Background: One of the most common chronic health conditions affecting young adults is infertility, which is defined as a year of unsuccessful attempts at conception. The diagnosis has made progress of reproductive problems over the past ten years. Objective: The standard testing used to identify infertility is included in this review. We also go into other tests, such as ovarian reserve evaluation, and the prospective application of laparoscopy in the evaluation of infertility that cannot be explained. Methods: PubMed, Google Scholar, and Science Direct were some of the places we explored for information about Infertility, Standard tests and New tests for Diagnosis. Between July 1992 and January 2022, however, only the latest or most comprehensive study was considered. The authors also assessed the usefulness of references taken from similar books. We haven't paid attention to non-English documents because we don't have the time or money to translate them. Unpublished articles, oral presentations, conference abstracts, and doctoral dissertations were all widely acknowledged to not constitute valid scientific research. Conclusion: A thorough but time-efficient investigation of the infertile couple is required prior to a diagnosis of unexplained infertility. Couples should undergo a semen analysis, ovulation testing, assessment of ovarian reserve, and imaging to assess for tubal and uterine factors before a diagnosis of unexplained infertility is made. This workup can be completed within 1 menstrual cycle.
