Chromosome studies in 496 infertile males with a sperm count below 10 million/ml
(1984)
Chromosome studies were performed on 106 men with azoospermia and 390 men with oligozoospermia (consistent sperm count below 10 million/ml). Constitutional chromosome abnormalities were found in 14.1% of the azoospermia ...
A prospective study on the predictive value of normal sperm morphology as evaluated by computer (IVOS)
(1996)
Objective: To evaluate the IVOS (Hamilton Thorne Research Version 2.1 Dimension Program, Beverly, MA) system's ability to predict fertilization in vitro in a prospective study. Design: A prospective clinical study. Setting: ...
Effect of reactive oxygen species produced by spermatozoa and leukocytes on sperm functions in non-leukocytospermic patients
(2005)
Objective: To investigate whether there is an impact of different sources of reactive oxygen species (ROS) on sperm functions. Design: Prospective study. Setting: Patients at the Center for Dermatology and Andrology, ...
Effects of folic acid and zinc sulfate on male factor subfertility: A double-blind, randomized, placebo-controlled trial
(2002)
Objective: To study the effects of folic acid and zinc sulfate treatment on semen variables in fertile and subfertile men. Design: Double-blind, placebo-controlled interventional study. Setting: Two outpatient fertility ...
Comparison of three staining methods for the morphological evaluation of human spermatozoa
(2008)
Objective: To compare different staining methods to evaluate human sperm morphology. Design: Prospective study. Setting: Patients at the Departments of Dermatology and Urology, University of Jena, Germany. Patient(s): A ...
Intracytoplasmic sperm injection with testicular spermatozoa in men with azoospermia
(2002)
Purpose: The aim of the study was to gain an insight into the optimal management of the infertile couple with the husband suffering from azoospermia. Methods: One hundred and forty-two intracytoplasmic sperm injection ...
Zona pellucida induced acrosome reaction, sperm morphology, and sperm-zona binding assessments among subfertile men
(2002)
Purpose: The study aimed to evaluate the relationship between the zona pellucida induced acrosome reaction (ZIAR) and (i) percentage normal spermatozoa as well as (ii) sperm-zona pellucida binding potential among men ...
Seasonal changes in human sperm chromatin condensation
(2001)
Purpose: The aim of this study was to investigate possible seasonal changes in human sperm parameters, especially chromatin condensation. Method: In a first run, 3155 patients attending the andrological outpatient clinic ...
Morphological sperm alternations in different types of prostatitis
(2003)
The possible negative effect of the chronic pelvic pain syndrome (CPPS) on semen parameters and especially sperm morphology is still a controversial matter. The aim of this study was therefore to investigate if different ...
