Objective:
The aim of our study was to evaluate the effects of ozonised olive oil (OOO) on human sperm in vitro.
Methods:
Human sperm was incubated with OOO for 20 s in vitro. The lowest concentration that completely immobilised all the sperm in 20 s without subsequent recovery of motility was recorded as the minimum effective concentration (MEC). The effects of OOO at MEC on human sperm viability, mitochondrial and acrosomal status, DNA integrity and transmission electron microscopy were observed.
Results:
Our findings demonstrate that OOO dose-dependently inhibits sperm motility. The MEC of OOO for 100% sperm immobilisation in 20 s was 6 μg/ml. Further experiments showed that sperm ultrastructure, function and DNA integrity were significantly affected after treatment with 6 μg/ml OOO in vitro.
Conclusions:
OOO has spermicidal potential and may be explored as a promising vaginal contraceptive agent.
Insights
Ozonised olive oil (OOO) demonstrates spermicidal potential, effectively immobilizing human sperm in vitro. This study suggests OOO may be a viable option for developing new vaginal contraceptive methods.
Area of Science:
- Reproductive biology
- Pharmacology
Background:
- In vitro evaluation of novel spermicidal agents is crucial for contraceptive development.
- Ozonised olive oil (OOO) has demonstrated various biological activities.
Purpose of the Study:
- To assess the in vitro effects of ozonised olive oil (OOO) on human sperm parameters.
- To determine the minimum effective concentration (MEC) of OOO for sperm immobilization.
Main Methods:
- Human sperm were incubated with varying concentrations of OOO.
- Sperm motility, viability, mitochondrial and acrosomal status, and DNA integrity were assessed.
- Transmission electron microscopy was used to evaluate sperm ultrastructure.
Main Results:
- OOO exhibited a dose-dependent inhibition of sperm motility.
- The MEC of OOO for complete sperm immobilization within 20 seconds was determined to be 6 μg/ml.
- Treatment with OOO significantly impacted sperm ultrastructure, function, and DNA integrity.
Conclusions:
- Ozonised olive oil possesses significant spermicidal properties.
- OOO shows potential as a novel vaginal contraceptive agent.
