The male contributes significantly, directly accounting for 30–35% and up to 52% of total couple infertility, affecting approximately 7–8% of all men. This work aims to present, in a didactic and objective way, a standardization of the initial steps toward a thorough evaluation of subfertile and infertile men. We have focused on the evaluation of initial management, emphasizing the need for a comprehensive evaluation that includes a detailed history, physical examination, and semen analysis as the golden triple helix of basic evaluation of the infertile male. General and genital physical examinations are highly valuable due to the wealth of information they provide, from potential diagnoses to pregnancy prognoses. Comprehensive and quality-controlled semen analysis provides reliable information as a baseline test to evaluate the patency of the reproductive tract and to evaluate basic sperm parameters and fertility potential. However, it is not a fertility determinant and should preferentially be complemented with sperm functional tests. like biomarkers of oxidative stress, sperm immaturity and DNA fragmentation. Most cases of infertility require evaluation by a specialist in andrology, nonetheless the understanding and rationale of the initial assessment of the infertile male can be undertaken by non-specialists, thus improving the care and counseling of couples facing this troubling issue and avoiding unnecessary use of assisted reproductive technologies (ART) since most cases of male infertility can be treated and reversed by medical or surgical interventions, and the fertility status can be restored. The ultimate goal is to achieve natural pregnancy, the use of ART should not be the initial offered resource.</div></div>","PeriodicalId":8318,"journal":{"name":"Archives of Medical Research","volume":"55 8","pages":"Article 103139"},"PeriodicalIF":4.7,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142792880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Presently, laparoscopic robotic assisted surgery is used for various benign and malignant gynecological procedures, including fertility enhancing procedures. Laparoscopic Robot-assisted surgery is superior to traditional open procedures with regards to post-surgical hospital stay and blood loss; however, the difference is comparable to laparoscopic surgery. Regarding operative times, the results have been inconsistent due to variations in surgeons’ experience. The primary drawbacks of robotic systems are their high installation and maintenance costs and historical lack of tactile feedback; however, this has been overcome by the most recent evolution of robotic systems. Along with the major advances in cancer therapy, the number of female cancer survivors of reproductive age has dramatically increased. Consequently, fertility preservation and fertility enhancement have gained more emphasis in reproductive surgery in the last decade. A broad range of surgical procedures such as tubal reanastomosis, myomectomy, treatment of deep infiltrating endometriosis, ovarian transposition, radical trachelectomy, and ovarian transplantation has been introduced to restore or preserve fertility using Laparoscopic Robot-assisted surgery.
