How do they stick a magnet to the head of a sperm cell? and how do they do it for thousands or millions of sperm cells? and how much would it cost for them to do that.

so many questions

Just, don't get them wet now. 😳

I'm a little confused by the terminology in the headline and article, since IVF stands for in-vitro fertilization in this context. I'm pretty sure that literally means the fertilization takes place inside labware. Unless they are trying to say that they are somehow sticking a petri dish up in there, the usage of the term doesn't make any sense.

The article explains that they really mean some sort of remote control artificial insemination of naturally released eggs, which is an interesting idea, but not IVF. They do use the term in-vivo in places, but you can't just swap which word a letter in a standard acronym stands for without explanation and expect to be understood. Most of the places the article says "IVF" they meant to say "controlled fertilization", except the few places they actually were referring to IVF.
