What percentage of pregnancies end in clinically recognized spontaneous abortion?

5%
10-20%
30-40%
50%

The correct answer is: 10-20%

Spontaneous abortion, also known as miscarriage, is a common occurrence in pregnancies. According to research, approximately 10-20% of all pregnancies end in miscarriage. This means that for every 10 pregnancies, 1-2 will end in a spontaneous abortion. Option A is incorrect because only 5% of pregnancies that are carried to full term result in stillbirth. Option C is incorrect because it is too high of a percentage and would result in a significantly larger number of miscarriages compared to the actual research. Option D is also incorrect because it is also too high and would mean that half of all pregnancies end in miscarriage, which is not the case.
