Cytoplasmic droplets on boar sperm cells
any veterinarians and AI stud managers have inquired about the significance of cytoplasmic droplets on boar sperm cells. I currently advocate using ejaculates for artificial insemination (AI) which have fewer than 20% morphologically abnormal sperm, with no more than 15% attributable to cytoplasmic droplets. There is, however, little published research on cytoplasmic droplets and their effect o...
متن کاملP-14: The Effects of Depression on Reduced Sperm Motility in Male Rats
Background: Infertility is a problem for 15 to 30% couples. Male infertility may be a result of insufficient number of sperms and poor motility. Spermatozoon consists of a head,midpiece and tail. The long tail consist micro-tubules that from part of the propulsion system of the spermatozoon. Motility of sperm is the result of relation between ATP,micro-tubules and dynein. Depression is one of t...
متن کاملKobe earthquake and reduced sperm motility.
We investigated a possible relationship between the Kobe earthquake (January 17, 1995) and the quality of semen. We assessed sperm concentration and motility of 27 male patients who had a concentration of more than 30 million/ml and >40% sperm motility within 5 months before the earthquake. Twelve male patients from districts with a magnitude of <4 on the Richter scale showed no difference in s...
متن کاملCytoplasmic droplets are normal structures of human sperm but are not well preserved by routine procedures for assessing sperm morphology.
BACKGROUND There is a discrepancy between the use of terminology employed by clinicians and basic scientists concerning the cytoplasmic droplets of sperm. Most clinicians consider their presence on sperm to be indicative of abnormal sperm, whereas basic scientists consider them to be attributes of normal sperm. METHODS The presence of cytoplasmic droplets on human sperm was examined using con...
متن کاملThyroxin Is Useful to Improve Sperm Motility
Objective 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 enrichment method like “swim-up” in comparison with the available one, pentoxifylline. MaterialsAndMethods This is an experimental study. A total of 50 patients were recruited, followed by infertility consultation. Conventional sper...
