Fluorosis is an endemic problem in many countries of world. This study was designed to see the effect of fluoride on the reproductive system and to see the role if any of vitamin D or E supplementation on it.
Sixty rabbits were divided into six equal groups. Group I was fed on standard diet, Group II vehicle treated control, Group III on sodium fluoride (NaF) 20 mg/kg body weight, Group IV on NaF + Vitamin D, Group V on NaF + vitamin E, and Group VI on NaF + vitamin D + vitamin E.
In Group III (fed on sodium fluoride) significant decrease in sperm count (P<0.001), motility (P<0.001), progressive motility (P<0.01), and epididymal weight (P<0.05) compared to control was seen that was also evident on testicular histology. With vitamin D supplementation, there was a significant improvement in the sperm count (P<0.001), motility (P<0.01), and progressive motility (P<0.05) but remained significantly lower than the control values. With vitamin E supplementation there was significant improvement in the sperm count near normal. With vitamin D and E combined supplementation there was significant improvement in both sperm count and motility near to normal.
We conclude that combined vitamin D and E treatment showed a significant improvement in reproductive functions affected by fluoride.
氟中毒是世界上许多国家的地方性问题。本研究旨在观察氟对生殖系统的影响,并观察维生素D或E补充剂(若有)对其的作用。
60只兔子被分为6个相等的组。第一组喂食标准饮食,第二组为载体处理的对照组,第三组喂食20毫克/千克体重的氟化钠(NaF),第四组喂食NaF + 维生素D,第五组喂食NaF + 维生素E,第六组喂食NaF + 维生素D + 维生素E。
与对照组相比,第三组(喂食氟化钠)的精子数量(P<0.001)、活力(P<0.001)、前向运动能力(P<0.01)和附睾重量(P<0.05)显著降低,这在睾丸组织学上也很明显。补充维生素D后,精子数量(P<0.001)、活力(P<0.01)和前向运动能力(P<0.05)有显著改善,但仍显著低于对照值。补充维生素E后,精子数量显著改善接近正常。联合补充维生素D和E后,精子数量和活力均显著改善接近正常。
我们得出结论,联合维生素D和E治疗对受氟影响的生殖功能有显著改善。
