Pregnant women know how important prenatal care is for the health of both mother and baby. However, it takes a couple very consciously planning for parenthood to prepare for not only childbirth but also conception as the complex process of organic development takes place in the first 12 weeks of pregnancy. This is the time when cell division is fastest, the embryo's weight increases several thousand times within a matter of a few weeks, and it is also the period when the embryo is most vulnerable to external impacts such as elevated body temperature, certain medications, chemical substances, radiation, infections, etc.
When preparing for conception our intent is to minimize all risks that might upset the normal biological course of pregnancy and have a negative impact on the health of the embryo, then the fetus and the neonate.
A scrutiny of the family tree can reveal possible hereditary abnormalities which may require special tests during pregnancy. It is also important to have information on genetic and developmental disorders identified after previous pregnancies as they may necessitate similar tests in order to avoid recurrence.
This is a special gynecological screening. It has a triple aim:
The growing embryo and fetus is exposed to many different (mainly viral) infections. Some of the early viral infections result in lifelong protection for the mother while others may be caught repeatedly. By testing the maternal blood for antibodies we try to assess the risk of infection and if necessary, we administer vaccines for prevention.
Multivitamins containing folic acid can help prevent a large number of developmental abnormalities (primarily open neural tube disorder and fetal acrania).
Proper lifestyle and diet are very important as they enhance the body's resistance.
During the three-month preparatory phase the woman takes her temperature every morning after waking up (using the same thermometer, at the same time, orally, vaginally or possibly rectally). This is called basal body temperature and it helps determine ovulation, the fertile period within the cycle. If basal body temperature stays high after three weeks and the woman misses her next period it is worth trying a home pregnancy test.
After conception an early pregnancy ultrasound screen is recommended to eliminate the possibility of ectopial pregnancy and to establish the gestational age.
PGD is recommended when parents are at risk of transmitting a known genetic condition to their future child that would severely impair the child's prospect or quality of life (=high-risk PGD). PGD is considered in cases of monogenic disorders (autosomal recessive, autosomal dominant or X-linked disorders) or the result of a balanced chromosomal translocation.
