Andrology is the medical speciality that deals with conditions relating specifically to men. Mr Penev routinely performs procedures to help men with problems that may affect their sex life, fertility or cause discomfort and pain.

If you are suffering, contact his medical secretary who can book you in for an initial consultation. Mr Penev will recommend the best and most appropriate treatment for you. 

Below is a list of procedures that Mr Penev offers within this speciality:

Hydrocele repair

A hydrocele is a fluid filled sack found within the scrotum. It may occur after trauma or infection of the testes. A hydrocele will feel like a painless water filled balloon in the scrotum. They are usually harmless but sometimes they can be uncomfortable or embarrassing so a hydrocele repair procedure may be needed to remove it. The procedure involves an incision made in the scrotum so the fluid can be drained. The area is sewn back up in a way that prevents the hydrocele from reforming.


The frenulum is a piece of skin that attaches the foreskin to the underside of your penis. If it is too short or gets torn, sex can be painful. A frenuloplasty lengthens the frenulum by cutting and then restitching it.


A varicocele is like a varicose vein but specifically found within the testicles. It may affect one or both testicles. You may have no symptoms or just suffer from slight discomfort. It is thought that having a varicocele can affect fertility in men so a varicocelectomy may be recommended if you have been experiencing infertility. A varicocelectomy involves clipping the veins that are causing problems to stop the blood flow, therefore reducing the size of the vein. 

Penile biopsy

A penile biopsy involves removing tissue from the penis so a pathologist can look at it under a microscope to check for cancer. Symptoms that require a biopsy may include a sore that does not heal, a lump, bleeding, discharge or any changes to the skin on your penis. Mr Penev will examine you and will be able to advise if you need a biopsy which he can perform. Once the results are back, he will recommend the best course of treatment if any are needed.

Testicular cancer

Mr Penev is highly experienced in assessing and diagnosing testicular cancer. Symptoms may include a painless swelling or changes to the testicle. Whilst testicular cancer is rare and most symptoms are caused by benign conditions, it is important that any changes to the normal appearance or feeling of your testicles should be checked out. Treatment for testicular cancer is extremely effective and involves the removal of the entire testicle.


A circumcision is the removal of the foreskin. The foreskin is the piece of skin that covers the top of the penis. It is removed for medical or religious/cultural reasons. There are several medical reasons why a circumcision may be necessary and they include:

  • A tight foreskin that causes painful erections or problems urinating
  • Recurrent balanitis  (inflammation of the foreskin)
  • Cancer of the penis 

It is a fairly straightforward procedure and Mr Penev removes the foreskin using a scalpel or surgical scissors. A general anaesthetic may be used so you are asleep for the procedure or just a spinal anaesthetic so you are awake but numb from the waist down. You will usually be allowed to go home the same day of the procedure.


A vasectomy is the cutting or sealing of the tubes that carry the sperm out of the penis. This procedure aims to permanently prevent pregnancy so no other contraception is required. It is highly effective and you will still be able to enjoy sex and ejaculate but your semen will no longer have sperm in it. A vasectomy is carried out using local anaesthetic and you will be able to go home the same day. You will have tests on your semen after your procedure to check that it has worked. Mr Penev will discuss the procedure with you and answer any questions you have. It is important to take time to think about your decision as it is usually considered permanent.


All surgical procedures carry risks, although these are usually rare or minor. Mr Penev will discuss with you all the specific complications that may occur. He will answer all your questions and discuss what you can expect after your treatment.
