Background: Infertility affects a large population of reproductive age group couples. The diagnosis and treatment of infertility stands out as one of the most rapidly evolving area in the field of medical science. The incidence of primary infertility in Indian population ranges from 3.9% to 16.8%. Since hysteroscopy offers a direct view of the uterine chamber to identify any potential abnormalities, it has become an essential method for detecting infertility. The objective of this research is to evaluate the use of diagnostic hysterolaparoscopy (DHL) for evaluation of infertility. Materials and Methods: This study was a retrospective observational study conducted at Rama Medical College, Hospital & Research Centre a tertiary care hospital of North India. Total 185 female patients aged 25-40 years with normal hormonal profile who had a previous history of infertility were included. Cases with male factor infertility were excluded from the study. The study was conducted throughout the year in 2023. Characteristics variables on the social and demographic of individuals and their medical history pertaining to infertility were collected in Microsoft Excel. The significance threshold was established at 5% with a significance level of α = 0.05. Results: Out of the 300 infertility cases, 191 (63.7%) had primary infertility, whereas 109 (36.3%) had secondary infertility. Diagnostic laparoscopy detected abnormalities in 68 (35.6%) of the individuals with primary infertility and 52 (47.7%) of the cases with secondary infertility. Significant hysteroscopy findings were noted in 43 (22.5%) cases of primary infertility. Diagnostic hysterolaparoscopy detected abnormalities in 29 (26.6%) cases of secondary infertility. Together, diagnostic hysterolaparoscopy detected abnormalities in 24% cases of the infertile patients in both groups. Abnormalities identified during hysteroscopy were 29 (15.2%) of the individuals with primary infertility and in 13 (6.8%) of the cases with secondary infertility. The prevalent abnormalities detected during hysteroscopy were endrometriosis, fibroids, adnexal adhesion and uterine septa. The incidence of tubal obstructions was higher in the primary infertility group compared to the secondary infertility group. Conclusions: Diagnostic Hysterolaparoscopy (DHL) is an effective diagnostic method for evaluation of different significant and correctable tubo-peritoneal and intrauterine pathophysiological conditions like adnexal adhesions, peritoneal endometriosis, and subseptate uterus, which are usually missed by other imaging technologies.
