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

open access: yesAndrology, Volume 14, Issue 5, Page 1202-1208, July 2026.
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 ...

Correlation between Follicular Fluid Fatty Acids and Cell-Free Mitochondrial DNA in Women Undergoing Intra-Cytoplasmic Sperm Injections

open access: yesمجلة كلية الطب
Background: Beta-oxidation of fatty acids takes place in the mitochondria to produce energy. This process is linked to the formation of free radicals. Previous researches propose that some fatty acids may be related to mitochondrial dysfunction, as they

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

open access: yesAndrology, Volume 14, Issue 5, Page 1401-1412, July 2026.
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.

Abnormal cleavage patterns in equine in vitro‐produced embryos lead to higher early pregnancy loss

open access: yesEquine Veterinary Journal, Volume 58, Issue 4, Page 970-980, July 2026.
Summary Background Despite significant advances, in vitro production (IVP) of equine embryos continues to lack standardised embryo classification criteria and is associated with increased rates of early pregnancy loss compared with in vivo‐derived blastocysts.

Effects of cotinine on sperm motility, membrane function, and fertilizing capacity in vitro

open access: yes, 2000
We evaluated the effect of cotinine on sperm fertilizing capacity in vitro. Human spermatozoa were washed and re-suspended in medium containing albumin and various concentrations of cotinine (0, 100, 200, 400, or 800 ng/ml).
