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 …

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 …

In the present study, the prevalence of chromatin instability in the fertilizing-competent sperm
population in the porcine oviduct in vivo was examined through qualitative analysis of the …

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 …

Recalling the evolutionary sequence of development first of gonad and subsequently of
oviducts, ovarian endocrine regulation of all known components of oviduct physiology is …

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 …

Spermatozoa interact with their immediate environment and this contact remodels the sperm
surface in preparation for fertilisation. These fundamental membrane changes will be …

The in vitro production of porcine embryos has presented numerous challenges to
researchers over the past four decades. Some of the problems encountered were specific to …

The oviduct (known as the fallopian tube in humans) is the site for fertilization and pre-
implantation embryo development. Female steroid hormones, estrogen and progesterone …

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 …
