Such kind of sharp testicular pain can
be due to torsion testis and it needs to be ruled out as soon as possible because
it is a medical emergency. Other cause
s are excessive bicycle riding, <span style = 'background-color: #dae8f4'>hernia</span>
or kidney or ureteric stones. Some cause
s of testicle pain, including testicular torsion, can
lead to infertility
if not treated promptly. Infections also should be examined and treated right away.
I hope it helps. Take care and regards.
