Autologous Hair Follicle-Derived Secretome and Platelet-Rich Plasma for Premature Ovarian Insufficiency

2026年10月29日 更新者:Dr. Robert F. Casper、Trio Fertility

Does the Secretome From Autologous Hair Follicle-derived Mesenchymal Stem Cells Improve Ovarian Reserve in Women With Premature Ovarian Insufficiency?

This single-arm, open-label pilot study aims to evaluate changes in ovarian function following administration of autologous hair follicle-derived mesenchymal stem cell secretome combined with autologous platelet-rich plasma (PRP) in women with premature ovarian insufficiency (POI).

The study plans to enroll 15 women aged 25-40 years with evidence of diminished ovarian activity, including elevated follicle-stimulating hormone (FSH), low anti-Müllerian hormone (AMH), and reduced antral follicle count (AFC).

The intervention is administered under transvaginal ultrasound guidance into the pelvic cul-de-sac, without direct ovarian injection. Participants undergo serial hormonal and ultrasound assessments to evaluate changes in FSH, AMH, and AFC. Secondary assessments include menstrual function, ovulation, and pregnancy outcomes.

The study is exploratory and is intended to generate preliminary data on ovarian response, feasibility, and safety to inform future controlled investigations.

詳細な説明

Premature ovarian insufficiency (POI) is a condition in which ovarian function declines before the age of 40. Women with POI may experience irregular or absent menstrual periods, reduced estrogen production, and difficulty becoming pregnant. Current treatment options are limited, particularly for women who wish to conceive using their own eggs. New approaches that may support residual ovarian activity are therefore of considerable interest.

This prospective, single-arm, open-label pilot study aims to investigate changes in ovarian function following treatment with autologous hair follicle-derived mesenchymal stem cell secretome combined with autologous platelet-rich plasma (PRP) in women with POI.

The secretome is a preparation containing biologically active substances released by cultured cells, including growth factors and signaling molecules. These substances may influence cellular communication and tissue repair. PRP is prepared from the participant's own blood and contains concentrated platelets that release growth factors. Combining these two preparations is being investigated as a potential approach to supporting ovarian function. However, its effectiveness for POI has not been established.

The study plans to enroll 15 women aged 25-40 years with POI, characterized by elevated follicle-stimulating hormone (FSH), low anti-Müllerian hormone (AMH), and reduced antral follicle count (AFC).

Hair follicles and blood samples are collected from each participant to prepare the autologous secretome and PRP. The combined preparation is administered into the pelvic cul-de-sac under transvaginal ultrasound guidance, without direct injection into the ovaries. Participants undergo follow-up assessments, including blood tests and transvaginal ultrasound examinations, to monitor changes in ovarian function.

The primary outcomes are changes in serum FSH, AMH, and AFC compared with pretreatment measurements. Secondary outcomes include changes in menstrual function, evidence of ovulation, and pregnancy outcomes, including spontaneous pregnancy and pregnancy following fertility treatment.

The study is exploratory and does not include a placebo or untreated comparison group. Its findings will provide preliminary information about changes in ovarian function following treatment and help guide the design of future studies involving larger numbers of participants and appropriate control groups.

実験的:Autologous Hair Follicle Secretome and PRP

Participants with premature ovarian insufficiency will receive autologous hair follicle-derived mesenchymal stem cell secretome combined with autologous platelet-rich plasma (PRP). The combined preparation will be administered into the pelvic cul-de-sac through transvaginal ultrasound-guided injection, without direct ovarian injection. Participants will undergo follow-up hormonal assessments and transvaginal ultrasound examinations to evaluate changes in ovarian function. According to the original protocol, an additional injection may be offered to participants who do not demonstrate an adequate response after approximately three months.

Autologous hair follicle-derived mesenchymal stem cell secretome (aHFS) is prepared from hair follicles collected from each participant. On the day of treatment, approximately 20 mL of peripheral blood is collected to prepare autologous platelet-rich plasma (PRP). The PRP is used to reconstitute the participant's aHFS preparation.

The combined aHFS and PRP preparation is administered through a transvaginal ultrasound-guided injection into the pelvic cul-de-sac (pouch of Douglas), without direct injection into the ovaries.

Participants undergo serial hormonal and ultrasound assessments following treatment. According to the original protocol, a second injection may be offered to participants without an adequate ovarian response after approximately three months.

主要な結果の測定

結果測定
メジャーの説明
時間枠
Change in Serum Follicle-Stimulating Hormone Levels
時間枠:From pretreatment baseline through 3 months after the last injection

Change in serum follicle-stimulating hormone (FSH) concentration, measured in international units per liter (IU/L), from pretreatment baseline to follow-up. FSH is a hormone involved in regulating ovarian function and is typically elevated in women with premature ovarian insufficiency. Blood samples will be collected to assess changes in FSH levels following treatment. A decrease in FSH may indicate a change in ovarian hormonal activity.

From pretreatment baseline through 3 months after the last injection
Change in Serum Anti-Müllerian Hormone Levels
時間枠:From pretreatment baseline through 3 months after the last injection

Change in serum anti-Müllerian hormone (AMH) concentration from pretreatment baseline to follow-up. AMH is produced by cells surrounding developing ovarian follicles and is commonly used as a marker of ovarian reserve. Blood samples will be collected to evaluate changes in AMH following treatment. An increase in AMH may suggest a change in ovarian follicular activity.

From pretreatment baseline through 3 months after the last injection
Change in Antral Follicle Count
時間枠:From pretreatment baseline through 3 months after the last injection

Change in antral follicle count (AFC), measured using transvaginal ultrasound, from pretreatment baseline to follow-up. Antral follicles are small, fluid-filled structures within the ovaries that contain developing eggs. The number of visible antral follicles will be recorded at each assessment. An increase in AFC may indicate an improvement in measurable ovarian follicular activity.

From pretreatment baseline through 3 months after the last injection

メジャーの説明
時間枠
Occurrence of Spontaneous Pregnancy
時間枠:From the initial injection through a year of follow-up

Number and proportion of participants who achieve a spontaneous pregnancy without assisted reproductive treatment following administration of autologous hair follicle-derived secretome combined with platelet-rich plasma. Pregnancy will be assessed using clinical follow-up and available pregnancy testing results.

From the initial injection through a year of follow-up
Occurrence of Pregnancy Following In Vitro Fertilization
時間枠:From the initial injection through a year of follow-up

Number and proportion of participants who achieve pregnancy following in vitro fertilization (IVF) after treatment with autologous hair follicle-derived secretome combined with platelet-rich plasma. Participants demonstrating sufficient ovarian response may be considered for IVF according to the study protocol. Pregnancy outcomes will be assessed through available clinical follow-up records.

IPD プランの説明

Individual participant data (IPD) will not be made publicly available or shared with external researchers due to the small sample size and the sensitive nature of the reproductive health information collected. The study involves a limited number of participants with premature ovarian insufficiency, which may increase the risk of participant re-identification even after removal of direct identifiers. Participant confidentiality will be maintained in accordance with the approved research protocol and institutional review board requirements. Aggregated, de-identified study results may be reported in scientific publications and conference presentations.
