Leucospermia and Male Fertility [PDF]
Archives of Andrology, 1980 The evaluation of smears of normozoospermic men showed a clear leucospermia in 15% of the patients. There was a slight motility inhibition of the spermatozoa and head-to-head agglutination in the direct surroundings of the leucocytes. Phagocytosis of sperm heads by granulocytes was also evident.

Expression of a catalytically inactive mutant form of glutathione peroxidase 4 (Gpx4) confers a dominant-negative effect in male fertility. [PDF]
, 2015 The selenoenzyme Gpx4 is essential for early embryogenesis and cell viability for its unique function to prevent phospholipid oxidation. Recently, the cytosolic form of Gpx4 was identified as an upstream regulator of a novel form of non-apoptotic cell ...

The impact of mitochondrial impairments on sperm function and male fertility: a systematic review
Reproductive Biology and EndocrinologyBesides adenine triphosphate (ATP) production for sustaining motility, the mitochondria of sperm also host other critical cellular functions during germ cell development and fertilization including calcium homeostasis, generation of reactive oxygen ...

Thyroxin Is Useful to Improve Sperm Motility [PDF]
International Journal of Fertility and Sterility, 2016 Background The aim of this study was to evaluate the non-genomic action of thyroxin on sperm kinetic and its probable use to improve sperm recovery after applying an en- richment method like “swim-up” in comparison with the available one, pentoxifylline.
