Infertility affects 13-18% of couples and growing evidence from clinical and epidemiological studies suggests an increasing incidence of male reproductive problems. The pathogenesis of male infertility can be reflected by defective spermatogenesis due to pituitary disorders, testicular cancer, germ cell aplasia, varicocele and environmental factors or ...

Journal of Urology, 2007
We assessed male infertility and its treatment in the United States by identifying trends in the use of health care resources and estimating the economic impact of such care.The analytical methods used to generate these results were previously described.Inpatient hospitalizations for male infertility were relatively few with an overall rate of 0.9/100 ...

Immunobiology of male infertility
Human Reproduction, 1988Experimental and clinical data reported in the literature emphasize the important role that immune factors may play in the genesis of male infertility even if many problems still remain to be solved. Auto or homo-sensitization in animals (and in male volunteers) can be obtained with testicular homogenate or epididymal spermatozoa and complete Freund's ...

The microbiome of the infertile male
Current Opinion in Urology, 2020Purpose of review Contrary to historic dogma, many tissues and organs in the human body contain a resident population of bacteria, fungi, and viruses collectively known as the microbiome. The microbiome plays a role in both homeostatic symbiosis and also pathogenic dysbiosis in a wide array of diseases. Our understanding of the

Environmental contaminants and male infertility: Effects and mechanisms
Andrologia, 2020The escalating prevalence of male infertility and decreasing trend in sperm quality have been correlated with rapid industrialisation and the associated discharge of an excess of synthetic substances into the environment. Humans are inevitably exposed to

Salicylazosulfapyridine and male infertility
European Journal of Obstetrics & Gynecology and Reproductive Biology, 1981Recently, several reports have suggested that salicylazosulfapyridine causes a reduction in semen quality in patients with ulcerative colitis. After withdrawal of the drug pregnancies have been reported. The aim of this report is to offer additional data to the discussion on the deleterious effect of salicylazosulfapyridine on semen quality.

Abstract In the follicles of the mammalian and amphibian ovary, oocyte maturation is arrested at the prophase of the first meiotic division. Prior to ovulation, oocytes re-enter the cell cycle, complete the meiotic division and extrude the first polar body.
