"After 8 weeks my sperm analysis improved significantly. This was the only change I made to my routine."
"My wife and I had been trying for over a year. Doctor mentioned heat as a factor. Three months on these patches and we got pregnant naturally."
Key Benefits
Targets the root cause — raised scrotal temperature is a correctable, often-overlooked risk factor directly linked to poor sperm parameters
Clinically observed outcomes — sperm count improved in 48–66% of men studied; motility and morphology improved by 28–83%
Natural L-menthol hydrogel formula — 5.5" x 3.5" soft gel patch, individually wrapped, trimmable to size, no refrigeration required
Effortless nightly routine — apply before bed, cool for 6–8 hours, wake up having done something about it
The Problem
Heat reduces sperm quality
Laptops, sedentary work, and tight clothing raise scrotal temperatures — directly damaging spermatogenesis
The Evidence
48–66% improved sperm count
Across reviewed clinical studies, scrotal cooling consistently improved sperm count, motility and morphology
The Solution
Nightly 90-day cooling protocol
Consistent nocturnal cooling with IcySack addresses the heat factor you can actually control
The most overlooked cause of male infertility is heat — and it's fixable
Optimal spermatogenesis requires the testes to be maintained 1–2°C below core body temperature. Modern habits — sitting for hours, using laptops, wearing tight clothing — consistently push scrotal temperature above this threshold.
A review of the clinical literature found sperm count improved in 48–66% of infertile men with scrotal cooling. Six of eight studies showed improvements in sperm motility, morphology, or both — ranging from 28% to 83%. Early improvements were noted from two weeks onward, with statistically significant changes from eight weeks.
The SCOP trial — a randomized controlled trial at the University of Nottingham — was specifically designed to test the FertilMate scrotal cooling patch on men with oligoasthenospermia over a 90-day protocol. It represents the most rigorous study of this product category to date.

Apply before bed
Peel and apply the patch to the scrotum. Trim to size if needed. No refrigeration required.
Cool through the night
The 0.5% L-menthol hydrogel delivers a steady, comfortable cooling effect for 6–8 hours while you sleep.
Repeat for 90 days
The SCOP trial protocol uses 90 consecutive days of nightly application. Significant improvements typically observed from week 8.
Support sperm health
Lower scrotal temperature supports healthy spermatogenesis — improving count, motility and morphology.
How long before I see results?
Some improvements may be seen as early as two weeks. Statistically significant changes in sperm count were typically noted from eight weeks onward in clinical studies. The full SCOP trial protocol runs 90 consecutive days.
How many patches come in each pack?
Each pack contains 20 individually wrapped patches. The 1-pack covers 20 nights, the 2-pack 40 nights, and the 4-pack 80 nights. For a full 90-day protocol, the 4-pack plus a 1-pack top-up covers you completely — our subscription delivers automatically so you never run out.
Is the patch safe to use?
The patch uses natural L-menthol in a soft hydrogel formula (5.5" x 3.5"). Do not use if you have a known menthol allergy, have had genital surgery or vasectomy, or have a chronic medical condition. Consult your physician if unsure.
Does it need refrigeration?
No. The cooling effect is delivered entirely by the L-menthol formula — no pre-chilling needed. Each patch is individually wrapped and can be stored at room temperature.
Is this only for men with diagnosed infertility?
While clinical research focused on men with oligoasthenospermia, the patch may benefit any man looking to optimize sperm health — including those actively trying to conceive who want to eliminate heat as a risk factor.
Is packaging discreet?
Yes. All orders ship in plain, unmarked packaging with no indication of contents on the outside of the box.
