%X <B>UNASSIGNED: </B>Idiopathic hypogonadotropic hypogonadism (IHH) is a prevalent congenital genetic disorder with multiple inheritance patterns. IHH can manifest as normal hypogonadotrophic sexual hypofunction (nIHH) or with an abnormal sense of smell, known as Kallmann. It primarily affects the production and effectiveness of gonadotropin-releasing-hormone (GnRh), leading to reduced follicle-stimulating hormone and luteinizing hormone levels. This results in infertility and underdeveloped secondary sexual characteristics.<BR><B>UNASSIGNED: </B>A 29-year-old female presented with infertility.<BR><B>UNASSIGNED: </B>IHH diagnosis was confirmed through magnetic resonance (MR) scan, endocrine tests, physical examination, and B ultrasonic inspection. Additionally, genetic studies, including chromosome analysis, were conducted for the patient. The results confirmed no genetic abnormalities or concerns.<BR><B>UNASSIGNED: </B>The patient underwent multiple ovulation induction programs.<BR><B>UNASSIGNED: </B>After several ovulation induction cycles, the patient conceived and delivered a live baby.<BR><B>UNASSIGNED: </B>For IHH patients, a tailored human menopausal gonadotropin (HMG) dose is recommended. High-dose HMG can benefit those with poor follicular response. The addition of letrozole (5-7.5mg) may enhance follicular response during stimulation. Our approach, which emphasizes the combined use of high-dose HMG, letrozole, and the adjustment of FSH and LH ratios, offers a unique perspective compared to traditional treatments. If HMG treatment is ineffective, alternative ovulation induction methods, such as r-fsh combined with r-lh or HMG combined with rLH, can be considered. Adjusting the FSH and LH ratio and varying rFSH and rLH additions might help achieve dominant follicles and live birth in resistant cases. This case report underscores the potential benefits of our regimen, suggesting its consideration for future research and clinical applications.
