  Purpose
this is a prospective randomized placebo-controlled double-blinded trial investigating the effect of plant extracts from Alpinia galanga and Punica granatum on human semen quality. The investigators hypothesize that these plant extracts will improve semen quality.

Condition Intervention
Poor Semen Quality Dietary Supplement: Extracts of Punica granatum and Alpinia galanga Dietary Supplement: Placebo

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: An Extract of Pomegranate Fruit and Galangal Rhizome Increases the Numbers of Motile Sperm: A Prospective, Randomised, Controlled, Double-Blinded Trial

Further study details as provided by Jens Fedder, Horsens Hospital:

Primary Outcome Measures:
  • Count of motile sperm per ejaculate [ Time Frame: Each participant is given plant extract for three months with flanking semen analyses. ]

Secondary Outcome Measures:
  • Morphology: percentage of morphologically abnormal sperm in the ejaculate [ Time Frame: Each participant is given plant extract for three months with flanking semen analyses. ]
    If we find an increase in the primary outcome measure in data from participants receiving plant extracts and not in those receiving placebo tablets, we wish to further investigate whether sperm morphology also improves when consuming the plant extracts, e.g. whether the percentage of abnormal sperm in an ejaculate decreases in the group of participants receiving the active plant extracts
