I have gone through your query & understand your concern.
47 XX +16 means that trisomy 16, i.e. there is an extra copy of chromosome 16. Normally, all human beings have 23 pairs of chromosomes, making a total of 46. Trisomy 16 is unfortunately associated with recurrent 1st trimester spontaneous abortions. I advice you to find a good gynaecologist for genetic counselling.
Thank you for contacting healthcare magic.
