‐testicular strategy for short‐acting male contraceptives. It has been shown that ROS1, a receptor tyrosine kinase expressed in the epididymis, is essential for epididymal differentiation, sperm maturation, and male fertility in mice.

Behavior of ACRBP-deficient mouse sperm in the female reproductive tract
The Journal of Reproduction and Development, 2018 Gene-knockout mice lacking ACRBP, a proacrosin-binding protein localized in the acrosome of sperm, have been shown to exhibit male subfertility, owing to abnormal formation of the acrosome.

An air-liquid interphase approach for modeling the early embryo-maternal contact zone [PDF]
, 2017 We developed an air-liquid interphase culture procedure for mammalian oviduct epithelial cells leading to the formation of functional epithelial tissues, which generate oviduct fluid surrogates.

PLoS ONE, 2017 The oviductal microenvironment is a site for key events that involve gamete maturation, fertilization and early embryo development. Secretions into the oviductal lumen by either the lining epithelium or by transudation of plasma constituents are known to

Human asthenozoospermia: Update on genetic causes, patient management, and clinical strategies
Andrology, EarlyView.Abstract Background In mammals, sperm fertilization potential relies on efficient progression within the female genital tract to reach and fertilize the oocyte. This fundamental property is supported by the flagellum, an evolutionarily conserved organelle, which contains dynein motor proteins that provide the mechanical force for sperm propulsion and ...

Annexin A2 and S100A10 in the mammalian oviduct
Cell and Tissue Research, 2016 In many mammals, upon entry into the female reproductive tract, a subpopulation of sperm is stored in the oviduct forming a functional reservoir. In the oviducts of pig and cow, Annexin A2 (AnxA2) has been linked to the binding of sperm. This protein may
