When does the production of hcg begin After fertilization of the ovum?

Answer 1

HCG is produced once the embryo has implanted.. Sperm and egg meet in the fallopian tube, then travel down the tube, that takes about 5-10 days then the embryo implants in the uterine lining and begins producing HCG. you can usually get a positive home test anywhere from 7-14 days after ovulation, but to avoid false negatives 14 days is recommended ~pawsalmighty

Answer 2

The production of the hCG hormone begins immediately after fertilization of the ova. hCG is a protein hormone that can be detected via a pregnancy test as little as 24 hours after implantation.

Answer 3

the earliest signs are usually 11 days. some women take longer though because production varies.
