Comparison of semen parameters between pregnant and nonpregnant couples with male factor infertility during intrauterine insemination
Male factor semen parameter sperm concentration pregnancy
2010/1/12
Aim: To compare the semen parameters between pregnant and nonpregnant couples with male factor infertility during intrauterine insemination (IUI). Materials and Methods: The study included a total of ...
Treatment of men with idiopathic oligozoospermic infertility using the aromatase inhibitor, testolactone. Results of a double-blinded, randomized, placebo-controlled trial with crossover
men idiopathic oligozoospermic infertility aromatase inhibitor testolactone
2009/2/23
The hypothesis that increased estradiol production may be the cause of impaired spermatogenesis in infertile men with idiopathic oligozoospermia was tested by administering the aromatase inhibitor...
Genetically defined mouse models of male infertility
Genetically defined mouse models male infertility
2009/2/23
The review has four objectives. The first objective is to summarize our studies of gene mutations that induce infertility in male mice. The second objective is to stress the power of mouse genetics ...
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 an infert...
Factors influencing the success of sperm-cervical mucus interaction in patients exhibiting unexplained infertility
cervical mucus penetration sperm movement unexplained infertility hamster oocyte assay
2009/2/23
The factors regulating the success of sperm-cervical mucus interaction in 46 patients exhibiting unexplained infertility were analyzed. Within this group of patients, considerable variation in the d...
Congenital absence of the vasa deferentia presenting with infertility
Congenital absence vasa deferentia presenting infertility
2009/2/20
Congenital absence of both vasa deferentia is not an infrequent cause of sterility. Between April 1975 and December 1981, 11 men out of a total of 749 presenting with infertility were diagnosed as h...
A prospective study of the relationship between semen quality and fertility in cases of unexplained infertility
hamster oocyte penetration sperm motility unexplained infertility
2009/2/20
The male partners of 68 couples exhibiting 5.1 +/- 0.3 (SEM) years of unexplained infertility were assessed using the conventional criteria of semen quality, the movement characteristics of the sper...
Evaluation of oxidative DNA damage in human sperm and its association with male infertility
8-Hydroxydeoxyguanosine spermatozoa infertility
2009/2/18
Recently, there is increasing evidence suggesting that oxidative sperm DNA damage is closely associated with impaired sperm function and male infertility. 8-Hydroxydeoxyguanosine (8-OHdG) is consi...
Oxidative stress and male infertility
Seminal plasma reactive oxygen species antioxidants infertility
2009/2/16
We have studied the activity of substances (superoxide dismutase [SOD], catalase [Cat], malonaldehyde, xanthine oxidase [XO], nitric oxide [NOx]) participating in oxidative stress. Seminal plasma sa...
Role of oxidative stress and antioxidants in male infertility
oxidative stress antioxidants male infertility
2009/2/13
Oxygen toxicity is an inherent challenge to aerobic life, including spermatozoa, the cells responsible for propagation of the species. How this toxicity affects the spermatozoan in its interactions wi...
Soluble Fc gamma RIII（CD16）and immunoglobulin G levels in seminal plasma of men with immunological infertility
Enzyme-linked immunosorbent assay (ELISA) immunosuppression
2009/2/12
Receptors for the Fc region of the immunoglobulin G (IgG) (Fc gamma R) have been recognized as a link between humoral and cellular immune responses. A soluble form of Fc gamma RIII (CD16) has been...
A“miniacrosome”sperm defect causing infertility in two brothers
“miniacrosome”sperm defect infertility brothers
2009/2/7
A sperm defect causing infertility in two brothers is described. The malformation, named the "miniacrosome sperm defect," occurs in the total sperm population. It involves both the nuclei, which ...
Seminal alpha-glucosidase activity as a marker of epididymal pathology in nonazoospermic men consulting for infertility
human epididymis a-glucosidase epididymal markers clinical epididymal abnormalities functional epididymal failure
2009/2/6
Glucosidase (alpha G) activity was measured in sperm free seminal plasma from 1200 patients consulting for primary infertility, in whom clinical examination of epididymides revealed some abnormaliti...
Relationship between seminal white blood cell counts and oxidative stress in men treated at an infertility clinic
Leukocytospermia male infertility semen reactive oxygen
2008/12/29
In semen, granulocytes are major producers of reactive oxygen species (ROS), which can damage sperm. The diagnosis of leukocytospermia is usually based on the World Health Organization (WHO) definitio...
Oxidative stress in normospermic men undergoing infertility evaluation
Oxidative stress normospermic men infertility evaluation
2008/12/26
The purpose of this study was to determine whether normospermic infertile men have high seminal oxidative stress, using 3 measures of oxidative stress: reactive oxygen species (ROS), total antioxidant...
