Overview
Female Sexual Dysfunction (FSD) represents a critical public health challenge, significantly impacting women's physical, psychological, and social well-being. Despite its prevalence, cultural barriers in Vietnam and other Asian countries often limit awareness and research on FSD. Existing treatments, such as hormone therapy, carry risks like cardiovascular complications and cancer, emphasizing the need for innovative interventions. This study investigates FSD-related factors and evaluates the efficacy of autologous adipose-derived mesenchymal stem cell (MSC) therapy as a novel approach.
In this phase 2 clinical trial, MSCs are intravenously administered at a dose of 10^6 cells/kg. These autologous cells, which are non-immunogenic, survive for approximately 8 weeks and release growth factors and cytokines to enhance vascular supply, reduce harmful inflammation, and counteract cellular aging. The study enrolls 50 female participants randomized into two groups: Group A receives MSC infusions at months 0 and 3, while Group B acts as a control for 6 months.
Outcomes are assessed through clinical evaluations, blood tests for hormonal levels, molecular analyses, and internationally validated quality-of-life and sexual function scales. Evaluations are conducted at baseline, 3, and 6 months post-infusion. This research seeks to provide robust evidence for the safety and efficacy of MSC therapy, offering a promising alternative to conventional treatments while addressing a critical gap in women's health.
Description
Female Sexual Dysfunction (FSD) is a significant public health concern. FSD can lead to various health issues and increase the risk of developing other conditions such as osteoporosis, cardiovascular diseases, and cancer. Although hormone therapy is commonly used to treat FSD, its long-term use may have adverse effects on cardiovascular health and raise the risk of cancer. Therefore, exploring new, safe, and effective treatment methods is essential. In 2015, the FDA approved the use of flibanserin (Addyi® Sprout Pharmaceuticals, USA) for premenopausal women with reduced sexual desire. However, this therapy remains controversial due to its potential side effects and limited efficacy. Current treatments for Female Sexual Dysfunction (FSD) mainly involve hormone replacement therapy, gonadotropin therapy, dietary supplements, or lifestyle modifications. While hormone therapy is commonly used to address hormonal decline in women, long-term use may lead to cardiovascular issues or cancer. Therefore, exploring psychological therapies and researching new potential treatments to meet patients' needs is essential.
Recent studies suggest that mesenchymal stem cells (MSCs) offer a safe approach to restoring hormone deficiencies. Clinical trials have investigated the use of MSC transplants to treat conditions like premature ovarian failure and ovarian cancer. Numerous trials have employed MSCs derived from bone marrow, umbilical cords, adipose tissue, or menstrual blood to address ovarian and uterine dysfunctions. Edessy et al. reported using autologous stem cells to treat 10 participants with premature ovarian failure. Following transplantation, two participants resumed menstruation within three months, one of whom became pregnant after 11 months and delivered a healthy full-term baby. Hormonal tests in the pregnant case revealed restored levels of FSH, LH, E2, and AMH to normal ranges. Although these studies are limited by small sample sizes and the lack of control groups, they highlight the potential of MSC transplantation as a treatment for FSD.
A study by Mashayekhi et al. demonstrated the safety of autologous adipose-derived mesenchymal stem cell (MSC) therapy for premature ovarian failure, with no adverse effects reported among nine participants receiving different cell doses. Menstruation resumed in two participants in both the high-dose (15x10^6 cells/kg) and lower-dose (5x10^6 and 10x10^6 cells/kg) groups, while serum FSH levels improved in four participants. Despite small sample size and lack of a control group, the study supports the safety of MSC infusion into the ovaries. Another ongoing trial (NCT01853501) aims to further investigate MSC therapy for ovarian failure, though results are pending. In Vietnam, the Vinmec Institute of Stem Cell and Gene Technology conducted a study on Female Sexual Dysfunction (FSD), using intravenous MSC infusions for 16 women. The trial reported no adverse effects, with participants reporting improved satisfaction with sexual health, though hormone levels (AMH, FSH, and E2) showed no significant changes.
This study aims to address the need for a novel and more effective approach to treating hormonal decline in women, not only improving sexual function but also enhancing their quality of life. Based on this rationale, we have decided to conduct the study titled "Investigating the efficacy of autologous, adipose-derived mesenchymal stem cell therapy for the treatment of sexual function impairment in women aged 40-50," with the following objective: Evaluate the improvement in sexual function among women aged 40-50 years who received autologous adipose-derived mesenchymal stem cell (MSC) therapy.
