Objective: To evaluate agreement of conventional sperm analysis with computer-aided semen analysis (CASA) regarding concentration, motility, and morphology using samples from infertile men.
Materials And Methods: In this study a total of 195 male partners of couples who underwent evaluation of infertility were included. All semen samples were examined by conventional method and CASA in terms of morphology, motility, and concentration. Pearson correlation analysis and the Bland-Altman method were used to assess correlation and agreement between conventional semen analysis and CASA measurements.
Results: When the two methods were compared in terms of concentration, motility, and morphology, there was a statistically significant correlation in all variables. The best correlation was obtained for sperm concentration. However, there was a poor correlation for sperm morphology between conventional method and CASA. Sperm concentration and morphology obtained by CASA were 14% and 87% lower, respectively; motility was 21% higher than the conventional method.
Conclusion: Although CASA systems are objective and rapid, they should be evaluated in terms of cost-effectiveness, however they may be useful in over-loaded assisted reproductive technique (ART) clinics.

Extracellular vesicles in seminal plasma of Sahiwal cattle bulls carry a differential abundance of sperm fertility-associated proteins for augmenting the functional quality of low-fertile bull spermatozoa.

Poor male fertility significantly affects dairy production, primarily due to low conception rates (CR) in bulls, even when cows are inseminated with morphologically normal sperm. Seminal plasma is a key factor in evaluating the fertilizing ability of bull semen. The extracellular vesicles (EVs) in seminal plasma contain fertility-associated proteins like SPAM1, ADAM7, and SP10, which influence sperm function and fertilizing potential.

LCTs may demonstrate various clinical manifestations - from asymptomatic intratesticular swelling through nonspecific symptoms such as loss of libido, impotence or infertility, up to feminizing or virilizing syndromes due to hormonal activity of the tumor. This article presents a case of Leydig cell tumor that was associated with azoospermia what have rarely been reported worldwide.

Ensuring boar sperm quality before insemination is crucial for maximizing field fertility and efficient pig production. The computer-assisted sperm analysis (CASA) and fluorescence probes combined with flow cytometry (FC) are commonly used techniques for evaluating sperm kinematics and functions, closely related to animal fertility. However, their high cost and complex operations make it challenging to apply them in laboratories or pig breeding farms with limited resources.

Purpose: Prior sperm DNA fragmentation index (DFI) thresholds for diagnosing male infertility and predicting assisted reproduction technology (ART) outcomes fluctuated between 15 and 30%, with no agreed standard. This study aimed to evaluate the impact of the sperm DFI on early embryonic development during ART treatments and establish appropriate DFI cut-off values.
Methods: Retrospectively analyzed 913 couple's ART cycles from 2021 to 2022, encompassing 1,476 IVF and 295 ICSI cycles, following strict criteria.

While there are several easy-to-use reversible female contraceptives, little is available for men. Introduction of novel, cost-effective male contraceptives could have important downstream global health and economic benefits. Currently, nearly half of all pregnancies globally are unintended, with many resulting in unsafe abortions, a significant burden for women and families in many countries.
