The Male-Factor Pak (MFP) is a specimen collection condom which allows patients to obtain high-quality semen samples for fertility and sterility testing and for use in other assisted reproductive technologies. By allowing patients to collect a specimen during intercourse, it provides a more natural alternative to yesterday's tradition: masturbation. It also gives medical specialists the opportunity to work and evaluate a more representative sample than ever before.
Pre-Seed is the first lubricant specifically designed for use at intercourse that has non spermicidal qualities. It is ‘sperm-friendly’ as it matches the qualities of the fertile cervical mucus, so it provides a helpful environment to facilitate conception. It is also an excellent lubricant for the male to use under the MFP since the MFP is a dry, non-lubricated condom. And because it is non-spermicidal, it DOES NOT negatively impact the specimen. In fact, it makes for a better quality sample. It can enhance better possibilities for higher sexual stimulation with subsequent superior ejaculate production. The superiority will be reflected in higher ejaculate volume, higher sperm number and better quality sperm.
The Male Factor Pak (MFP) can be used for fertility testing and other treatments. This more natural method of sperm collection is recommended for couples who are experiencing male factor fertility issues or other while undergoing IUI or IVF.
It also gives medical specialists the opportunity to work with more representative samples produced at intercourse than ever before. Studies show that semen samples obtained through intercourse are superior producing more viable sperm than those obtained through masturbation.
Improved specimen viability and increased patient acceptance when masturbation is objectionable, are additional 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 masturbation 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.
