Sperm morphology, ultrastructure, and motility in pikeperch Sander lucioperca (Percidae, Teleostei) associated with various activation media

Spermatozoa morphology, ultrastructure, and spermatozoa motility traits were studied in pikeperch (Sander lucioperca) after activation in various media (AM 1 – 45mM NaCl, 5mM KCl, 20mM Tris, pH 8.5; AM 2 – 100mM sucrose, 20mM Tris, pH 8.5; AM 3 – 100mM sucrose, 1mM CaCl2, 20mM Tris, pH 8.5) during a 48-hour storage period. The spermatozoon was acrosomeless and differentiated into a spherical nu...

Sperm Cryopreservation of Two European Predator Fish Species, the Pikeperch (Sander lucioperca) and the Wels Catfish (Silurus glanis)

Correlation between sperm ultrastructure in infertile patients with abnormal sperm morphology and DNA damage.

This study explored the correlation between sperm ultrastructure in infertile patients with abnormal sperm morphology and DNA damage. Three unusual sperm morphologies were selected for the experimental group namely case 1 (95% headless sperm), case 2 (98% headless sperm), and case 3 (100% headless sperm), and the control group consisted of 2 subjects (20 and 15% headless sperm). For case 1, the...

THE CORRELATION BETWEEN SPERM MORPHOLOGY AND MOTILITY IN FERTILE AND INFERTILE MEN

The swim-up procedure was used to collect a sperm fraction with improved motility and normal morphology from fertile and infertile semen samples. The untreated and swim-up fractions were analyzed with the Hamilton-Thorn Motility Analyser. Comparisons were made to see the effect of this sperm selection technique on sperm motility and morphology. They were then examined by transmission elect...

Principles of pikeperch (Sander lucioperca) larviculture

Pikeperch (Sander lucioperca) is a species with high nutritional, ecological and commercial values which is endemic in Iran, but its natural stocks are endangered during recent years. Therefore, Iranian Fisheries Organization as the main responsible organization for preservation of aquatic natural stocks of the country planned to stock rehabilitation of this species since 1989. This program had...
