Background: Although current penile enlargement techniques can improve appearance, it remains unclear whether these procedures increase sexual function. We aimed to systematically compare the surgical outcomes, with a particular focus on sexual function, in patients and their partners following silicone pearls implantation and fat grafting for penis enlargement.
Methods: A single-site, retrospective study reviewed patients who underwent silicone pearls implantation or fat grafting for penis enlargement. In the operation, silicone pears were connected to form a ring-shaped implant, which was then implanted under the dartos fascia. For patients underwent fat grafting, a total of 40-55 ml of fat was injected for penis enlargement. Preoperative and 6-month postoperative data of patients and their partners were collected. The penis diameter, penis appearance score (PAS) and treatment satisfaction scale (TSS) were evaluated.
Results: Both pearls implantation (n = 28) and fat grafting (n = 27) led to an increase in penis diameter. The TSS scores of patients who underwent pearls implantation increased by 11.96%, and the partners' scores increased by 9.17%. Specifically, Confidence, Pleasure from Sexual Activity, and Satisfaction with Orgasm scores of partners showed significant improvements. Partners' Satisfaction with Orgasm increased most. The total TSS scores of patients with fat grafting increased by 16.7%; meanwhile, scores of their partners had not obvious improvement.
Conclusion: Silicone pearls implantation was found to effectively improve the sexual function of men and the sexual satisfaction of their partners compared to fat grafting. Therefore, pearls implantation is possible to enhanced sexual experiences both for man and their partners.
