Cells, 2021 We present a new method for the selection of individual sperm cells using a microfluidic device that automatically traps each cell in a separate microdroplet that then individually self-assembles with other microdroplets, permitting the controlled ...

Journal of Applied Animal Research, 2023 We aimed to test the common belief, that as the sperm cell is the smallest cell in an organism and, therefore, it contains a small amount of intracellular water, the intracellular ice should not strongly affect the sperm cell during the cryopreservation.

The Effect of Oxidative Stress and Dietary Vitamin E Supplementation on Fresh Sperm Quality of Ross 308 Broiler Breeder Roosters [PDF]
پژوهشهای علوم دامی ایران, 2023 Introduction[1]: Oxidative stress is an imbalance between oxidants and antioxidants at the cellular level which leads to the condition of infertility in male.

Acta Medica Bulgarica, 2023 Abstract A major factor affecting male fertility is excessive death of germ cells, both immature germ cells and mature spermatozoa. It can be due to various factors causing testicular and/or post-testicular damage, such as infections, obstructive conditions, toxins, oxidative stress, hormonal imbalance, hyperthermia, and anti-sperm ...

Not all sperm are equal: functional mitochondria characterize a subpopulation of human sperm with better fertilization potential. [PDF]
PLoS ONE, 2011 Human sperm samples are very heterogeneous and include a low amount of truly functional gametes. Distinct strategies have been developed to characterize and isolate this specific subpopulation.

Effect of macrophages in semen on sperm quality
Reproductive Biology and Endocrinology, 2021 Background This was a cross-sectional study in China which analyzed the levels of macrophages (Mφ) in semen and evaluated the influence of Mφ levels in semen on sperm quality. Methods The subjects involves 78 males, 25- to 35-year old.

Characterization of eight novel proteins with male germ cell-specific expression in mouse
Reproductive Biology and Endocrinology, 2008 Background Spermatogenesis and fertilization are highly unique processes. Discovery and characterization of germ cell-specific genes are important for the understanding of these reproductive processes.
