About

Five healthy participants with normal sperm counts and motility will ingest increasing doses of celastrol over a period of several days. After each dose ingestion the participants will provide an ejaculate the next day for sperm analysis. The objective is to see if increasing ingestion levels of celastrol will affect the sperm counts and motility of the participants.

Full description

Experimental Design This will be an escalating dose study to determine the effects of different enteral dosages on sperm motility. Five healthy participants, of any ethnicity, between 18 and 40 years of age will be candidates for the study.

Baseline Days 1- 3 The five participants arrive at the clinic on Baseline Day 1, and will sign Consent Forms after being qualified by the inclusion and exclusion criteria. The participants will provide the first of three "qualifying" sperm samples (a sperm count of ~20 million sperm per milliliter of ejaculate, and sperm motility of ≥ 40% one hour after ejaculate). If the participants initial sample is "normal," then the participants will return to the clinic after three or more days to provide a second sperm sample. Again, if this second sample also meets the sperm count of ~20 million sperm per milliliter of ejaculate, and sperm motility of ≥ 40% one hour after ejaculate, then the participants will return to the clinic for a third time and provide a third and final "qualifying" sperm sample. The average of the "qualifying" sperm counts obtained during the three-day "qualifying period" will be used for the Baseline data, and will be used to compare sperm counts of the participants who ingest Celastrol during the remaining Experimental Days.

Experimental Day 1 All participants that provide three sperm samples that meet the "qualifying" criteria, will then return to the clinic after three or more days and have the participant medical histories taken; receive a physical examination; and have a blood sample taken. The five participants will be instructed to ingest the first dose of Celastrol (6.7 mg). Three hours after ingestion of this dose, the participants will provide a sperm sample.

Experimental Day 2 The participants will return to the clinic three days (or more) after Experimental Day 1. The five participants will be instructed to ingest the second dose of Celastrol (20.1 mg). Three hours after ingestion of this dose, the participants will provide another sperm sample.

Experimental Day 3 The participants will return to the clinic three days (or more) after Experimental Day 2. The five participants will be instructed to ingest the third dose of Celastrol (40.2 mg). Three hours after ingestion of this dose, the participants will provide another sperm sample.

Experimental Day 4 The participants will return to the clinic three days (or more) after Experimental Day 3. The five participants will be instructed to ingest the fourth dose of Celastrol (67.0 mg). Three hours after ingestion of this dose, the participants will provide another sperm sample.

The doses will be:

6.7 mg Commercial Dosage 20.1 mg 3x the Commercial Dose 40.2 mg 6x the Commercial Dose 67.0 mg 10x the Commercial Dose

Inclusion criteria

Individuals who are between 18 and 40 years of age and who are found to be healthy without any underlying medical conditions that could affect sperm motility, and are not taking any daily medications. This does not exclude patients who take drugs prn.

Exclusion criteria

Individuals who have been involved in any other clinical trial during the last 90 days.
