The objectives of this non-interventional descriptive study was to determine the variation in serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH) and testosterone along with their ratios, among men having abnormal semen and their possible etiological role in male infertility. The study was carried out in the Reproductive Physiology Department of Public Health Laboratories Division, and National Institute of health (NIH), Islamabad during January 2004 to December 2005. Two hundred fifty married men who had presented with a complaint of infertility and who had an abnormal seminal profile on the basis of their prior semen analysis were included in the study. Subjects were classified as azoospermic (50), oligozoospermic (75), asthenozoospermic (50) and normozoospermic (75). In addition (50) normal male subjects, who were known to have fathered children, were included as controls. LH, FSH and testosterone levels were determined in serum by using enzyme immunoassay (EIA), using state-of-art Elecsys-2010 fully automatic immunology analyzer by Roche Diagnostics (USA). The FSH and LH level indicated inverse/negative correlation to sperm concentration in semen, while decreased testosterone levels were associated with depleted sperm concentration. The findings indicate that not only the altered/disturbed concentrations of gonadotrophins and androgenic hormones are responsible for male sub-fertility but also the disturbances in gonadotrophic: androgenic hormones ratios lead to infertility since these all hormones act synergistically.
这项非干预性描述性研究的目的是确定精液异常男性血清中促黄体生成素(LH)、促卵泡生成素(FSH)和睾酮水平及其比值的变化,以及它们在男性不育症中可能的病因学作用。该研究于2004年1月至2005年12月在伊斯兰堡国家卫生研究所公共卫生实验室分部生殖生理科进行。纳入研究的有250名已婚男性,他们因不育前来就诊,且根据之前的精液分析精液检查结果异常。受试者分为无精子症组(50例)、少精子症组(75例)、弱精子症组(50例)和正常精子症组(75例)。此外,还纳入了50名已知育有子女的正常男性作为对照。采用酶免疫分析法(EIA),使用美国罗氏诊断公司的先进Elecsys - 2010全自动免疫分析仪测定血清中的LH、FSH和睾酮水平。FSH和LH水平与精液中的精子浓度呈负相关,而睾酮水平降低与精子浓度降低有关。研究结果表明,不仅促性腺激素和雄激素浓度的改变/紊乱是男性生育力低下的原因,促性腺激素与雄激素的比值紊乱也会导致不育,因为这些激素都具有协同作用。
