It is important for men to examine their testicles regularly to ensure that there aren't any unusual lumps or bumps.
Urologist and sexual health expert Dr Shingai Mutambirwa says this may help with the early detection of testicular cancer.
Dr Shingai advises that men conduct self-examinations or ask their partners to check for any irregularities.
If there are any unusual lumps or swellings, he suggest that men see a doctor and undergo medical testing.
Dr Shingai explains that testicles are linked to sperm health and advises that men keep their testicles cool.
He says that a good diet and exercise is key to healthy, quality sperm.
