Problemas de eyaculaciónFor couples where the male cannot ejaculate or there is no sperm in the ejaculate, pregnancy can be achieved by means of different techniques to obtain sperm and be able to perform an Assisted Reproduction technique.

There are patients who suffer from erectile dysfunction due to diabetes, multiple sclerosis, spinal cord injury and/or other neurological disorders. For these patients, ejaculation can be induced using one of the following methods:

Vibration-induced ejaculation:

  • With the aid of a vibrator, a vibration-induced reflex ejaculation can be caused.
  • It is a non-invasive method, very simple and safe, that can be performed at home or at the doctor’s surgery.
  • Approximately 80% of patients with spinal cord injuries manage to obtain an ejaculation.
  • This technique is also useful in patients with erectile dysfunction due to diabetes, multiple sclerosis and other neurological disorders.

Electrically Induced ejaculation (Electroejaculation):

  • This technique applies a gentle electrical stimulation. This is performed at the doctor’s surgery and some patients may require an anaesthetic.
  • This technique is useful for patients who fail to respond to the vibration technique, who suffer from erectile dysfunction due to diabetes, multiple sclerosis and/or other neurological disorders.

Retrieval of sperm from testicle (TESA, TESE, PESA and MESA):

This technique has been developed for men producing sperm with low quality or no sperm in the ejaculate due to blockage or other testicular disorders. It is also used for patients suffering from erectile dysfunction due to diabetes, multiple sclerosis and/or neurological disorders; although the sperm obtained from vibration or electrical stimulation are often better quality.

The techniques available to obtain sperm in these cases are the following:

  • TESA: Testicular extraction of sperm through aspiration
  • MESA: Micro epididymal sperm aspiration.
  • TESE: Testicular sperm extraction through biopsy.
  • PESA: Percutaneous sperm aspiration.

Depending on the method for obtaining the sample and the sperm quality (sperm count and motility), the appropriate Assisted Reproduction technique will be chosen.

In patients with success with the vibration-induced reflex ejaculation, an artificial insemination procedure can be used, as the sample obtained can be of good quality.

The probabilities of achieving pregnancy after using these techniques can be as high as if there were no infertility factor in the couple.
