Abstract

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.

Instantaneous Velocity - II

Instantaneous velocity is the quantity that measures how fast an object is moving along its path. In other words, the instantaneous velocity of an object is the limit of the average velocity as the elapsed time approaches zero, or the derivative of displacement with respect to time. Like average velocity, the instantaneous velocity is a vector with the dimensions of length per unit time. Instantaneous velocity can have both positive and negative values. The instantaneous velocity can be...

Instantaneous Acceleration01:16

Instantaneous Acceleration

Acceleration is in the direction of the change in velocity, but it is not always in the direction of motion. When an object slows down, its acceleration is opposite to the direction of its motion. Although commonly referred to as deceleration, this causes confusion in our analysis as deceleration is not a vector, and does not point to a specific direction with respect to a coordinate system. Therefore, the term deceleration is not used. For example, when a subway train slows down, it...

Instantaneous Power01:22

Instantaneous Power

Instantaneous power is important in electrical circuits, mainly when dealing with sinusoidal input. Instantaneous power, denoted as p(t), results from the multiplication of the instantaneous voltage (v(t)) across an element and the instantaneous current (i(t)) flowing through it. This relationship adheres to the passive sign convention and represents a fundamental principle in electrical engineering.

Instantaneous Velocity - I

The average velocity during a time interval cannot tell us how fast or in what direction a particle is moving at any given time during the interval. To calculate this, it is important to know the instantaneous velocity, which is the velocity at a specific instant of time or at a specific point along the path. Instantaneous velocity is the quantity that measures how fast an object is moving along its path. In other words, the instantaneous velocity vx of an object is the limit of the average...

Instantaneous Center of Zero Velocity

General plane motion, often observed in a rolling wheel, refers to a type of movement where the wheel is simultaneously rotating and translating. This complex motion can be understood by breaking it down into individual components.
To analyze this, consider two points on the wheel: point A and point B. The absolute velocity of point B can be expressed as the vector sum of the absolute velocity of point A and the relative velocity of point B with respect to point A. To simplify this analysis,...

Sperm Transport01:15

Sperm Transport

The journey of sperm from its origin to the point of ejaculation begins within the seminiferous tubules of the testis. Here, Sertoli cells produce fluid that propels non-motile sperm through a series of conduits, starting with the straight tubules leading to the rete testis. This interconnected network of tubules acts as the initial pathway for sperm, guiding them into the efferent ductules and then into the epididymis for maturation.
The maturation phase occurs in the epididymis, where sperm...
