Sperm progressive motility has been reported to be one of the key factors influencing in vitro fertilization rates. However, recent studies have shown that sperm DNA fragmentation is a more robust predictor of assisted reproductive outcomes including reduced fertilization rates, embryo quality, and pregnancy rates. This study aimed to compare the usefulness of sperm progressive motility and DNA...

Science and technology have introduced new concepts and options to the whole world, including the Muslim world. Some momentous effects of technology include the linkages of previously isolated groups and communities, extension and qualitative change of life and health, and the potential for imminent and horrible human-inflicted death.

METHODS We recruited the participants from th...

About 10-15% of couples have difficulty conceiving at some point in their reproductive lives and thus have to seek specialist fertility care. One of the most commonly used treatment options is in vitro fertilization (IVF) and its related expansions. Despite many recent technological advances, the average IVF live birth rate per single initiated cycle is still only 30%. Consequently, there is a ...

The ambiguous status of unborn human life contributes to the interminability of the debate about the morality of abortion. New medical research and therapies are implying questions about the value and protectability of life in its earliest stages, to which in vitro fertilization now gives more access. This essay will address especially the interplay of scientific information about embryonic dev...

Catholicism is the only major world religion that unequivocally bans the use of in vitro fertilization (IVF). Nevertheless, in Ecuador, Catholic IVF practitioners declare God's dominion over their IVF laboratories and clinics in explaining pregnancy outcomes. My analysis of this routine combination of spiritual and material causal models in Ecuadorian IVF contributes to two ongoing discussions ...

This paper analyses elements of the legal process of consent to the donation of 'spare' embryos to research, including stem-cell research, and makes a recommendation intended to enhance the quality of that process, including on occasion by guarding against the invalidity of such consent. This is important in its own right and also so as to maximise the reproductive treatment options of couples ...

Surrogacy is not regulated by a single legal instrument only, nor is confirmation of a surrogacy agreement by the High Court an unqualified green light for the surrogacy process to proceed. In the context of the HIV status of the commissioning father, whose gametes are to be used for the conception of the child in pursuance of a surrogacy agreement, the intended in vitro fertilisation of the su...

The association between educational level and cycle outcomes was quantified by applying multivariable logistic and linear regression within a prospective cohort of 2,569 women commencing their first in vitro fertilization (IVF) cycle. Although a woman's educational attainment was not associated with the likelihood of implantation failure, chemical pregnancy, spontaneous abortion, or live birth,...

Background: Failed fertilization post ICSI has been mainly attributed to the sperm’s inability to induce oocyte activation. Phospholipase C Zeta (PLCζ) is considered to be a primary factor for the induction of oocyte activation. The aim of this study was to quantitatively assess the expression of PLCζ in globozoospermic or individuals with previous low or failed fertilization in comparison to f...
