The Epidemiology of Male Infertility
Urologic Clinics of North America, 2014The purpose of this review is to integrate understanding of epidemiology and infertility. A primer on epidemiologic science and an example disease for which the design of epidemiologic investigations is readily apparent are provided.

Molecular and Cellular Endocrinology, 1998
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.

British medical journal, 2010
Few NPs are exposed to the topic of male infertility during the course of their training. There are medical and surgical treatment options for many of the most common diagnoses that contribute to decreased fertility in men. Recognizing these etiologies can help patients receive cost-effective treatment.

Cytokines and male infertility
European Cytokine Network, 2018Many male infertility cases have no apparent cause, being characterized as idiopathic. Both inflammation and obesity have long been associated with infertility. On one hand, inflammation, such as orchitis and male accessory gland infections (MAGIs), are regulated by inflammatory cytokines.

Major difficulties exist in the accurate and meaningful diagnosis of male reproductive dysfunction, and our understanding of the epidemiology and etiology of male infertility has proven quite complex.The numerous spermatozoa produced in mammals and other species provides some degree of protection against adverse environmental conditions represented by ...

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

Contraception, 2005
Male factor infertility is a general term that describes a situation in which the inability to conceive is associated with an alteration identified in the male partner. This dysfunction may be associated with low sperm concentration (oligozoospermia), poor sperm motility (asthenozoospermia) or abnormal sperm morphology (teratozoospermia); however ...

The Genetics of Male Infertility
Seminars in Reproductive Medicine, 2009Developments in genomic medicine will likely explain much of what is now considered idiopathic male infertility. Indeed, our understanding of the genetic defects that cause infertility is no longer confined to chromosomal aneuploidies (e.g., Klinefelter syndrome) and single-gene defects (cystic fibrosis and congenital absence of the vas deferens).

Cytomegalovirus and male infertility.
Annales de biologie clinique, 1987Male infertility may be due to a multiplicity of etiologic factors. In this study we have investigated the presence of cytomegalovirus (CMV) in 150 infertile men (selected after the exclusion of other etiopathogenic factors of infertility) and 80 subjects screened for pre-marriage consult.
