BACKGROUND: Recent alarming trends of a substantial rise in the number of cases of infertility with as many as 30-40% being attributed to male-factor associated causes have created a need for further studies and advancements in semen analysis. Despite the focus on semen analysis over the years, assessment of sperm morphology has not been given due importance although it is a simple, standard and baseline diagnostic modality. It can be used to predict the need and outcome of Artificial Reproductive Techniques such as Invitro Fertilization, Gamete Intra Fallopian Tube Transfer and Intra Cytoplasmic Sperm Injection...

AIM AND OBJECTIVE: This paper aims to explore the ways in which neonatal nurses understand the experience of parents who have experienced infertility, conceived a baby via in vitro fertilisation and delivered an extremely premature infant. The chance of a poor long-term outcome for the baby is significant; therefore, parental anguish plays out in the neonatal intensive care. BACKGROUND: Current literature suggests that infertility is a significant issue for ageing women and many couples experience multiple cycles of invitro-fertilisation (IVF) treatment to achieve a pregnancy...

It has been previously demonstrated (IETS 2011) that Panama is applying the biotechnology of in vitro embryo production (IVP) to their bovine reproduction management systems. The present work demonstrates the ability to apply the IVP technology across 2 distant country borders. Herein, we demonstrate that a country (Dominican Republic; DR) that does not have a bovine IVP laboratory can take advantage of fresh bovine IVP embryos for transfer using distant IVP facilities in another country (Panama; ~1500km away)...

Some time ago an article was published in this journal relating the difficulties of legislating for InVitro Fertilization in a Catholic country and the issues and side issues which had to be faced. Since then one has approached closer to having a law which regulates this technology. However several issues continue to challenge the country. The main concern, other than IVF not being a natural method of having children is the status of the embryo. The normative values of the country in fact induces politicians to discuss an 'embryology act' rather than a 'reproductive medicine' act...

Efficient collection, freezing, reliable archiving of sperm, and re-derivation of mutant mice are essential components for large-scale mutagenesis programs in the mouse. Induced mutations (i.e. transgenes, targeted mutations, chemically induced mutations) in mice may cause inherited or temporary sterility, increase abnormal sperm values, or decrease fertility. One purpose of this study was to compare the effect(s) on fresh and frozen-thawed sperm quality, spermatozoa DNA integrity, unassisted in vitro fertility (IVF) rate, in vitro embryo development rate to blastocysts, and live-born offspring rates in non-ENU (control) animals and the F1-generation of N-ethyl-N-nitrosourea (ENU)-treated male mice (765mg/kg C57BL6/J or 600mg/kg 129S1/SvImJ total dose)...

In-vitro maturation of oocytes (IVM) is a new IVF technology developed in order to avoid iatrogenic complications of standard IVF treatments. This technique is particularly useful in patients suffering from polycystic ovary syndrome (PCOS) who are concerned with the risk of ovarian hyperstimulation syndrome. This technique is nowadays routinely practised in many international centres. However, the efficiency of this technique needs to be improved for a better support of maturation conditions to maximize oocyte developmental competence...

The female parthenogenetic haploid embryos can be stored long-term by cryopreservation. Briefly, rabbit haploid parthenotes at the 32-cell stage were produced by electroactivation and in vitro culture. At this embryonic stage, parthenotes were individually cryopreserved by a slow-freezing procedure. After thawing, every embryo was disaggregated and blastomeres used as haploid maternal donors of nuclei. These nuclei were transferred to androgenetic haploid hemizygotes, obtained by female pronuclear removal offertilizedova...
