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 …

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 …

The number of children born since the origin of Assisted Reproductive Technologies (ART)
exceeds 5 million. The majority seem healthy, but a higher frequency of defects has been …

In mammals, the oviduct (or the Fallopian tube in humans) can be divided into the
infundibulum (responsible for oocyte pick-up), ampulla (site of fertilization), isthmus (where …

Once in the female reproductive tract, spermatozoa undergo several modifications to acquire
their complete fertilizing ability. Interactions between the oviductal fluid (OF) and gametes …

In mammals, sperm ascension within the female reproductive tract involves a transient
adhesion to the caudal isthmus of the oviduct. Sperm adhesion to this specialized region …

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 …

Mammalian fertilization remains a poorly understood event with the vast majority of studies
done in the mouse model. The purpose of this review is to revise the current knowledge …

Mammalian oocytes are surrounded by an extracellular coat called the zona pellucida (ZP),
which, from an evolutionary point of view, is the most ancient of the coats that envelope …

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) …
