yes, another fertility post. sorry but some of us are affected by this and hopefully this might be one of the missing links for us

This study was carried out to monitor the effect of oral supplementation of vitamin C on various semen parameters in oligospermic, infertile, otherwise healthy individuals. Various semen parameters, including sperm motility, sperm count, and sperm morphology, were studied before and after the vitamin C treatment. A total of 13 infertile patients were included. Their ages ranged between 25 and 35 years. They had no genital infection or varicocele. Physical examination and other routine laboratory investigations were normal. General semen analysis revealed oligozoospermia (mean sperm count was 14.3 +/- 7.38 x 10(6) sperms/mL, mean sperm with normal morphology was 43 +/- 7.87%, and mean sperm motility was 31.2 +/- 9.61%). Testicular biopsy was not done. These patients received in an open trial of 1,000 mg of vitamin C twice daily for a maximum of 2 months. Results showed that the mean sperm count was increased to 32.8 +/- 10.3 x 10(6) sperms/mL (P < .001) after 2 months of vitamin C intake. The mean sperm motility was increased significantly to 60.1 +/- 8.47% (P < .001), and mean sperms with normal morphology increased significantly to 66.7 +/- 4.77% (P < .001). This study showed that vitamin C supplementation in infertile men might improve sperm count, sperm motility, and sperm morphology and might have a place as an additional supplement to improve the semen quality towards conception.

BACKGROUND: We seek to determine whether dietary and supplement intake of specific micronutrients (zinc and folate) and antioxidants (vitamins C, E and beta-carotene) is associated with semen quality. METHODS: Ninety-seven healthy, non-smoking men provided semen and were interviewed. Average daily nutrient intake from food and supplements was derived from a self-administered food frequency questionnaire. Intake levels were summarized as low, moderate and high. Semen volume, sperm concentration, total sperm count, motility, progressive motility and total progressively motile sperm count (TPMS) were measured. RESULTS: After controlling for covariates, a high intake of antioxidants was associated with better semen quality but, in almost all cases, there was no clear dose relationship in that moderate intake groups had the poorest semen quality. For example, positive associations were observed between vitamin C intake and sperm number as reflected in the higher mean count (P=0.04), concentration (P=0.05) and TPMS (P = 0.09); between vitamin E intake and progressive motility (P = 0.04) and TPMS (P = 0.05); and between beta-carotene intake and sperm concentration (P = 0.06) and progressive motility (P = 0.06). Folate and zinc intake were not associated with improved semen quality. CONCLUSIONS: In a convenience sample of healthy non-smoking men from a non-clinical setting, higher antioxidant intake was associated with higher sperm numbers and motility.
