ACUPUNCTURE AND MALE INFERTILITY About male infertility
The clinical definition of male infertility is the presence of abnormal semen parameters in the male partner of a couple who have been unable to conceive after 1 year of unprotected intercourse (Dohle 2010). The World Health Organization defines male factor infertility as the presence of one or more abnormalities in the semen analysis, or the presence of inadequate sexual or ejaculatory functio...
متن کاملEpIdEmIology and aEtIology of cS
cases of endogenous CS are related to excessive adrenocorticotrophin (ACTH) production, most commonly from a pituitary adenoma, or from a non-pituitary tumour (ACTH-dependent CS). Less often endogenous CS is secondary to hyperfunctioning adrenocortical tumours, bilateral adrenal hyperplasia, and/or dysplasia (ACTH-independent CS). Endogenous CS needs to be distinguished from the so-called ‘pseu...
متن کاملRelationship between epidemiological features and aetiology of male infertility as diagnosed by a comprehensive infertility service provider.
This study examined the relationship between demographic features and aetiological causes of male infertility. Primary infertility was the presentation in 78% of patients. The incidence of varicocele was the highest (31%), whereas only 4.6% had vasectomy reversal and 7.4% of men were diagnosed with idiopathic infertility. Using the chi-squared test, there was no significant difference in the in...
متن کاملMale infertility: Y-chromosome deletion and testicular aetiology in cases of azoo-/oligospermia.
The spermatogenesis locus azoospermia factor (AZF) in Yq11 has been delineated into three microdeletion intervals designated as AZFa, AZFb andAZFc. AZFc is the most frequently deleted region. We have studied 270 male infertile patients for various genetic disorders associated with infertile phenotype. In this study, we have presented results of our studies on Y-chromosome deletions, chromosomal...
متن کاملThe role of the testis-specific gene hTAF7L in the aetiology of male infertility.
The X-linked TAF7L gene is homologous to the autosomal transcription factor TAF7. Together with its testis-specific expression pattern, this might point to an important function in spermatogenesis. In order to analyse the involvement of the hTAF7L gene in the aetiology of male infertility, a total of 25 patients with maturation arrest of spermatogenesis have been analysed for the presence of mu...
