Freezing your embryos

The embryos to be frozen are placed in a state of suspense in liquid nitrogen at a cool -196 degrees Centigrade. There are two ways of freezing embryos:

i 'Slow freeze' method: Using this conventional method, the temperature of the embryos is gradually decreased down to the required level. A special chemical is used to protect the cells in the embryo so that damaging ice crystals don't form inside them.

i Vitrification: Using this newer and faster technique, the embryos are placed in a droplet of a particular solution and then immediately placed in a special container that's cooled by liquid nitrogen. The droplet with the embryo instantly transforms into a glass-like bead. Because the freezing process is so fast, ice crystals don't have enough time to form.

Clinics charge for embryo storage, so if you know you're not going to use embryos that you have stored, you need to notify the clinic about what you want to do with them. Deciding what to do with frozen embryos that you don't plan to use can be very difficult, and I discuss your options in Chapter 15.

Pregnancy Diet Plan

The first trimester is very important for the mother and the baby. For most women it is common to find out about their pregnancy after they have missed their menstrual cycle. Since, not all women note their menstrual cycle and dates of intercourse, it may cause slight confusion about the exact date of conception. That is why most women find out that they are pregnant only after one month of pregnancy.
