effects of alpinia officinarum hance on sex hormones and sperm quality indices in adult dogs

Nowadays, one of the primary concerns of reproductive researchers is organismal fertility (1). this study aimed to investigate the effects of consumption of alpinia officinarum hance extract on spermatogenesis in dogs. for this purpose, 20 adult dogs were divided into 4 groups of five including control group, which did not consume the extract and three other groups took doses of 150, 250, and 500 mg/kg (2, 3). at the beginning, a sample of venous blood (5 ml) and a sperm sample were collected. serum samples were used to measure testosterone, malondialdehyde, glutathione peroxidase (gpx), total anti-oxidant capacity (tac), superoxide dismutase, and catalase. to assess the effects of extract, samples were collected weekly, and after eight weeks of feeding the extract. the sperm count, plasma membrane damage, dna damage, motility, and morphological indices were also studied (2). the findings showed that the 3rd group experienced the greatest improvement in spermatogenesis when the extract dose was increased among the groups. significant increases in curvilinear velocity, straight-line velocity, path velocity, and tac were observed in the 2nd and 3rd groups, respectively. additionally, it was observed that dogs given a high dose of extract had significant increases in their levels of testosterone, gpx, and parameters like straightness/beat cross frequency throughout the course of treatment. generally, the oral consumption of alpinia officinarum hance extract was shown to benefit adult male dogs, according to our analysis of quantitative and qualitative sperm parameters as well as blood serum biochemical parameters in different treatment groups.
