Two follicles at ovulation what are the chances of having twins?

If two mature eggs are released during ovulation and are fertilized by two separate sperm cells, it can result in fraternal (dizygotic) twins. Fraternal twins occur when two different sperm cells fertilize two separate eggs. Since they are formed from different eggs and sperm, fraternal twins can be of the same or different sexes, just like non-twin siblings.

The chance of having fraternal twins is affected by several factors, including genetics and reproductive treatments. Some women are more likely to release multiple eggs during ovulation due to genetic factors or conditions like polycystic ovary syndrome (PCOS). Additionally, certain fertility treatments, such as ovulation induction medications or in vitro fertilization (IVF), can increase the chances of releasing multiple eggs and thus the likelihood of fraternal twins.

It's important to note that having two follicles at ovulation does not guarantee that fraternal twins will occur. The chances of achieving pregnancy and the occurrence of twins can vary based on individual circumstances and the success of fertilization and implantation.
