Meet the Clydesdale. The Clydesdale breed once almost faced extinction. Even though there is little practical use for heavy horses today because their muscle power has been replaced by machinery, breeders and enthusiasts have ensured that the breed is increasing, rather diminishing in numbers.
1 Over the three decades, the twin birth rate rose by 76 percent, from 18.9 to 33.2 per 1,000 births (or from 1.9 percent to 3.3 percent of all births) (Figure 1). 2  Increases in the twin birth rate averaged more than 2 percent a year from 1980 through 2004 (peaking at more than 4 percent from 1995 to 1998).
Women cut their chances of getting pregnant by 18% while men reduced their chances of a live birth by 14%. 9, this is a good achievement, but our goal is 15 per 1,000 live births by 2015-2106, the Chief Pediatrician said. The percentage of live births with twins has decreased only slightly over time, but only in the three youngest age categories. 05 ng/mL offers best live birth chances at all ages. Live birth rates vary according to a woman's age and decline when fewer numbers of eggs are used in a single cycle of IVF treatment.
