A variety of evolutionary processes has led to the development of different organs to ensure
that internal fertilization occur successfully. Fallopian tubes are a particularly interesting …

Following insemination of spermatozoa pre-ovulation, the mammalian oviduct ensures, by
the formation of a functional sperm reservoir (SR), that suitable (low) numbers of viable and …

Polyspermy is an important anomaly of fertilization in placental mammals, causing
premature death of the embryo. It is especially frequent under in vitro conditions …

In recent years, progress has been achieved in the production of pig embryos through IVM
and IVF techniques. Cytoplasmic maturation of oocytes has been improved by modifications …

In the pig, a functional tubal sperm reservoir (SR) is established before ovulation to ensure
availability of suitable numbers of viable spermatozoa for fertilization. The boar's large …

BACKGROUND Heparan sulphates play key roles in conception and early pregnancy
events. The role of heparin, a structural analogue, and its application to assisted conception …

Our ability to screen the structural and functional integrity of the spermatozoon in vitro has
increased markedly over the past decades, but our capacity to estimate the fertility of a …

High polyspermy is one of the major limitations of porcine invitro fertilisation (IVF). The
addition of oviductal fluid (OF) during IVF reduces polyspermy without decreasing the …

A block to polyspermy is required for successful fertilisation and embryo survival in
mammals. A higher incidence of polyspermy is observed during in vitro fertilisation (IVF) …

A reliable, easy to assess marker for fertility in agricultural species would be highly desirable
and Anti-Müllerian Hormone (AMH) is a promising candidate. This review summarizes …
