FSHR Single Nucleotide Polymorphism Frequencies in Proven Fathers and Infertile Men in Southeast Turkey

Table 3

Allelic frequency in men with proven fathers (𝑛=240) and nonobstructive azoospermic (𝑛=150) and severe oligozoospermic (𝑛=120) (𝑃>.05 by 𝜒² test).

Group		Proven fathers 𝑛 (%)	Nonobstructive azoospermic 𝑛 (%)	Severe oligozoospermic 𝑛 (%)
1	A-Asn	49 (10.2)	30 (10.0)	30 (12.5)
2	A-Ser	13 (2.7)	7 (2.3)	9 (3.8)
3	G-Asn	301 (62.7)	197 (65.7)	147 (61.2)
4	G-Ser	97 (20.2)	50 (16.7)	48 (20.0)
5*	Undecided	20 (4.2)	16 (5.3)	6 (2.5)

∗Group 5 consists of alleles 1, 2, 3, and 4, which cannot be distinguished and are included in the statistical analysis as ‘‘dummy’’ variables.
