What might be the cause?

Depopulation Agenda is real, most of these chain stores are using Monosodium Glutamate, and all kinds of chemicals-infused crops to cook for the masses. Sexual perversion, lifestyle, number of abortions, and poorly treated infections are factors, too. It's a sad reality.

Let me just put this here....

Where is the data to back this up? Just turn on ring light and yan without statistics.

Untreated STIs, too much alcohol, smoking, and drug lifestyle and finally plenty people dey push marriage/pregnancy go far because of hustle. AGE dey reduce fertility gradually, especially after 30.

It's in our food and drugs. One of the goals of WHO is to reduce population through several means, and it's working out well. Most of the "English" drugs we take, especially antibiotics & reproductive inhibitors like Postinor 2 & abortion pills, affect libido & fertility.

Honestly, people are so scared of the stigmatization that comes with it when they voice out. Many people need help.

Food and diet plays little role, main causes are hormonal inbalance, infection (chlamydia, gonorrhoea etc) can mess your falopain tubes or testes up if left untreated for a prolonged period, endometriosis is also a common factor for women. It will only get worse unfortunately

It’s as a result of of stress anxiety and responsibility, people take this world and life too seriously that they can’t even have a quality time for themselves to rest

Bill Gates’ ‘free’ vaccine (there’s always a reason it’s free). Time will tell. In the next couple of decades, the truth will be clearer. It’s not even surprising anymore to see young African girls growing beards, right? History has a way of revealing what was hidden in plain sight.
