Induction stove vs. "normal" cooktop

In the new house, we then chose a halogen/glass ceramic cooktop. We also hadn’t quite finished with our family planning yet ;)

Did you conceive children in the old house? Basically, I would first classify the clinic's statement as selection bias. Among the group of infertile men, you will also find many who have an induction cooktop at home. After all, these have now become quasi-standard in mid-priced kitchens. Conversely, you will also find many fertile men with induction cooktops. Basically, according to the current state of research, there is no reliable connection between everyday EM fields and discomfort or even damage. Since this has been looked for for quite a long time, I also assume that probably nothing more will be found. What is known and very well documented, however, is the nocebo effect. Be it in drug studies with massive side effects in the control group, drunkenness symptoms with non-alcoholic beer (no joke!), or WLAN, mobile phone, and microwaves. Therefore, two possibilities remain: 1. Acceptance of harmlessness and the search for another cause, e.g. subtle noises 2. Removal of all supposedly dangerous devices. Switching to a gas stove (but beware: gas leaks are really dangerous), corded phone, etc.

I also think that the frequencies should be distinguished here. Personally, I prefer to expose myself to a 1kW 50Hz field rather than a 1kW field in the GHz range :cool:

At GHz, thermal power densities are of greater interest and, in the long term, excessive DNA damage (cancer) caused by them.

With low-frequency radiation such as in switching power supplies or mains voltage, the striking and still unknown effect for many is the impact on cell regulation - i recommend in this context the following work on the connection with calcium channels, which are found in every cell. They mediate the electromechanical coupling in muscle contraction, lead to the synthesis and secretion of neurotransmitters and hormones, regulate gene expression, and control enzyme activities. However, these are modulated by low-frequency EMC interferences and also affect, among other things, NO signaling (Nobel Prize 1998 among others Furchgott)!

For example:
M.Pall "Electromagnetic fields act via activation of voltage-gated calcium channels to produce beneficial or adverse effects" (doi: 10.1111/jcmm.12088)

The direct targets of electromagnetic fields (EMF) in the extremely low frequency and microwave range for generating non-thermal effects are not clearly defined. However, the studies discussed here in the literature provide substantial support for such direct targets. Twenty-three studies have shown that voltage-gated calcium channels (VGCCs) mediate these and other EMF effects, so that L-type or other VGCC blockers block or strongly attenuate various EMF effects. Furthermore, the voltage-dependent properties of these channels can provide biophysically plausible mechanisms for biological effects of EMF. Downstream reactions to such EMF exposures may be mediated through Ca2+/calmodulin stimulation of nitric oxide synthesis. Physiological/therapeutic responses are possibly largely the result of stimulation of the nitric oxide-cGMP-protein kinase G pathway. A well-studied example of such an apparent therapeutic response, EMF stimulation of bone growth, seems to operate via this pathway. However, pathophysiological responses to EMF may be the result of the nitric oxide-peroxynitrite-oxidative stress pathway. One well-documented example, the induction of single-strand DNA breaks in cells by EMF, measured by alkaline comet assays, is discussed here. It is known that such single-strand breaks are caused by the action of this pathway. Data regarding the mechanism of EMF induction of such breaks are limited; available data support this proposed mechanism. Other Ca2+-mediated regulatory changes, independent of nitric oxide, might also play a role. This article presents a number of VGCCs whose stimulation produces non-thermal EMF responses in humans/higher animals, with downstream effects including Ca2+/calmodulin-dependent increases in nitric oxide that could explain therapeutic and pathophysiological effects.

Or one may also look in Nature, doi:10.1038/srep21774

That’s exactly what I wanted to write. High-frequency fields are significantly more energetic and also heat tissue. Hence perhaps the doctor’s question regarding the gonads ;).

I recommend in this context the following work on the relationship with calcium channels, which are found in every cell.

N-/PQ type or both? Just kidding. I can imagine that, but the layperson won’t understand it anyway.

N-/PQ-type or both? Just kidding. I can imagine, but laypeople won't understand it anyway.

True... Can someone explain that briefly and clearly for laypeople?

Can't we just conclude that induction is simply not for the OP, instead of giving some kind of lecture? I'm grinning here too, but what is that supposed to achieve?

As far as I know, there is no induction cooktop that advertises reduced magnetic radiation. There are limit values for this type of device that are industry standard.
