Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Assembly of the Inner Perivitelline Layer, a Homo log of the Mammalian Zona Pellucida: An Immunohistochemical and Ultrastructural Study [PDF]

, 2012
The avian inner perivitelline layer (IPVL), a homologous structure to the mammalian zona pellucida, is deposited between the granulosa cells and the oocyte cell membrane during folliculogenesis. The glycoprotein meshwork of the IPVL forms a 3-dimensional

Protective Effect of Intracellular Compounds of Lactobacillus plantarum on Goat Sperm Quality During Cryopreservation

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Intracellular compounds from Lactobacillus plantarum were added to a goat sperm cryopreservation extender. A concentration of 20 µL/mL improved post‐thaw sperm quality, whereas higher concentrations (80–100 µL/mL) had detrimental effects. ABSTRACT Background Cryopreservation of sperm is a key strategy for preserving and transmitting the genetic traits ...

Bicarbonate is required for migration of sperm epididymal protein DE/CRISP-1 to the equatorial segment and expression of rat sperm fusion ability [PDF]

, 2004
Numerous studies have demonstrated that sperm capacitation is a bicarbonate-dependent process. In the rat, capacitation has not been studied as much as in other species, mainly because of the difficulties in carrying out functional assays with this ...

Innate Immunity and Microbial Recognition in Reproduction: From Barrier Defense to Maternal–Fetal Tolerance

The FASEB Journal, Volume 40, Issue 8, 30 April 2026.
Graphical abstract illustrating the barrier defense–tolerance framework of reproductive innate immunity. Across the female and male reproductive tracts and the maternal–fetal interface, epithelial barriers, innate sensors, immune cells, and microbial signals are integrated to preserve reproductive homeostasis.

Analysis of CAPZA3 localization reveals temporally discrete events during the acrosome reaction [PDF]

, 2010
In mammals, the starting point of development is the fusion between sperm and egg. It is well established that sperm fuse with the egg through the equatorial/post-acrosomal region.

Development of an analytical method to determine malondialdehyde as an oxidative marker in cryopreserved bovine semen [PDF]

, 2015
Frozen sperm is widely used in artificial insemination of cattle as well as other animal species. As a consequence of the freezing and thawing processes of semen, an excess of reactive oxygen species (ROS) are formed.
