The Relationship between Exposure to Lead-Containing Welding Fumes and the Levels of Reproductive Hormones

	Exposed (n = 85)		Non-exposed (n = 80)		P-value*
	Mean ± SD	Range	Mean ± SD	Range	P-value*
Age (year)	38.17 ± 11.04	25–50	32.82 ± 9.66	22–43	0.026
History of Welding (year)	8.77 ± 3.61	4.2–14	ND**	ND	0.017
Lead fume (mg/m³)	0.57 ± 0.12	0.20–0.73	ND	ND	0.013
Blood Lead (μg/L)	460.28 ± 93.65	150.46–589.24	10.41 ± 3.76	3.31–12.09	0.010

[i] * P < 0.05 was considered as statistically significant.

** ND: Not Detected.

Reproductive hormones levels in exposed and non-exposed groups.

	Exposed (n = 85)		Non-exposed (n = 80)		P value*
	Mean ± SD	Range	Mean ± SD	Range	P value*
FSH (mIU/ml)	9.34 ± 2.56	3.17–21.57	5.50 ± 2.19	1.61–11.42	0.024
LH (mIU/ml)	21.05 ± 6.39	5.23–31.66	12.01 ± 5.36	3.33–24.76	0.013
Testosterone (ng/ml)	2.02 ± 0.62	1.9–5.81	7.26 ± 1.84	3.73–10.35	0.019
