Believe it or not, the season (humidity) you get your implant affects infection rate
The purpose of this study is to investigate the relationship between inflatable penile prosthesis (IPP) infection, time of year, climate, temperature and humidity. This is a retrospective IRB-approved analysis of 211 patients at 25 institutions who underwent salvage procedure or device explant between 2001 and 2016. Patient data were compiled after an extensive review of all aspects of their electronic medical records. Climate data were compiled from monthly norms based on location, as well as specific data regarding temperature, dew point, and humidity from dates of surgery. Rigorous statistical analysis was performed. We found that penile prosthesis infections occurred more commonly in June (n = 24) and less frequently during the winter months (n = 39), with the lowest number occurring in March (n = 11). One-hundred thirty-nine infections occurred at average daily temperatures greater than 55 °F, compared to 72 infections at less than 55 °F. The incidence rate ratio for this trend was 1.93, with a p-value of <0.001. Humidity results were similar, and fungal infections correlate with daily humidity. Infected implants performed in the fall and summer were over 3 and 2.3 times, respectively, more likely to grow Gram-positive bacteria compared to implants performed in spring (p = 0.004; p = 0.039). This was consistent across geographic location, including in the Southern hemisphere. We found trends between climate factors and IPP infection like those seen and proven in other surgical literature. To our knowledge these data represent the first exploration of the relationship between temperature and infection in prosthetic urology.

Well, I guess I'm happy that I received my implant during February.

It is certainly the case that surgeries carried out late on a Friday have worse outcomes on average.
I was relieved when I found out I was in on a Monday.

Not sure if I’m glad or not that I read this after my Friday surgery in August lol.

It's just an average, the statistical significance was inferred from a huge sample size, which increases the chance of a significant result. Increase the sample size enough and you will eventually find a significant result with any difference, that doesn't mean it is meaningfully significant. Statistics are often arbitrary rather than intrinsically true. We design our tests by rule of thumb, because doing it this way is, almost always, useful to us. This makes stats vulnerable to abuse. It wasn't intentionally abused in this case, but it gave the impression that day and time is more important than it is.
It is the case that outcomes were worse on Fridays, but I wouldn't worry about it as I did. The results speak to the population level, as an individual other factors are much more important.
You have to take into account that surgeons do not operate everyday, for example. At least in the UK they don't. It's normally 2 or (rarely) 3 days a week. At least for urologists, at least on the NHS.
Perhaps they avoid operating 5 days a week due to fatigue? I don't know.
I brought it up more as a curiosity than something to consider pragmatically.
Even though I did worried about it, because I'm human, and humans are not always logical when emotional.
