  > Were you also brought up with the myth of that one super sperm that ‘fertilizes’ an egg? > Then I have ‘bad news’. The story is completely outdated. A few dozen, sometimes hundreds of sperm cells enter into a biological conversation with an egg. It is about exchanging with each other, in order to eventually merge. Penetration is not the word for what is happening here. Call it a cellular mating dance. This is clearly nonsense as IVF works fine.

    Poor argument I think. INV involves tens of thousand of sperm. However, I'm saying I agree with the grandparent. https://en.wikipedia.org/wiki/In_vitro_fertilisation#Co-incubation https://en.wikipedia.org/wiki/In_vitro_fertilisation#Co-incu... The sperm and the egg are incubated together at a ratio of about 75,000:1 in a culture media in order for the actual fertilization to take place.

      > In certain situations, such as low sperm count or motility, a single sperm may be injected directly into the egg using intracytoplasmic sperm injection (ICSI).

    How much is the efficiency or success rate of ivf embryos?

    So, what you're saying is the equivalent of "plants don't grow in nature, they grow in greenhouses"? I don't see how what you're stating contradicts the author.
