Changes of Sperm Tail Morphology After Kallikrein Treatment

Effect of curcumin on rat sperm morphology after the freeze-thawing process

Reactive oxygen species (ROS) generation, induced by the cryopreservation process, can be responsible for mammalian sperm damage. Curcumin is known as an effective antioxidant against oxidative stress. The aim of this study was to evaluate the effects of curcumin on sperm count, motility and viability, semen total antioxidant capacity and DNA integrity of rat spermatozoa during semen freeze-tha...

Abnormal sperm morphology

Sperm morphology is unique among the known cells and 3 major parts can be immediately distinguished: head, midpiece and tail. Normal sperm exhibit an oval-shaped head with a regular outline and a cap (acrosome) covering more than one-third of the head surface. The midpiece is slender, less than one third of the width of the head, straight and regular in outline. The tail is slender, uncoiled an...

Evolution of sperm morphology in

The effect of kallikrein on human sperm membrane function.

To illustrate the influence of kallikrein on the hypoosmotic swelling test, 84 human semen samples were classified into 4 groups: normospermia (n = 34, group A), oligospermia (n = 18, group B), asthenospermia (n = 8, group C), and oligoasthenospermia (n = 24, group D). Two aliquots of 0.45 ml were prepared from each specimen in all the groups: one was incubated for 3 hr in a glass tube containi...

Changes in Rat Testis and Sperm Count after Acute Treatment with Sodium Nitrite
