Answer to Question #90582 in Cell Biology for Aahmad

Question

After fertilization the embryo implants in the endometrium and begins secreting a hormone called chorionic gonadotropin (CG), e aner implantation. CG functions to prevent the corpus luteum from degenerating so that it may continue to produce estro way we could determine, without invasive methods and without visiting the doctor w pregacy Using this information, whether someone is pregnant or not?

Choices are:

Look for a means to determine presence or absence of the corpus luteum.

Use ultrasound to determine implantation of the egg.

Develop a test to detect CG in the blood.

Develop a test to detect CG in the mother's urine

Answer 1

Develop a test to detect CG in the mother's urine.

This hormone comes in the urine after the concentration of this hormone increases in blood which can be determine after 10 days from missing the date of the last month period because this hormone doubles every 2 to 3 days during the first several weeks of pregnancy. This is a noninvasive method and can be done at home by doing urine test by using pregnancy kit test.

Among the other 3 remaining options blood test is invasive method and the rest of the 2 options needs visit to a doctor.
