Sperm selection before intracytoplasmic sperm injection

Current Trends in Clinical Embriology, 2015
In assisted reproduction techniques (ART), the success of embryo development depends mostly on the quality of gametes, and pregnancy outcome is strictly related to both the oocyte and the fertilizing sperm quality.

Sperm selection for intracytoplasmic sperm injection

JBRA Assisted Reproduction, 2010
The application of assisted reproduction techniques has provided help to many men seeking to father a child, although the current success of these procedures remains suboptimal.

Sperm Separation and Selection Techniques to Mitigate Sperm DNA Damage

Life
Semen preparation and sperm selection techniques exploit the morphological and physiological characteristics of sperm function, including motility, morphology, density, and maturity, as reflected by their cell-surface charge and the expression of ...

Density‐dependent patterns of multivariate selection on sperm motility and morphology in a broadcast spawning mussel

Ecology and Evolution, 2022
Sperm cells exhibit extraordinary phenotypic variation, both among taxa and within individual species, yet our understanding of the adaptive value of sperm trait variation across multiple contexts is incomplete.

#159 : Aneuploidy Embryos Rate in Good Prognosis Patients After Fertilization Using ICSI and IMSI Methods

Fertility & Reproduction, 2023
Background and Aims: Embryo aneuploidy is caused by many factors, including patient age, sperm quality and sperm selection method. There are several methods for selecting sperm, ICSI (intracytoplasmic sperm injection) and IMSI (intracytoplasmic ...

No evidence for pre-copulatory sexual selection on sperm length in a passerine bird. [PDF]

PLoS ONE, 2012
There is growing evidence that post-copulatory sexual selection, mediated by sperm competition, influences the evolution of sperm phenotypes. Evidence for pre-copulatory sexual selection effects on sperm traits, on the other hand, is rather scarce.

Sperm quality metrics were improved by a biomimetic microfluidic selection platform compared to swim-up methods

Microsystems & Nanoengineering, 2023
Sperm selection is an essential component of all assisted reproductive treatments (ARTs) and is by far the most neglected step in the ART workflow in regard to technological innovation.

The birth of a healthy child in a married couple with a history of multiple unsuccessful attempts at ART by selecting sperm on oocyte-cumulus complexes. Case report [PDF]

Гинекология, 2023
In male infertility, couples must use assisted reproductive technologies with the intracytoplasmic sperm injection (ICSI) technique. A significant disadvantage of ICSI is bypassing natural selection barriers since selective processes in the female ...

Sexual selection in a transparent worm : insights from fluorescent sperm [PDF]

, 2015
Sexual selection is a potent source of selection underlying the evolution of sexual dimorphism, reproductive strategies and mating systems. Although sexual selection was initially thought to occur exclusively at the pre-copulatory stage (e.g., contests ...
