In the modern era, contemporary management of male infertility has undergone groundbreaking changes with the introduction of new concepts, advanced testing, and therapeutic interventions. As practicing gynecologists are often the first physicians who encounter an infertile couple, it is essential that these clinicians are continuously updated about the new pearls and pitfalls of male infertility management. Semen analysis is commonly ordered by gynecologists. In 2010, the WHO released new cutoff reference values for the semen parameters adopting novel methodology, which has incited much debate. Reference values have been lowered in comparison with previous standards, with a direct clinical implication in decision-making strategies. Specialized sperm-function tests, such as sperm oxidative stress and sperm chromatin integrity assessments, became clinically available, thus offering an opportunity to better understand sperm dysfunctions concealed during routine semen analysis. Furthermore, the initial counseling of azoospermic men by an andrologically well educated gynecologist may alleviate the misconception and distress surrounding the false belief of sterility, and will clarify the available options of percutaneous and microsurgical sperm-retrieval techniques and assisted conception outcome. Regarding varicocele, which is commonly seen in infertile males, it is now clear that the best treatment option for infertile men with clinical varicocele is the microsurgical vein ligation. Natural conception is significantly improved after varicocelectomy, and recent data suggest that such treatment optimizes reproductive outcome of couples undergoing ICSI or micro-TESE sperm retrieval. Lastly, new therapeutic interventions, including oral antioxidant therapy and lifestyle modifications, have gained increasing attention, as they aid in alleviating male infertility.
在现代,随着新概念的引入、先进检测方法和治疗干预手段的出现,男性不育症的当代管理发生了突破性变化。由于执业妇科医生往往是最先接触到不育夫妇的医生,因此这些临床医生不断了解男性不育症管理的新要点和陷阱至关重要。精液分析是妇科医生常用的检查项目。2010年,世界卫生组织采用新方法发布了精液参数的新临界参考值,这引发了诸多争议。与先前标准相比,参考值有所降低,这对决策策略有直接的临床影响。专门的精子功能检测,如精子氧化应激和精子染色质完整性评估,已在临床上可用,从而为更好地了解常规精液分析中隐藏的精子功能障碍提供了机会。此外,由男科知识丰富的妇科医生对无精子症男性进行初步咨询,可能会减轻围绕不育错误观念的误解和痛苦,并将阐明经皮和显微外科精子采集技术及辅助受孕结果的可用选择。关于精索静脉曲张,这在不育男性中很常见,现在很清楚,对于患有临床精索静脉曲张的不育男性,最佳治疗选择是显微外科静脉结扎术。精索静脉曲张切除术后自然受孕显著改善,最近的数据表明,这种治疗可优化接受卵胞浆内单精子注射(ICSI)或显微睾丸精子提取术(micro-TESE)的夫妇的生殖结局。最后,新的治疗干预措施,包括口服抗氧化剂治疗和生活方式改变,越来越受到关注,因为它们有助于缓解男性不育症。
