Comparator / control treatment
No control (or placebo) treatment will be used in this study, all enrolled participants will be receiving the active treatment (i.e., Hominax). This change was made at the conclusion of the RCT (i.e., after recruiting 7 participants) and we are now recruiting male volunteers to be part of the open-label study.

Frequency of adverse events as recorded on an Adverse Events Log. The expected adverse event profile of Hominax is a combination of adverse events reported for its components, namely: constipation, diarrhoea, nausea, vomiting, headache, restlessness, stomach discomfort, loss of appetite, tremors, insomnia, shortness of breath, mild upper gastrointestinal tract infection, allergic reaction, irritability, heartburn, chest tightness, fatigue, paraesthesia, nosebleeds, decreased urine, rapid pulse, cough, heart palpitations, increased sweating. The expected rate for each of these adverse events is infrequent and the expected severity is mild to moderate. Hominax is considered relatively safe with no drug related serious adverse events expected at the prescribed dose.

Study design
Purpose of the study
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Numbered containers will be used. Bottles will be labelled with sequential randomisation ID numbers prior to the start of the trial, and each subsequent participant will be allocated the next consecutive randomisation ID number.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation sequence will be computer-generated by an independent researcher, The randomisation code will be held by an independent researcher. None of the investigators in the trial will have privy to this code until data analysis is complete.

Statistical methods / analysis
We assume that the active treatment will improve concentration, morphology and motility simultaneously. We set the lower limit of clinical significance of these improvements at 0.5 standard deviations; which we estimate to be simultaneous improvement in average concentration from 15 x106 to 20 x106, in morphology from 4% to 6% and in forward motility from 30% to 40%. We assume 0.3 correlation between each of concentration, morphology and motility and 0.5 correlation between baseline and follow-up measures. Morphology is scored between 0 to 100 per person indicating the proportion of sperm with healthy shape morphology. Similarly motility is scored between 0 and 100 per person indicating the proportion of sperm demonstrating good forward movement. Analysis will be conducted using multivariate methods (such as MANOVA). In order to detect a clinically significant improvement in sperm quality with 80% power at the 0.05 significance level requires a total sample size of 98 completed participants which requires 122 randomised participants (61 per group) to allow for an estimated 20% withdrawal rate during the study.

Secondary analyses on single outcome variables will have 80% power to detect a 0.6 standard deviation greater improvement in the treatment group than the placebo.

Analyses of semen quality will be conducted using multivariate methods (such as MANOVA) and secondary analyses on individual outcomes will be conducted using the equivalent ANOVA.

Brief summary
This is a clinical trial examining the effectiveness of a vitamin supplement, Hominax, in improving sperm health. We are testing whether Hominax can improve sperm health. It is possible that Hominax can help prevent damage to sperm. Men will be allocated to receive either Hominax for 24 weeks. Sperm samples will be tested to look for a difference in sperm health between the pre- and post-treatment.
