Answer:
If the covalent is polar its means that pair of electrons are unequally shared between both atoms.
Through electronegativity difference.
Explanation:
Covalent bond:
It is the bond which is formed by the sharing of electrons between the atoms.
It is weaker than the ionic bond. The both bonded atoms do not completely transfer the electrons but can only shares.
For example:
The bond between the both chlorine atoms Cl₂ is coavlent. Cl:Cl
The bond between the H₂ atoms is covalent. H:H
The covalent bond can be polar or non polar. When it is formed between the atoms of two different elements then electronegativity difference is created. The atom atoms with high electronegativity values attract more strongly the shared pair of electron towards it self and become partial negative while the other became partial positive. Thus bond become polar.
But this is only in case when the electronegativity difference between both atoms is 0.4 are greater. If the difference is less than 0.4 than bond is non polar.
For example:
HCl, H₂O
The polar covalent bond is present in HCl and water because of greater electronegativity difference between hydrogen and chlorine , oxygen and hydrogen.
The sperm will be immature and sperm count will be lower if the bulbourethral gland in males fails to perform its function
The bulbourethral gland or Cowper's gland, which is homologous to the Bartholin's gland in females, produces pre-ejaculate that cleanses and lubricates the urethra prior to the arrival of the semen.
The Cowper's glands or bulbourethral glands produce the first fluid that leaves the urethra in order to neutralize the acid left from the urine. The sperm like a basic or alkaline environment in order to survive. If the function of the Cowper's glands or bulbourethral glands fails to perform its function then the sperm will not get a proper medium to travel and will get diminished in the urethra and the sperm count will get reduced.

Opposite charges attract one another. The slight positive charges on the hydrogen atoms in a water molecule attract the slight negative charges on the oxygen atoms of other water molecules. This tiny force of attraction is called a hydrogen bond.
