In Vitro Fertilization [PDF]

open access: yes, 2021
The field of In Vitro Fertilization is a relatively new field in medicine, constantly on the move. This field is an exquisite example of the vast power in the complementary use of basic research with clinical practice and opened a new route of great ...

In Vitro Fertilization [PDF]

open access: yesJournal of Biological & Scientific Opinion, 2013
The history of in vitro fertilization (IVF) in humans, and in particular its origins as a way of understanding the genetic basis of human disease, is described. Then the range of current genetically related applications of the technique is described, including studies on the genetics of early development and infertility, preimplantation genetic ...

Involvement of sperm acetylated histones and the nuclear isoform of Glutathione peroxidase 4 in fertilization [PDF]

open access: yes, 2017
We previously demonstrated that the nuclear form of Glutathione peroxidase 4 (nGPx4) has a peculiar distribution in sperm head, being localized to nuclear matrix and acrosome and that sperm lacking nGPx4 are more prone to decondensation in vitro. In this

Toward in vitro fertilization in Brachiaria spp. [PDF]

open access: yes, 2010
Brachiaria are forage grasses widely cultivated in tropical areas. In vitro pollination was applied to accessions of Brachiaria spp. by placing pollen of non-dehiscent anthers on a solid medium near isolated ovaries.

Critical Steps of Plasmodium falciparum Ookinete Maturation [PDF]

open access: yes, 2020
The egress and fertilization of Plasmodium gametes and development of a motile ookinete are the first crucial steps that mediate the successful transmission of the malaria parasites from humans to the Anopheles vector. However, limited information exists

Influence of sperm-oocyte coincubation period on porcine in vitro fertilization (IVF) efficiency [PDF]

open access: yes, 2010
A major obstacle for successful in vitro production of porcine embryos is the polyspermic fertilization. One possibility to reduce polyspermic penetration is decreasing the number of spermatozoa added to the fertilization medium. Unfortunately, the lower

Breast Cancer Risk After Ovarian Stimulation for In Vitro Fertilization [PDF]

open access: yes, 2016
The study by Dr van den Belt-Dusebout and colleagues1 investigated a debated aspect of reproductive medicine: breast cancer risk following ovarian stimulation for in vitro fertilization (IVF).2-5 The authors concluded that “these findings are consistent

Post-copulatory opportunities for sperm competition and cryptic female choice provide no offspring fitness benefits in externally fertilizing salmon [PDF]

open access: yes, 2016
There is increasing evidence that females can somehow improve their offspring fitness by mating with multiple males, but we understand little about the exact stage(s) at which such benefits are gained.

Cryptic choice of conspecific sperm controlled by the impact of ovarian fluid on sperm swimming behavior [PDF]

open access: yes, 2013
Despite evidence that variation in male–female reproductive compatibility exists in many fertilization systems, identifying mechanisms of cryptic female choice at the gamete level has been a challenge. Here, under risks of genetic incompatibility through

Porcine oocyte maturation in vitro : role of cAMP and oocyte-secreted factors: a practical approach [PDF]

open access: yes, 2016
Polyspermy or the penetration of more than one sperm cell remains a problem during porcine in vitro fertilization (IVF). After in vitro culture of porcine zygotes, only a low percentage of blastocysts develop and their quality is inferior to that of in ...
