The US Centers for Disease Control and Prevention (CDC) states in a latest report that the rate of twin births in the US for 2014 was monumental, but there are explanations for this. The CDC says 2014 witnessed 33.9 sets of twins per 1,000 births as against the 33.7 recorded for 2013; and this increment could soon become a normal trend to be observed everywhere.

Health analysts state that the age of new mothers in 2014 rose to 26.3 years compared to the 26 years it was in 2013. Effective sex education and access to longterm birth control products have reduced the rate of teenage pregnancies, enabling women in their 30s and 40s to be targeted for more birth rates - The Washington Post reports.

These older women tend to have more twins than teens because their bodies produce more hormones that stimulate the production of more eggs – causing a woman to have up to two or more eggs ready for instant fertilization. Another reason behind the higher number of twin births is that older women find it a little difficult to conceive babies than youths, prompting them to go for IVF.

The CDC links three-quarter of triplets and one-third of twins born in the US in 2013 to IVF procedures, and the reason for this is because fertility doctors implant as many as three viable embryos in the woman’s womb against the hope that at least one of them will be viable and result to pregnancy.

Incidentally, most older women succeed at having all the two or three embryos live, resulting in twins or triplets. Health authorities have since 1998 issued a new guideline that discouraged doctors from implanting two or three fertilized eggs, pointing out the fact that improved medical technology now makes only one embryo to result in pregnancy.
