Cryopreservation of testicular and epididymal sperm: techniques and clinical outcomes of assisted conception [PDF]

Clinics, 2013
The introduction of the technique of intracytoplasmic sperm injection to achieve fertilization, especially using surgically retrieved testicular or epididymal sperm from men with obstructive or non-obstructive azoospermia, has revolutionized the field of

Surgical Sperm Retrieval Techniques for Assisted Reproductive Technology

Düzce Tıp Fakültesi Dergisi, 2022
Intracytoplasmic sperm injection provides in vitro fertilization for many infertility conditions. It is also an important treatment option for fertilization in azoospermic men. Sperm production in azoospermic male testicles is possible. In these patients,

The Klinefelter Syndrome and Testicular Sperm Retrieval Outcomes

Genes, 2023
Klinefelter syndrome (KS), caused by the presence of an extra X chromosome, is the most prevalent chromosomal sexual anomaly, with an estimated incidence of 1:500/1000 per male live birth (karyotype 47,XXY).

Anti-Müllerian hormone predicts positive sperm retrieval in men with idiopathic non-obstructive azoospermia—findings from a multi-centric cross-sectional study

Human Reproduction, 2023
STUDY QUESTION Is it possible to identify a reliable marker of successful sperm retrieval (+SR) in men with idiopathic non-obstructive azoospermia (iNOA) undergoing microdissection testicular sperm extraction (mTESE)?

Nomogram based on a circular RNA biomarker for predicting the likelihood of successful sperm retrieval via microdissection testicular sperm extraction in patients with idiopathic non-obstructive azoospermia

Frontiers in Endocrinology, 2023
Background Many circular RNAs (circRNAs) are specifically expressed in the testes and seminal plasma of patients with non-obstructive azoospermia (NOA), highlighting them as potential predictors of microdissection testicular sperm extraction (micro-TESE)

Seminal extracellular vesicle sncRNA sequencing reveals altered miRNA/isomiR profiles as sperm retrieval biomarkers for azoospermia

Andrology, 2023
Non‐invasive molecular biomarkers for classifying azoospermia by origin into either obstructive or non‐obstructive/secretory azoospermia, as well as for inferring the spermatogenic reserve of the testis of non‐obstructive/secretory azoospermia patients ...

Testosterone to Luteinizing Hormone Ratio as a Potential Predictor of Sperm Retrieval in Non-Obstructive Azoospermia Patients

Yonsei medical journal, 2023
Purpose This study assessed the outcomes of microsurgical testicular sperm extraction (mTESE) and potential preoperative predictors of sperm retrieval (SR) in patients with non-obstructive azoospermia (NOA). Materials and Methods Clinical data of 111 NOA

Development of a predictive model for increasing sperm retrieval success by microdissection testicular sperm extraction in patients with nonobstructive azoospermia

Asian Journal of Andrology, 2023
Microdissection testicular sperm extraction (micro-TESE) is widely used to treat nonobstructive azoospermia. However, a good prediction model is required to anticipate a successful sperm retrieval rate before performing micro-TESE.

Cryptozoospermia: Should we use ejaculated sperm or surgically retrieved sperm for assisted reproductive technology?

Reproductive Medicine and Biology, 2023
Purpose In cryptozoospermic subjects, it may often may be difficult to secure motile sperm for assisted reproductive technology (ART). We examined the results of ART with frozen thawed ejaculated sperm in cryptozoospermic subjects and evaluated whether ...
