Effect of sperm storage and selection techniques on sperm parameters
Systems Biology in Reproductive Medicine, 2014Sperm cryopreservation preserves the fertility of cancer patients undergoing chemotherapy, ensures sperm are available at the time of oocyte retrieval in assisted reproductive technology (ART) procedures and avoids the need for repeated sperm extraction surgeries in azoospermic patients.

Sperm Preparation Techniques and Advanced Sperm Selection for Intracytoplasmic Sperm Injection
2023Despite years of research, numerous questions persist regarding the most effective sperm selection techniques. Frequently, new methods have gained popularity without thorough, extensive trials demonstrating their benefits. It is evident that there is no universally applicable solution, and it remains uncertain whether any of those techniques are ...

With advances in assisted reproduction techniques, the degree of demand on the male gamete has decreased to such a level that the role of the sperm has been reduced to a mere packet of DNA to be released into the cytoplasm of the oocyte. Now, we know that regardless of appearance, this package may contain unpleasant surprises such as sperm DNA damage ...

Sperm Processing and Selection
2020Assisted reproductive technology (ART) use sperm sorting methods to select viable sperm from semen samples. Conventional sperm sorting techniques currently use swim-up and density gradient centrifugation. These methods use multiple centrifugation steps, which have been shown to generate reactive oxygen species (ROS) that decrease DNA integrity and ...

Sperm Processing and Selection
2012The application of assisted reproductive techniques (ART) has provided help to many men seeking to father a child, although the current success rates of these procedures remain suboptimal. Since raw semen cannot be used in most ART, a workup of the ejaculate is needed to extract those sperm that are capable to fertilize the egg.

Artificial Insemination with Husband'S Sperm (Aih): Techniques for Sperm Selection
Archives of Andrology, 1989Artificial insemination with husband's sperm (AIH) attempts to treat infertile couples by solving their particular infertility problems. This review is concerned with detailing and evaluating the experiences of different authors with AIH in infertile couples, types of insemination, and indications for insemination, with emphasis on techniques for sperm

Microfluidics for Sperm Selection
2014Traditional methods for sperm selection such as swim-up and isopycnic (density gradient) centrifugation involve prolonged periods of incubation and/or serial centrifugations. Prolonged incubation of sperm with other cellular components of semen and serial centrifugation expose motile sperm to reactive oxygen species.

Sex selection by sperm separation and insemination
Fertility and Sterility, 1984The Ericsson albumin filtration technique was used to collect a fraction rich in Y sperm for selective insemination in couples desiring a male infant. Of 35 conceptions in which sex was known at delivery or spontaneous abortion, there were 28 males (80%).

Sperm Selection Capacity of Cervical Mucus
Archives of Andrology, 1984Seventeen couples who attended the Infertility Clinic for routine fertility investigations were used in the study. Complete morphological examinations were performed on the ejaculates and cervical mucus samples following coitus in order to determine the morphological selective capacity of the mucus.

On the selective elimination of Y-bearing sperm
Immunogenetics, 1978The potential use of antibodies that selectively recognize either X-bearing or Y-bearing sperm is self-evident. Thus our attention was directed to the fact that under optimal conditions, H-Y antibody lyses 50% of mouse spermatozoa. Accordingly, we asked whether expression of H-Y antigen is haploid in spermatozoa from XY male mice heterozygous for the ...
