Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What is the capacity of participants accepted into this research endeavor?

"Affirmative. The information available on clinicaltrials.gov attests that this medical experiment, first published on July 1st 2018, is presently recruiting participants. 24 individuals need to be enrolled from a single research centre."

Answered by AI

Does the FDA recognize Testosterone and LPWS as safe treatments?

"Taking into consideration the stage of development for Testosterone and LPWS, our team at Power rated their safety as a 2. This is indicative that while there are certain datapoints surrounding safety, efficacy has yet to be demonstrated."

Answered by AI

Who is deemed an ideal candidate for this trial?

"This trial seeks individuals who have experienced spinal cord injuries and are of legal age, between 18-70 years old. The study is looking to enrol 24 patients in total."

Answered by AI

Are there any vacancies for participants in this trial?

"As evidenced on clinicaltrials.gov, the study is actively recruiting participants since it was first posted on July 1st 2018 and recently updated April 5th 2022."

Answered by AI

Could you please provide details about prior investigations related to Testosterone and LPWS?

"Currently, 29 trials examining the efficacy of Testosterone and LPWS are running. Of these experiments, 5 have graduated to Phase 3 testing. Although many of the studies connected to this treatment are based in Houston, Texas, there is a total of 124 research centres conducting such tests around the nation."

Answered by AI

What are the typical indications for Testosterone and LPWS treatment?

"Testosterone and LPWS have demonstrated efficacy in treating hypogonadotropic hypogonadism, as well as post-menopausal conditions that occur within the span of 1 to 5 years. These treatments are also commonly prescribed for orchidectomy and orchitis patients."

Answered by AI

Does this research endeavor open to younger participants under 25 years old?

"This study specifies that applicants aged 18 to 70 are eligible. Additionally, there exist 37 trials for individuals under the age of majority and 326 studies dedicated to those over pensionable age."
