Hi, Tetraploid state is a condition where there are four times the haploid number of chromosomes; in other words, there are two sets of 23 pairs of chromosomes observed. This occurs in 1-5 percent of pregnancies and is most often culminated in an early trimester abortion. Even if the baby survives, the expectancy of life is very short. In the current scenario, you need to take genetic counselling as you had two abortions, increasing the possible risk of another abnormal pregnancy. If it is deemed that you or your partner carry an abnormal karyotype, sperm or oocyte donation can be thought of as a possible treatment option. Hope you find this information useful. Take care.
