In vitro production (IVP) of embryos and associated technologies in cattle have shown
significant progress in recent years, in part driven by a better understanding of the full …

BACKGROUND It has long been thought that the factors affecting embryo and foetal
development were exclusively maternally derived; hence, if issues regarding fertility and …

In vitro fertilization (IVF) gives rise to embryos in a number of mammalian species and is
currently widely used for assisted reproduction in humans and for genetic purposes in cattle …

Sperm migration through the female genital tract is not a quiet journey. Uterine contractions
quickly operate a drastic selection, leading to a very restrictive number of sperm reaching …

Bisphenol A (BPA), a plasticizer and endocrine disruptor, has been substituted by bisphenol
S (BPS), a structural analogue that had already shown adverse effects on granulosa cell …

In mammalian females, after sperm are deposited in the reproductive tract, a fraction of
sperm migrates to the lower oviduct (isthmus) and forms a sperm storage site known as the …

Semen modifies the expression of genes related to immune function along the porcine
female internal genital tract. Whether other pathways are induced by the deposition of …

The sperm storage tubules located in the mucosal folds of the uterovaginal junction (UVJ)
are the primary site of sperm storage in chicken hens after natural mating or artificial …

The contribution of sperm to embryogenesis is gaining attention with up to 50% of infertility
cases being attributed to a paternal factor. The traditional methods used in assisted …

The sperm reservoir is formed after insemination in mammals, allowing sperm storage in the
oviduct until their release. We previously showed that physiological concentrations of …
