Comparative Evaluation of Two Microfluidic Sperm Sorting Devices: Laboratory Assessment of Sperm Quality and Retrospective Analysis of Embryological Outcomes Following Intracytoplasmic Sperm Injection

Reproductive Medicine and Biology, Volume 25, Issue 1, January/December 2026.
ABSTRACT Purpose Density gradient centrifugation (DGC) enriches motile sperm but may increase sperm DNA fragmentation (SDF), whereas microfluidic sperm sorting devices, such as ZyMōt and CA0, enable centrifugation‐free selection with lower SDF. Direct comparisons are limited, and their relative clinical efficacy remains unclear.

Meiotic outcome in two carriers of Y autosome reciprocal translocations: selective elimination of certain segregants [PDF]

, 2017
BACKGROUND: Reciprocal Y autosome translocations are rare but frequently associated with male infertility. We report on the meiotic outcome in embryos fathered by two males with the karyotypes 46,X,t(Y;4)(q12;p15.32) and 46,X,t(Y;16)(q12;q13).

Testicular Biopsy in Azoospermia and Severe Oligozoospermia [PDF]

Archives of Andrology, 1984
The continued experience of testicular biopsy application in 861 cases of azoospermia and 152 cases of severe oligospermia is reported adding to the previously published cases of 1075 patients with azoospermia. The most common finding in the whole series was that of normal testis denoting obstruction (48%), while among cases of functional azoospermia ...

Impact of age at first visit on glycolipid metabolism, bone metabolism, and fertility potential in patients with Klinefelter syndrome

Andrology, Volume 14, Issue 1, Page 122-131, January 2026.
Abstract Background Classic Klinefelter syndrome (KS) is characterized by one extra X chromosome (47, XXY), leading to hypergonadotropic hypogonadism and higher risk of alterations in glycolipid homeostasis, cardiovascular diseases, and low bone mineral density. Most frequently, KS is diagnosed in adulthood because of infertility.

Obesity and Increased Risk for Oligozoospermia and Azoospermia [PDF]

Archives of Internal Medicine, 2012
The global obesity epidemic parallels a decrease in male fertility. Yet, the association between body mass index (BMI) and sperm parameters remains controversial. A negative correlation between BMI and sperm concentration or total sperm count (TSC) was shown by several reports,1, 2 but not documented by others.3, 4 The purpose of this report was to ...
