Outcome Measures
Primary Outcomes (1)
Total motile sperm count
The total number of motile sperm cells in the ejaculate. Counted by computer assisted sperm analyzer
Within 1 hour of ejaculate sample procurement
Secondary Outcomes (1)
Donation time
Within 120 minutes of commencement of donation of sample
Study Arms (2)
Virtual Reality
EXPERIMENTALParticipants use Virtual reality headsets as medium of erotica to produce their sperm sample
No Virtual Reality
NO INTERVENTIONParticipants did not use Virtual reality headsets as medium of erotica to produce their sperm sample. They used a computer screen to display erotica.
Interventions
The VR headset was a Pico G2, Pico Interactive, San Fransisco, USA, offering a choice from 60 erotic videos each of 10-30 minutes duration. The men were allowed to watch any and as many of these video clips as they wished. The "No VR" arm, donors used the computer monitor available in the donation rooms.
Eligibility Criteria
You may qualify if:
- Must be able to donate at least 3 samples for each study arm (i.e. minimum 6 samples total).
- Must be an 'accepted' donor at Cryos International i.e. must have a post thaw sperm concentration of ≥5x106 per ml.
You may not qualify if:
- Not an 'accepted' donor at Cryos International
