TREATMENT

Nowadays, people in Thai society tend to get married at older ages. According to the figure in picture 1, we can see that age plays as an important role in the quality of eggs. The best time for reproductive systems is between 25 – 29 years old and then will continue to decrease especially when women are more than 35 years old. This is why there is a recommendation for women to do egg freezing before turning 35 years old in order to stop egg ageing. 

Picture 1 demonstrates the relationship between ages and reproductive percentile.

Additionally, the eggs in women who are more than 35 years old tend to have embryos with abnormal chromosomes when fertilize with sperm.  This fact is shown in picture 2.

Picture 2 demonstrates the relationship between age of women and percentile 

of having Down syndrome babies.

Due to egg production stops since being in mother’s womb and have the most amount during 7 months of pregnancy. Then the amount will gradually decrease that is why women should consider egg freezing when they are still young according to picture 3.

The process of egg freezing begins by stimulating ovaries in order to produce multiple eggs as same as doing IVF / ICSI procedure.  It is to make sure that we have enough eggs. After eggs are in an appropriated size, they will be retrieved and stored separately from sperm by the method of eggs freezing which is the same as embryo. The only differences are the chemicals being used. However, after being frozen, the endurance of eggs is less then embryos.  After eggs are dissolved to prepare for fertility, the remaining eggs are only 80% from overall.

Egg Freezing Indications

1. Egg freezing is done to fertilize with sperm that belongs to legal husband in the future.

2. Egg freezing is done after being diagnosed with a certain cancer which the plan of treatment: for example, chemotherapy can affect eggs production.  In addition, treatments for other diseases can cause lower quality in egg production as well.
