Development of a nomogram for sperm retrieval at microTESE for idiopathic non‐obstructive azoospermia in a multi‐center cohort study

open access: yesAndrology, EarlyView.
Abstract Background Non‐obstructive azoospermia (NOA) affects approximately 10% of infertile men and represents a major challenge in assisted reproductive technology (ART). A model that includes histological variants could be helpful in predicting sperm retrieval rate (SRR) after microdissection testicular sperm extraction (mTESE) in patients affected ...

Case report: Comprehensive evaluation and management of male infertility with complete AZFC microdeletion and undescended testicle

open access: yesUrology Case Reports
This case report presents a 31-year-old male patient with primary infertility, a unilaterally undescended testicle, and a complete AZFc microdeletion. Despite failed attempts at testicular sperm extraction, the patient underwent successful microscopic ...

Relationship between sperm parameters and intracytoplasmic sperm injection outcome

open access: yesMiddle East Fertility Society Journal, 2015
Objectives: With the adventure of intracytoplasmic sperm injection (ICSI) technique, great progresses have developed in the treatment of infertility. Concentration on the properties of male’s gamete has been encouraged by the increasing concerns about ...

Use of testicular sperm in couples with SCSA-defined high sperm DNA fragmentation and failed intracytoplasmic sperm injection using ejaculated sperm

open access: yesAsian Journal of Andrology, 2020
Sperm DNA fragmentation (SDF) has been linked with male infertility, and previous studies suggest that SDF can have negative influence on pregnancy outcomes with assisted reproduction.

Microfluidic Intracytoplasmic Sperm Injection (MICSI): A Novel Platform for Sperm Isolation, Selection, and Injection Into Oocytes

open access: yesAndrology, EarlyView.
ABSTRACT Background Infertility is a pressing global health concern, affecting one in six couples worldwide. The failure rate for assisted reproductive technologies (ART) cycles remains at approximately 78%, with limited improvements often attributed to a lack of technological innovation.

Changes in Sperm Motility and Capacitation Induce Chromosomal Aberration of the Bovine Embryo following Intracytoplasmic Sperm Injection.

open access: yesPLoS ONE, 2015
Intracytoplasmic sperm injection (ICSI) has become the method of choice to treat human male infertility. One of the outstanding problems associated with this technique is our current lack of knowledge concerning the effect of sperm capacitation and ...

Fertilization and early embryology: The chromosomal complements of multipronuclear human zygotes resulting from intracytoplasmic sperm injection [PDF]

open access: yes, 2017
Implementation of intracytoplasmic sperm injection (ICSI) in human in-vitro fertilization (IVF) has highlighted the need for information about the risk of nuclear spindle damage caused by this procedure.

Computer‐Assisted Sperm Analysis (CASA) Versus Manual Evaluation and the Clinical Significance of Sperm Hyperactivated Motility

open access: yesAndrology, EarlyView.
Abstract Background Semen analysis remains the first‐line diagnostic test for male infertility, although it is affected by operator subjectivity. Computer‐assisted sperm analysis (CASA) is proposed to improve objectivity; however, its accuracy and clinical relevance remain uncertain.

Sperm nuclear DNA damage and altered chromatin structure: effect on fertilization and embryo development [PDF]

open access: yes, 2017
In the first part of this report we investigate whether chromatin anomalies in human spermatozoa can influence fertilization after intracytoplasmic sperm injection (ICSI).
