The KIF6‐RBP Complex Orchestrates mRNA Transport Required for Sperm Flagellar Assembly

Advanced Science, EarlyView.
Two homozygous deleterious KIF6 variants are identified in unrelated men with impaired sperm motility. Mouse models and multi‐omics analyses reveal that KIF6 cooperates with the RNA‐binding proteins FMRP and FXR1 to deliver mRNAs essential for sperm flagellar assembly, linking disrupted mRNA transport to reduced abundance of key structural and ...

Micro-TESE Outcomes for Non-Obstructive Azoospermia — The First Australian Series

Fertility & Reproduction, 2022
Background: Micro-dissection testicular sperm extraction (micro-TESE) for non-obstructive azoospermia (NOA) was shown to achieve the best sperm retrieval rate (SRR) compared to other techniques.

Sperm cryopreservation protocol for micro-TESE-retrieved sperm

Asian Journal of Andrology
Abstract Azoospermia is characterized by the absence of sperm in the ejaculate and is categorized into obstructive azoospermia (OA) and nonobstructive azoospermia (NOA). For men with NOA, testicular sperm extraction (TESE) is the only method to obtain sperm for assisted reproductive technology (ART).

eEF1G Orchestrates Translation to Ensure Meiotic Progression in Transcriptionally Quiescent Spermatocytes

Advanced Science, EarlyView.
eEF1G supports translation elongation of meiotic mRNAs in transcriptionally quiescent leptotene and zygotene spermatocytes. Its depletion in germ cells causes meiotic arrest at the zygotene stage, with defective homologous synapsis and unstable recombination intermediates.

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

Animal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

Factors Affecting Outcomes of Salvage Micro Testicular Sperm Extraction Following a Failed Testicular Sperm Extraction

Haseki Tıp Bülteni, 2020
Aim:To investigate the likelihood of sperm retrieval in repeated micro-testicular sperm extraction (micro-TESE) in non-obstructive azoospermia (NOA) patients.Methods:Data of 310 patients, who underwent a micro-TESE procedure at a center experienced in in

Sperm retrieval and fertilization in repeated percutaneous epididymal sperm aspiration [PDF]

Human Reproduction, 1998
Percutaneous epididymal sperm aspiration (PESA) for retrieval of spermatozoa for intracytoplasmic sperm injection (ICSI) is a new simplified technique in the treatment of men with obstructive azoospermia. There has been a fear that the PESA procedure, being blind, could cause damage to the epididymal duct system and make it impossible to retrieve ...

Oocyte–cumulus cell interaction: a key factor in early embryo development

Biological Reviews, EarlyView.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.

Re: Comparison of Microdissection Testicular Sperm Extraction, Conventional Testicular Sperm Extraction, and Testicular Sperm Aspiration for Nonobstructive Azoospermia: A Systematic Review and Meta-Analysis

Journal of Urological Surgery, 2016
In contemporary medicine, testicular sperm extraction (TESE) and using testicular sperm for intracytoplasmic injection is the only fertility treatment in men with nonobstructive azoospermia (NOA).
