I am preparing for in vitro fertilization (IVF) embryo transfer. Afterwards, I plan to travel with my family during the holidays; will this affect the chances of pregnancy? (Ha Thu, Hanoi).

I underwent in vitro fertilization and produced 5 embryos, but 4 failed to develop. The one day 5 embryo transferred did not result in pregnancy. Is there a way to improve embryo quality? (Linh, age 33)

Ms. Nhai, 32, successfully conceived after 8 in vitro fertilization embryo transfers over 8 years due to uterine adhesions.

My husband and I received embryo biopsy results showing aneuploid abnormalities in multiple chromosomes (3, 4, 9) and a 30% mosaicism rate. Should such an embryo be transferred to the uterus? (Linh, Lam Dong)
