IVF is the most commonly used and the most effective treatment for infertility. In-Vitro Fertilisation (IVF) is conception outside of the human body. Sperm is collected from the man and is placed in a special incubator. The woman undergoes ovulation induction (hormonal stimulation of her ovaries) and eggs are collected. This is done through the vagina under ultrasound control. The collected eggs are mixed with the sperm and they are placed in a special incubator. The fertilised eggs develop into embryos, which are then implanted into the woman’s uterus through a thin tube inserted through the cervix, again under ultrasound guidance. IVF success rates vary, depending on factors such as your age and the cause of your infertility.
