Comparative analysis of surgically retrieved sperms in cases of obstructive and nonobstructive azoospermia treated for infertility

Journal of Human Reproductive Sciences, 2020
Background: Azoospermia is a highly evolving subject in the last few decades. In the past, use of donor sperm was the only option providing a realistic chance of conception for couples affected by azoospermia.

Dynamics of 5-methylcytosine and 5-hydroxymethylcytosine during pronuclear development in equine zygotes produced by ICSI [PDF]

, 2017
Background: Global epigenetic reprogramming is considered to be essential during embryo development to establish totipotency. In the classic model first described in the mouse, the genome-wide DNA demethylation is asymmetric between the paternal and the ...

Histology and sperm retrieval among men with Y chromosome microdeletions

Translational Andrology and Urology, 2021
In this review of Y chromosome microdeletions, azoospermia factor (AZF) deletion subtypes, histological features and microTESE sperm retrieval rates are summarized after a systematic literature review. PubMed was searched and papers were identified using

Prediction Models for Successful Sperm Retrieval in Patients with Non-Obstructive Azoospermia Undergoing Microdissection Testicular Sperm Extraction: Is There Any Room for Further Studies?

Journal of Clinical Medicine, 2021
Several prediction models for successful sperm retrieval (SSR) in patients with azoospermia due to spermatogenic dysfunction (also termed non-obstructive azoospermia—NOA) have been developed and published in the past years, however their resulting ...

Sperm fine-needle aspiration (FNA) mapping after failed microdissection testicular sperm extraction (TESE): location and patterns of found sperm

Asian Journal of Andrology, 2019
We sought to evaluate the ability of fine-needle aspiration (FNA) mapping to find sperm and to guide sperm retrieval after failed microdissection testicular sperm extraction (micro-TESE) in nonobstructive azoospermic men.

Contribution of serum anti-Müllerian hormone in the management of azoospermia and the prediction of testicular sperm retrieval outcomes: a study of 155 adult men

Basic and Clinical Andrology, 2021
Background Testicular sperm extraction (TESE) is the method of choice for recovering spermatozoa in patients with azoospermia. However, the lack of reliable biomarkers makes it impossible to predict sperm retrieval outcomes at TESE.

Updates on sperm retrieval techniques.

Translational andrology and urology, 2014
In the most extreme form of male infertility, the male partner is azoospermic. The advent of in vitro fertilization (IVF)-intracytoplasmic sperm injection (ICSI) has revolutionized our ability to treat azoospermia in both obstructive and non-obstructive cases.

Clinical parameters as predictors for sperm retrieval success in azoospermia: experience from Indonesia [version 1; peer review: 1 approved, 1 approved with reservations]

F1000Research, 2023
Background Azoospermia is the most severe type of male infertility. This study aimed to identify useful clinical parameters to predict sperm retrieval success.

Comparison of sperm retrieval and reproductive outcome in azoospermic men with testicular failure and obstructive azoospermia treated for infertility

Asian Journal of Andrology, 2014
We assessed the rates of sperm retrieval and intracytoplasmic sperm injection outcomes, including the neonatal profile of infants conceived, in men with testicular failure.
