Improving ARTs: Microfluidics as a Tool for Sperm Selection

Andrology, EarlyView.
ABSTRACT Sperm selection is a critical step in assisted reproductive technology (ART), as sperm quality directly influences embryo quality. In vivo, the female reproductive tract imposes several physical and physiological barriers that favors only the most optimal spermatozoa reaching the fertilization site.

Sperm Selection Using Micro Swim‐Up: Improvement of Chromatin Integrity Compared to Density Gradient Centrifugation

Andrology, EarlyView.
ABSTRACT Background Selecting high‐quality spermatozoa with optimal nuclear integrity is a crucial step in assisted reproductive technologies (ART). While density gradient centrifugation (DGC) is widely used, the associated centrifugation steps may induce cell stress, potentially damaging sperm DNA.

Hemodynamic parameters and reproductive outcome after intracytoplasmic sperm injection and fresh embryo transfer in patients undergoing oocyte retrieval with general anesthesia using fentanyl, remifentanil or alfentanil – A randomized clinical trial

Taiwanese Journal of Obstetrics & Gynecology, 2019
Objective: Anesthesia for assisted reproductive technology is very important to provide less stressful and painful environment for patients, with minimal side effects on oocytes. In the present study, we aimed to evaluate hemodynamic parameters, recovery

Live Birth Rates After Varicocele Embolization in Patients After Failed In Vitro Fertilization With Intracytoplasmic Sperm Injection

Andrology, EarlyView.
ABSTRACT Background and Objectives While in vitro fertilization with intracytoplasmic sperm injection (IVF‐ICSI) bypasses abnormalities in sperm concentration, motility, and morphology, it still has a significant failure rate. We report our experience on the effect of varicocele embolization (VE) on couples with varicocele related primary male factor ...

Children Born Using Ejaculated Sperm From Men With Klinefelter Syndrome. Is Sperm Production Associated With Testicular Volume?

Andrology, EarlyView.
ABSTRACT Background A large number of children have been born using testicular sperm from men with Klinefelter syndrome (KS), whereas reports of children conceived using ejaculated sperm are rare. Objective To review all published cases of children conceived using ejaculated sperm from men with KS, assess their health and karyotype, and evaluate ...

Biallelic Truncating Variant in LRGUK Is Associated With Severe Multiple Morphological Abnormalities of the Sperm Flagella and Sperm Nuclear Defects in Humans

Clinical Genetics, EarlyView.
A homozygous truncating variant in LRGUK results in loss of the LRGUK protein and causes multiple morphological abnormalities of the flagella (MMAF), disrupted axonemal architecture, central pair defects, abnormal chromatin organization, and severe male infertility, establishing LRGUK as a novel human infertility gene.

Changes in Testosterone Levels Following Surgical Sperm Retrieval in Men with Non-Obstructive Azoospermia: Systematic Review and Meta-Analysis

The World Journal of Men's Health
Purpose: Surgical sperm retrieval (SSR) is used to extract spermatozoa for use with intracytoplasmic sperm injection in men with obstructive and non-obstructive azoospermia (NOA).

Preimplantation Genetic Testing for Families at Risk of Haemophilia: Ten‐Year Single‐Centre Experience

Haemophilia, EarlyView.
ABSTRACT Introduction Preimplantation genetic testing for monogenic diseases (PGT‐M) is a reproductive option for couples at high risk of transmitting inherited disorders. We report a ten‐year single‐centre PGT‐M experience in families at risk of hemophilia.

Artificial intelligence model for the assessment of unstained live sperm morphology

Reproduction and Fertility
Traditional sperm morphology assessment requires staining and high magnification (100×), rendering sperm unsuitable for further use. We aimed to determine whether an in-house artificial intelligence (AI) model could reliably assess normal sperm ...
