Issued without a dust jacket. -- A structured, evidence-based examination of one of the most complex and frustrating diagnoses in reproductive medicine. Although infertility affects millions globally, up to 30 percent of infertile couples receive no clear diagnosis despite thorough evaluations. This volume bridges clinical experience and scientific insight, addressing both male and female factors potentially contributing to unexplained infertility, and provides guidance for assessment, treatment, and the use of assisted reproductive technologies (ART). The book is divided into six major sections, each elucidating a different aspect of unexplained infertility with direct implications for clinical and laboratory practice. The opening section focuses on definitions and epidemiology, clarifying diagnostic challenges and inconsistencies across male and female presentations. It critically evaluates the controversial 2010 WHO semen criteria, which lowered normal reference values and potentially reclassified many men into the unexplained infertility category. This reframing has significant implications for diagnosis and subsequent care. The second section addresses male pathophysiology, analyzing sperm function beyond standard semen parameters. It presents emerging knowledge about sperm motility, capacitation, DNA integrity, oxidative stress, immune responses, and environmental toxin exposure. These chapters emphasize that many men with normal semen profiles may still harbor hidden dysfunctions undetectable by routine tests. Discussions on genetic markers and sperm bioenergetics also show how molecular diagnostics are beginning to reclassify idiopathic cases into identifiable subtypes, reshaping future diagnostic protocols. The female pathophysiology section highlights the nuanced contributions of cervical, endometrial, tubal, and oocyte-level abnormalities. It reviews how conditions like subtle endometriosis, impaired endometrial receptivity, vaginal pH shifts, and oxidative stress may hinder fertilization or implantation even when standard tests appear normal. The discussion on gonadotoxic environmental agents affecting oocyte quality further underscores the importance of environmental and lifestyle exposures in infertility etiology. In the evaluation section, the text offers a pragmatic overview of the diagnostic work-up for both partners, stressing that unexplained infertility is often a diagnosis of exclusion. It encourages critical reappraisal of "normal" findings, advocating for the expanded use of advanced diagnostic assays such as sperm DNA fragmentation, reactive oxygen species testing, uterine receptivity assays, and laparoscopy in selected cases. The fifth section covers treatment options, categorized into expectant, medical, and surgical modalities. Expectant management is critically analysed, with evidence showing it may be suitable for younger couples with shorter infertility durations. Pharmacologic treatments for women include clomiphene citrate, aromatase inhibitors, and gonadotropins; for men, immunological treatments and endocrine modulation are explored. Surgical strategies are also reviewed, particularly when subtle endometriosis or tubal pathology is suspected. The final section explores ART, presenting intrauterine insemination and in vitro fertilization as both diagnostic and therapeutic tools. Success rates, selection criteria, and protocol refinements are discussed, along with the evolving role of advanced sperm selection techniques and embryo diagnostics. The closing chapters provide future perspectives, calling for personalized infertility care that integrates genomic profiling, environmental risk assessment, and more targeted ART interventions.…
