SpermMobil

An innovative treatment to improve sperm motility and fertility potential for couples trying to conceive.
Helpful tools

What is SpermMobil?

At Sunfert, we use SpermMobil, a specialised medium to activate sperm in the laboratory. When applied to a sample of completely immotile sperm, it stimulates the energy reserves of live sperm, allowing them to regain motility. This makes it easier for our embryologists to distinguish viable sperm from non-viable sperm.

Hence, SpermMobil helps us to select healthy sperm for fertilisation. It is particularly valuable for sperm retrieved surgically from the testes or epididymis (TESE, MESA), or in samples with critically low or zero motility.

By enabling couples to use their own sperm, SpermMobil increases the chances of fertilising eggs, supporting personalised IVF treatment and maximising the potential for a successful pregnancy.

Who Can Benefit from SpermMobil?

SpermMobil is particularly helpful for men experiencing:

  • low sperm motility or weak sperm movement
  • previous IVF cycles with poor fertilisation rates
  • high levels of sperm DNA fragmentation, which can affect embryo quality
  • age-related declines in sperm quality

At Sunfert, we assess each patient individually. We often recommend SpermMobil alongside other fertility treatments to maximise your chances of a successful pregnancy.

How is SpermMobil Applied at Sunfert?

Step 1: Semen Collection

At Sunfert, semen collection is usually performed through masturbation in a private room at our fertility centre. Alternatively, patients may collect the necessary kit from our nursing team and provide the sample at home, in a more comfortable and familiar environment.

For patients who are unable to produce a sample naturally or have critically low sperm counts, semen can also be obtained surgically through TESA (Testicular Sperm Aspiration) or MESA (Microsurgical Epididymal Sperm Aspiration). These procedures allow us to retrieve sperm directly from the testes or epididymis.
 

Step 2: Sperm Activation with SpermMobil

Our embryology team will apply SpermMobil on the sperm sample to activate the sperm and identify those viable sperm for later use on fertilisation.

 

Step 3: Sperm Injection

Inject the selected viable sperm carefully into the egg cytoplasm with a specialised microinjection tool.

What is SpermMobil and how does it help with fertility treatment?

SpermMobil is a specialised laboratory medium used to activate immotile or non-moving sperm.

It works by stimulating the energy mechanisms within viable sperm cells, allowing them to regain motility.

This helps our embryologists identify healthy sperm more accurately for use in IVF or ICSI, ultimately supporting improved fertilisation outcomes and embryo development.

Who is suitable for SpermMobil treatment?

SpermMobil is typically recommended for men with:

  • severely reduced or zero sperm motility
  • surgically retrieved sperm (such as TESE or MESA samples)
  • previous IVF cycles with low fertilisation rates
  • concerns such as high sperm DNA fragmentation
  • age-related decline in sperm quality

A fertility specialist will assess suitability based on individual semen analysis and clinical history

How does SpermMobil improve sperm motility in the laboratory?

In Sunfert IVF laboratory, SpermMobil is applied directly to the semen sample to stimulate energy release within viable sperm cells.

This process can temporarily activate movement in otherwise immotile sperm, allowing our embryologists to distinguish living sperm from non-viable ones and select the most suitable sperm for fertilisation via IVF.

Is SpermMobil safe for sperm used in IVF or ICSI?

Yes, SpermMobil is safe as it is used strictly under controlled laboratory conditions. It does not damage sperm cells.

Instead, it helps identify and activate viable sperm within a sample, improving the selection process for fertilisation.

This supports better embryo quality and increases the likelihood of successful implantation during IVF or ICSI treatment.

The Biological Clock

This tool indicates:

  • Natural conception per month if you have no fertility issues
  • IVF success rate at the same age
  • When to seek help after months of unsuccessful attempts

If you are concerned at any stage – we recommend booking a doctor appointment or a free nurse consultation. The sooner you make a plan the better your chances in the long term.

When to seek advice early

If you have polycystic ovaries, endometriosis, or have been through a cancer diagnosis; we recommend you get in touch quickly so we can talk you through all your options and give you the greatest possible chance of success.

If you’re a single woman considering motherhood in the future; it’s best to approach us early and consider egg freezing as this can be an option for you while you have a higher ovarian reserve and healthier eggs.

Body Mass Index calculator

Being overweight or underweight can reduce fertility, so it is important to keep your body weight within the normal healthy range.

Body Mass Index (BMI) is an indication of your body weight and can be calculated by dividing weight by height. You should aim for a BMI of between 20 and 25, as this will optimise your chances of conception.

Woman’s BMI below 19

Even in these modern times, nature knows best. If a woman's BMI falls below 19, the body senses famine and ovulation is switched off to prevent the risk of having a baby with malnutrition. Excessive exercise can reduce body fat and increase muscle mass to a point where periods cease for the same reason. Risk of miscarriage is also increased in women with a low BMI.

Being underweight

If a woman's BMI falls below 19, the body senses famine and ovulation is switched off to prevent the risk of having a baby with malnutrition. Excessive exercise can reduce body fat and increase muscle mass to a point where periods cease for the same reason. Risk of miscarriage is also increased in women with a low BMI.

BMI’s greater than 30

This can reduce fertility by 50%. Pregnancy for women with a 30+ BMI is often associated with problems such as maternal diabetes, high blood pressure, big babies and increased risk of caesarean section.
