- The Male-Factor Pak allows patients to collect a specimen during intercourse,
- Providing a natural alternative to yesterday's tradition: a cup.
- Gives medical specialists the opportunity to work with more representative samples
- Studies show that semen samples obtained through intercourse are more viable than those obtained through masturbation.
- Improved specimen viability and increased patient acceptance when masturbation is objectionable, are the benefits that medical professionals have been waiting for.
- Non-Spermicidal. Biologically inert polyurethane condom maintains sperm viability, motility and velocity. No mold; releases or powders used in condom manufacture
- Psychologically Acceptable. Allows sample collection at home or other private settings and eliminates patient stress traditionally caused by religious, cultural or emotional objections to manual or coitus interruptus ("pull out").
- Comfortable and Gentle. Ultra-thin polyurethane facilitates sensitivity, satisfaction and high sexual stimulation.
- Easy to Use. Patient simply cleans genitals prior to use, removes condom when erection has ceased after ejaculation, and closes condom with a provided twist-tie.
- Easy to Transport. Patient seals condom in compact pouch with patient I.D. label, and transports to physician or laboratory, carrying it close to body to maintain specimen temperature.
- Sterile. Individually sealed and packaged
- Less Costly. The Male-Factor Pak is priced lower than its leading competition.
- The inability to produce semen specimens at the time of seminal evaluation may reflect difficulties with sexual drive and deficient seminal parameters.
