@nem035 the short answer is that there are few if any good material options. we've been experimenting with new options and have one that we are evaluating rolling out. It's somewhere between 3-7x more expensive than current options and we'd need to pass on the cost.

What else did people think was impossible?

+ 1928: There is no likelihood man can ever tap the power of the atom.

@XSherv sample collection protocol is:
+ ejaculate into the cardboard container
+ stir ejaculate for 5 seconds with metal spoon
+ spoon specimen onto three of the five spots

I reduced microplastics in my blood by 93%.

However, compared to my blood, my ejaculate has 239% the amount of microplastics.

Today, I completed a follow up ejaculate sample collection to see if levels have gone down similar to my blood. Or, if they're more stubbornly stored.

3/ Ice returned and recovery initiated

Following 7 Sessions with icing reapplied

+ Total motile count ↑ 35% (30% recovery)
+ Motility ↑ 30% (23% recovery)
+ Normal morphology unchanged (0% recovery)

Compared to levels following 15 sessions with no icing (recovery calculated

4/ I am measuring again in 2 weeks and report on continued recovery

I expect my motile count and motility to continue recovering over the next 2-4 weeks and back to the previous peak achieved following 27 sessions. This is based on:
+ Relative recovery already achieved in 1

5/ Men out there, definitely ice your balls when you go into sauna

Here is my icing protocol
+ ice the boys during sauna
+ use a non-toxic, reusable ice pack material
+ I wear cotton boxers and shorts
+ place ice packs in-between boxers/shorts
+ keep in place for the entire

0/ The testicles are located “outside” the body in the scrotum specifically to maintain a temperature 2-4 °C below core body temperature, essential for optimal sperm production and storage (in the epididymis) .

Heat is known to multiple steps of spermatogenesis by disrupting the

My results starkly confirm this

1/ Beyond protecting my sperm, icing with sauna boosted all my sperm markers.

27 daily sauna sessions with ice on balls
+ total motile count ↑ 57%
+ concentration ↑ 26%
+ motility ↑ 16%,
+ normal morphology ↑ 15%

This is likely due to

2/ The effect is real, the boys suffered with no ice

15 sauna sessions with full heat on balls
+ total motile count ↓ 54%
+ motility ↓ 57%
+ normal morphology ↓ 55%

Compared to the levels following sauna with ice protection
