Effect of L-carnitine, Multivitamins and their Combination in the Treatment of Idiopathic Male Infertility #
TLDR
The results demonstrated that the combination therapy of L-carnitine and multivitamins was more efficient and produced more significant improvement in semen characteristic than either therapy alone, and that L- carnitine therapy was moreefficient than multivittamins.
Effect of L-carnitine, Multivitamins and their Combination in the Treatment of Idiopathic Male Infertility
TLDR
The results demonstrated that the combination therapy of L – carnitine and multivitamins was more efficient and produced more significant improvement in semen characteristic than either therapy alone, and that Lcarnitine therapy was moreefficient than multivittamins.
Fixed Dose Combination Therapy of Antioxidants in Treatment of Idiopathic Oligoasthenozoospermia: Results of a Randomized, Double-blind, Placebo-controlled Clinical Trial
TLDR
To assess the effectiveness and safety of fixed dose combination (FDC) of antioxidants in treatment of idiopathic oligoasthenozoospermia, a large-scale placebo-controlled, Double-blind, randomized, Parallel three arm, Multicentric trial is conducted.
The effect of treatment by L-carnitine for infertile men on semen parameters
TLDR
A variety of studies support the conclusion that LC at total daily amounts of at least 500mg  per day can significantly improve both sperm concentration and total sperm counts among men with astheno – or oligoasthenozoospermia.
Herbo-mineral supplementation in men with idiopathic oligoasthenoteratospermia : A double blind randomized placebo-controlled trial
TLDR
Treatment with Addyzoa resulted in a significant improvement in total and progressive motility in the semen of men with iOATs after 3 months of therapy, and there was no change in the sperm concentration, ROS, DFI or TAC levels.
Effect of L-carnitine and/or L-acetyl-carnitine in nutrition treatment for male infertility: a systematic review.
TLDR
The administration of LC and/or LAC may be effective in improving pregnancy rate and sperm kinetic features in patients affected by male infertility, however, the exact efficacy of carnitines on male infertility needs to be confirmed by further investigations.
Effect of pentoxifylline on semen parameters, reproductive hormones, and seminal plasma antioxidant capacity in men with idiopathic infertility: a randomized double-blind placebo-controlled study
TLDR
PTX administration significantly improves semen parameters in infertile men with idiopathic OAT and mean SOD-like and catalase-like activity in the semen of PTX group was significantly greater than in the placebo group.

Ineffectiveness of kallikrein in treatment of idiopathic male infertility: a double-blind, randomized, placebo-controlled trial.
TLDR
Kallikrein treatment at a dose of 600 IU/day leads neither to an improvement of semen variables nor does it increase the pregnancy rate of the female partners, and is therefore not suited for therapy of idiopathic male infertility.
A double blind trial of clomiphene citrate for the treatment of idiopathic male infertility
TLDR
No evidence is provided for the efficacy of clomiphene citrate for the treatment of idiopathic male infertility and there are no significant differences between the changes in semen quality during intake of either clomIPhene or placebo.
Placebo-controlled, double-blind, cross-over trial of glutathione therapy in male infertility.
TLDR
It is indicated that glutathione therapy could represent a possible therapeutical tool for both of the selected andrological pathologies and demonstrate a statistically significant positive effect on sperm motility.
Randomised trial of mesterolone versus vitamin C for male infertility. Scottish Infertility Group.
TLDR
Results indicate that mesterolone therapy given in the absence of any defined endocrinopathy is of no benefit in promoting male fertility and furthermore the authors have been unable to find any subgroup who will respond.
Antioxidant treatment of patients with asthenozoospermia or moderate oligoasthenozoospermia with high-dose vitamin C and vitamin E: a randomized, placebo-controlled, double-blind study.
TLDR
Combined high-dose antioxidative treatment with vitamins C and E did not improve conventional semen parameters or the 24-h sperm survival rate.
Treatment of severe oligospermia with human chorionic gonadotropin/human menopausal gonadotropin: a placebo-controlled, double blind trial.
TLDR
Sperm concentrations, the percentages of motile sperm, and the proportions of normally formed spermatozoa were similar in the 2 groups at all times, and it was not possible to predict the outcome of treatment based on results of GnRH and hCG tests performed before the treatment phase.
Randomised trial of clomiphene citrate treatment and vitamin C for male infertility.
TLDR
Vitamin C would seem a preferable and cheaper alternative treatment for male infertility and there was no significant difference in the wife's pregnancy rates between the 2 treatment groups.
Infertility:Treatment of male infertility: is it effective? Review and meta-analyses of published randomized controlled trials
TLDR
Only 174 published randomized treatment trials for male subfertility were found after extensive literature review, and meta-analysis was possible on seven themes, but the results appear to be unduly influenced by trials of poor quality.
Present and future therapeutic strategies for idiopathic oligozoospermia.
TLDR
The short and medium term prospects of medical treatment for IO rest mainly with improvement of investigative procedures to a higher degree of sophistication, with emphasis placed on identifying the causes rather than the results of dysfunction so that a better selection of candidates can be made.
