Table 2 Calculated data taken from the WHO regarding infertile women, extrapolated to men, globally ranging from 1994-2000 [9]

	Total Infertility Rate as reported by female partners (women who have had sexual intercourse but no pregnancy, ages 15-49)	Male factor only (20-30%); Female factor not involved	Male factor Involved (40-55%)	Female factor involved (50%)
Sub-Saharan Africa	14.20%^a [18]	2.84%-4.26%^b,c	2.84%-5.68% [19]	7.1%
Central/East Asia	10.23%^a [18]	2.05%-3.07%^b	3.79% [19]	5.1%
North/West Africa	21.18%^a [18]	4.24%-6.35%^b	8.47-11.65% [19]	10.6%
Latin America/Caribbean	13.70%^a [18]	2.74%-4.11%^b	7.12% [19]	6.85%

^aFemale data reported by country; we used the mean of these countries’ data to define the region’s average reported infertility.
^bMale data calculated based on the argument that while 50% of infertility is due to females, 20-30% is due to males. Specific male infertility rates for these regions are not well reported.
^cData calculated from a different source than Sub-Saharan Africa calculations in Table 1.
