Implantation sites after embryo transfer into the central area of the uterine cavity
(2006-10-01)
A total of 63 pregnancies (47 singleton, 15 twin, 1 triplet) from intracytoplasmic sperm injection cycles were analysed. In all embryo transfers, the catheter was introduced into the endometrial cavity guided by abdominal ...
Sperm proteomics: potential impact on male infertility treatment
(Taylor & Francis Ltd, 2016)
Spermatozoa are unique cells that have highly compact DNA, motility (and hypermotility) patterns, a specific morphology, localized mitochondria and an apical acrosome. They are the end product of a dynamic process termed ...
Ultrastructure of spermatozoa of orsolobidae (Haplogynae, Araneae) with implications on the evolution of sperm transfer forms in Dysderoidea
(Wiley, 2014-11)
Haplogynae are highly diverse with respect to the primary male genital system and sperm characteristics. Additionally, all sperm transfer forms (STF) known for spiders are present. Besides individually transferred sperm ...

(2021-07-19)
STUDY QUESTION: Can sperm donation increase live birth rates following ICSI in advanced maternal age (AMA) patients? SUMMARY ANSWER: Sperm donation increases the live birth rate in AMA ICSI cycles. WHAT IS KNOWN ALREADY: ...
Sperm motility and lipid composition in internally fertilizing ocellate river stingray Potamotrygon motoro
(Elsevier B.V., 2019-05-01)
All extant groups of Elasmobranches have internal fertilization and the structure of the male reproductive organs is very specific: sperm passes from the internal organs via the cloaca, but the male copulating organ (clasper) ...
Mathematical Prediction of Cooling Rates during Cryopreservation of Reproductive Cells in Liquid Nitrogen
(Nova Science Publishers, 2015)
Liquid nitrogen is one of the cryogenic fluids most used for cryopreservation of animal germoplasm; low temperature preservation of oocytes, sperm and embryos is a fundamental cornerstone of assisted reproductive technologies. ...
How important are internal temperature gradients in french straws during freezing of bovine sperm in nitrogen vapor?
(Cryo Letters, 2013-03)
The subject of present work was to predict internal temperature gradients developed during freezing of bovine sperm diluted in extender, packaged in 0.5 ml French plastic straws and suspended in static liquid nitrogen vapor ...
Differences in sperm migration through cervical mucus in vitro relates to sperm colonization ofthe oviduct and fertilizing ability in goats
(ELSEVIER SCIENCE INC, 2002)
Sperm migration in estrous cervical mucus can be used to measure the ability of spermatozoa to migrate through the genital tract, The relationship of this test with the sperm colonization of the isthmus, and its impact on ...
