Introducing the Male Factor Pak - a game changer for couples trying to conceive. Our non-spermicidal condom has been specially designed to enhance sexual stimulation, resulting in higher ejaculate production, including a higher volume of sperm with better quality. This can make a crucial difference for couples who have been struggling with conception. Get the Male Factor Pak today and take the first step towards a happier family!


The Male Factor Pak (MFP) is a specimen collection condom that 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.

We suggest a fertility friendly 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, which provides a helpful environment to facilitate conception

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.
