World Health Organization reference values for human semen characteristics.
BACKGROUND Semen quality is taken as a surrogate measure of male fecundity in clinical andrology, male fertility, reproductive toxicology, epidemiology and pregnancy risk assessments. ReferenceExpand

  • Asian journal of andrology
  • 2011
The potential of spermatozoa to become motile during post-testicular maturation, and the relationship between the cytoplasmic droplet and fertilizing capacity are reviewed. Post-testicular maturationExpand

Epididymal markers in human infertility.
Alpha-glucosidase, glycerophosphocholine, and L-carnitine were measured in sperm-free seminal plasma to determine whether these markers reflected the epididymal function of men attending anExpand

Clinical experience with azoospermia: aetiology and chances for spermatozoa detection upon biopsy.
The clinical workup of the infertile male with azoospermia aims at determining the aetiology and estimating the chances of finding spermatozoa by testicular sperm extraction (TESE). To establishExpand

Organization of tubules in the human caput epididymidis and the ultrastructure of their epithelia.
The structure of the human caput epididymidis was examined by gross morphological and light and electron microscopic techniques. There were at least seven types of tubules, each characterized by aExpand

Infertile spermatozoa of c-ros tyrosine kinase receptor knockout mice show flagellar angulation and maturational defects in cell volume regulatory mechanisms.
Homozygous c-ros knockout male mice that lack prepubertal differentiation of the epididymal initial segment are healthy but sterile, despite normal sperm production and mating. Detailed computerizedExpand

Acquisition of volume regulatory response of sperm upon maturation in the epididymis and the role of the cytoplasmic droplet
In certain cases of infertility in domestic species, and in the homozygous c‐ros tyrosine kinase knockout mouse, males are infertile as a result of unopposed sperm swelling. This induces flagellarExpand

High-b-value diffusion-weighted MR imaging of adult brain: image contrast and apparent diffusion coefficient map features.
BACKGROUND AND PURPOSE Recent improvements in MR gradient technology allow significant increases in diffusion weighting without prohibitive signal-to-noise degradation. The purpose of ourExpand

Aquaporins in the human testis and spermatozoa - identification, involvement in sperm volume regulation and clinical relevance.
Despite the high water-permeability of human spermatozoa, little is known about the identity and the role of aquaporins (AQP) in them or germ cells. Using ejaculates from donors, sperm AQPs wereExpand

  • 1998
The interactions between spermatozoa and epididymal secretions are reviewed with respect to the nature of the interactions, the maturity of the spermatozoa and the environment in which spermatozoaExpand
