What is an egg cell? Eggs are sex cells, or the female gametes, which carry the genetic material a woman will pass on to her children. At first glance, eggs are large, spherical cells that are produced approximately every 28 days in the female’s ovary. And as you...
The frozen embryo transfer is a fundamental treatment in assisted reproduction and is a common part of many in vitro fertilisation (IVF) processes, both with the patient's own oocytes and with egg donation. Thanks to the vitrification technique (ultra-rapid freezing...
