Abstract

|
Phthalate is a chemical endocrine disrupter and interfere with the action of hormones, estrogens, androgens and thyroid hormones. It also affect cardiovascular, metabolic, immune and reproductive system in the human and animals. Curcumin is antioxidant, anti-inflammatory activity and -cancer properties in the human. We studied whether phthalates damage viability, mitochondrial activity and membrane integrity of sperm in boar semen. We also treated curcumin with/without phthalates in the boar semen. Fresh boar semen was treated with phthalates and/or curcumin for examining sperm characteristics. Sperm characteristics, sperm motility, viability, mitochondrial activity, and membrane integrity were determined during storage of boar semen. Sperm motility and viability in dose-dependent manner decreased by di-n-butyl phthalate (DBP), mono-n-butyl phthalate (MBP) and di-2-ethylhexyl phthalate (DEHP, p<0.05). Phthalates also decreased mitochondrial activity and membrane integrity of sperm (p<0.05). However, sperm motility and viability were higher than untreated-curcumin when DBP, MBP and DEHP treated with a curcumin in boar semen (p<0.05). Mitochondrial activity and membrane integrity of sperm were higher in DBP- and MBP-treated semen with curcumin (p<0.05). In conclusion, phthalates can damage sperm viability and quality during the boar semen storage, and curcumin may protect the boar sperms from phthalates during storage term.
