Are twins more common after vasectomy reversal?

Vasectomy reversal has no effect on twin rates, as this simply restores the flow of sperm to the semen (2). Hormonal stimulation used in fertility treatments and the transferring of multiple embryos during in-vitro fertilization (IVF) increases the incidence and probability of birthing twins, triplets or more (3).

Can a man cause identical twins?

While men can carry the gene and pass it on to their daughters, a family history of twins doesn’t make them any more likely to have twins themselves. 3 But, if a father passes on the “twin gene” to his daughter, then she may have a higher chance than normal of having fraternal twins.

How did I get pregnant with identical twins?

When do eggs split for twins?

Zygotic splitting occurs between days two and six when the zygote divides, usually into two, and each zygote then goes on to develop into an embryo, leading to identical twins (or triplets if it divides into three). These are known as “monozygotic” twins (or triplets).

Is there a special way to get pregnant with twins?
