In 1984 the first baby was born after IVF in Norway. Presently, about 1 percent of all babies born in Norway are IVF-babies. Though the number of replaced embryos usually is reduced to two, the success rate is unchanged, but decreasing with increasing age of the woman, especially after the age of 35. The proportion of twins is so high that one should consider only to replace one embryo in selected cases. The mortality is higher than expected for singletons, but seems to be decreasing.

Fertilization

During fertilization, an egg and sperm cell fuse to create a new diploid structure. In humans, the process occurs once the egg has been released from the ovary, and travels into the fallopian tubes. The process requires several key steps: 1) sperm present in the genital tract must locate the egg; 2) once there, sperm need to release enzymes to help them burrow through the protective zona pellucida of the egg; and 3) the membranes of a single sperm cell and egg must fuse, with the sperm...

In Vitro Fertilization

In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...
