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.

The effect of leukaemia inhibitory factor (LIF) on bovine embryo development in vitro : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Animal Science at Massey University [PDF]
The aim of the study was to investigate the effect of Leukaemia Inhibitory Factor (LIF) either during in vitro maturation (IVM) or in vitro culture (IVC) on bovine embryo development. Three main experiments were conducted using oocytes aspirated from 2-8

Analysis of the mechanism by which calcium negatively regulates the tyrosine phosphorylation cascade associated with sperm capacitation [PDF]
The capacitation of mammalian spermatozoa involves the activation of a cAMP-mediated signal transduction pathway that drives tyrosine phosphorylation via mechanisms that are unique to this cell type.

A cost for high levels of sperm competition in rodents: Increased sperm DNA fragmentation [PDF]
Spermcompetition, a prevalent evolutionary process inwhich the spermatozoa of two or more males compete for the fertilization of the same ovum, leads to morphological and physiological adaptations, including increases in energetic metabolism that may ...

Ca2+ ionophore A23187 can make mouse spermatozoa capable of fertilizing in vitro without activation of cAMP-dependent phosphorylation pathways [PDF]
Ca2+ ionophore A23187 is known to induce the acrosome reaction of mammalian spermatozoa, but it also quickly immobilizes them. Although mouse spermatozoa were immobilized by this ionophore, they initiated vigorous motility (hyperactivation) soon after ...

Partial Deletion of Chromosome 8 β-defensin Cluster Confers Sperm Dysfunction and Infertility in Male Mice [PDF]
β-defensin peptides are a family of antimicrobial peptides present at mucosal surfaces, with the main site of expression under normal conditions in the male reproductive tract.

Compartmentalization of distinct cAMP signaling pathways in mammalian sperm. [PDF]
Fertilization competence is acquired in the female tract in a process known as capacitation. Capacitation is needed for the activation of motility (e.g. hyperactivation) and to prepare the sperm for an exocytotic process known as acrosome reaction. While

Potassium ion influx and Na+,K+-ATPase activity are required for the hamster sperm acrosome reaction. [PDF]
The role of a K+ ion influx and Na+,K+-ATPase activity in the hamster sperm acrosome reaction (AR) was examined, using a range of concentrations of K+,K+ ionophores and a Na+,K+-ATPase inhibitor.

A Fluorometric Method for Measurement of Sperm Capacitation
SummaryA fluorometric technique for measurement of sperm capacitation is described. Rabbit sperm were labeled with tetracycline HCI (T-HCI) and placed in uteri and oviducts of estrous and pseudopregnant does and in other regions of estrous females.
