Roles of the oviduct in mammalian fertilization [PDF]
REPRODUCTION, 2012 The oviduct or Fallopian tube is the anatomical region where every new life begins in mammalian species. After a long journey, the spermatozoa meet the oocyte in the specific site of the oviduct named ampulla and fertilization takes place. The successful fertilization depends on several biological processes that occur in the oviduct some hours before ...

Understanding early reproductive failure in turtles and tortoises
Animal Conservation, EarlyView.Turtles and tortoises are facing a global extinction crisis, and hatching failure is an increasing problem. In this paper, we synthesize the current literature on fertilization and hatching success in turtles and tortoises, test innovative tools for monitoring fertility and embryo survival rates and describe how these approaches can be adopted by ...

Loss of maternal annexin A5 increases the likelihood of placental platelet thrombosis and foetal loss [PDF]
, 2012 Antiphospholipid syndrome is associated with an increased risk of thrombosis and pregnancy loss. Annexin A5 (Anxa5) is a candidate autoantigen. It is not known, however, whether endogenous Anxa5 prevents foetal loss during normal pregnancy.

Bovine embryo-oviduct interaction in vitro reveals an early cross talk mediated by BMP signaling.
Reproduction, 2017 Signaling components of bone morphogenetic proteins (BMPs) are expressed in an anatomically and temporally regulated fashion in bovine oviduct. However, a local response of this signaling to the presence of the embryo has yet to be elucidated. The aim of

Bisphenol A induces superfeminization in the Ramshorn snail Marisa cornuarietis (Gastropoda: Prosobranchia) at environmentally relevant concentrations [PDF]
, 2007 Previous investigations have shown that bisphenol A (BPA) induces a superfeminization syndrome in the freshwater snail Marisa cornuarietis at concentrations as low as 1 μg/L.

Deep learning classification method for boar sperm morphology analysis
Andrology, EarlyView.Abstract Background Boar semen quality emphasizes three major criteria: sperm concentration, motility, and morphology. Methods to analyze concentration and motility quickly and objectively readily exist, but few exist for analyzing morphology outside of subjective manual counting.

IMMACULATE CONCEPTION, INCUBATION PROTOCOLS, AND EGG CHARACTERISTICS OF THE GANGES SOFTSHELL TURTLE (ASPIDERETES GANGETICUS) [PDF]
, 2006 Reproductive biology of Aspideretes gangeticus was studied between 1986 and 2001. Clutchsize averaged 17.9 eggs and ranged between six to thirty-fi ve eggs. Egg length averaged 30.6 mm,egg width averaged 30.22 mm, and egg weight averaged 16.85 g.

Andrology, EarlyView.Abstract Background Ascorbic acid 2‐glucoside (AA2G) is a stabilized form of ascorbic acid and a potent antioxidant. Ascorbic acid is present in the testes and epididymis and helps maintain the physiological integrity of reproductive organs. Its properties have been utilized to protect spermatozoa of different species from oxidative stress.
