Background/Objectives: This study investigates the relationship between cocaine- and amphetamine-regulated transcript (CART) expression, leptin, and hormone profiles—specifically progesterone, testosterone, androstenedione, estradiol, follicle-stimulating hormone (FSH), and human chorionic gonadotropin (hCG)—across four distinct ovulation induction protocols (HMG, HMG/hCG, rFSH, and rFSH/hCG). It also investigates the relationship between follicle-stimulating hormone receptor (FSHR) Ser680Asn polymorphisms, CART expression, and in vitro fertilization (IVF) results, with the goal of better understanding how CART and FSHR polymorphisms affect ovarian response and oocyte quality. Methods: Data were obtained from 94 women who underwent controlled ovarian stimulation (COS) as part of their IVF therapy. Hormone levels, CART expression, and FSHR polymorphisms were measured across all four ovulation induction procedures. Statistical studies were undertaken to investigate the relationships between CART expression, hormone levels, and IVF results. Results: The study found no significant difference in body mass index (BMI) amongst the four stimulation procedures (p-values varied from 0.244 to 0.909). CART expression did not show a significant correlation with hormone levels throughout the whole cohort (progesterone, testosterone, androstenedione, FSH, hCG, and estradiol; p > 0.05). However, CART levels were adversely linked with the number of follicles > 12 mm (r = −0.251, p = 0.018), total oocyte count (r = −0.247, p = 0.019), and oocyte maturity (r = −0.212, p = 0.048). Furthermore, there was a strong negative connection between CART expression and thyroid hormone T3 (r = −0.319, p = 0.048). Among FSHR polymorphisms, the SER/SER genotype was related to greater CART levels (mean 4.198 ± 2.257) than the SER/ASN and ASN/ASN genotypes (p = 0.031). Conclusions: These data indicate that CART expression and FSHR polymorphisms may influence ovarian response and oocyte quality in IVF patients, possibly acting as biomarkers for evaluating ovarian outcomes in various ovulation induction procedures.
