OPIS – A New Fertility Calculator For Couples

The University Of Aberdeen in the UK has developed a new fertility assessment tool called OPIS (Outcome Prediction In Subfertility). This tool has been designed for couples hoping to start a family with the help of assisted reproductive technologies. OPIS specially targets people considering IVF.

This online fertility calculator may help to give couples a better insight into the possible success of conceiving a child. This can support realistic expectations. It may assist couples through their IVF journey.

How Does OPIS Work?

Through a series of 8 simple questions the OPIS fertility calculator assesses the possible success rate of IVF treatments.

It takes into account factors such as the age of the woman, pregnancy history, if she has any reproductive disorders, and how long she has been trying to conceive for.

Also taken into consideration are male factor fertility problems and the type of assisted reproductive technologies being used to help conceive.

There are two parts to this fertility calculator.

OPIS Pre IVF: This calculator assesses the possibility of conceiving after one or more complete cycles of IVF treatment. It is for women who have had fresh or frozen-thawed embryo transfers following one period of ovarian simulation.

OPIS Post IVF: This calculator is for women who have had one or more complete IVF treatments following fresh embryo transfers.

It takes less than a minute to answer the questions and the fertility calculator provides a graph showing the predicted percentage of successfully conceiving a child and the possible number of cycles it would take to have a baby.

Is the OPIS Fertility Calculator Accurate?

Like any fertility calculator, the results must only be used as a guide. These tools rely on accurate data and a series of algorithms to predict success. The good news is that the data behind the OPIS tool is comprehensive. This fertility calculator incorporates ten years of clinical data gathered by the Human Fertilisation and Embryological Authority (HFEA).

The HFEA is responsible for compiling and storing data from licensed assisted reproduction clinics throughout the United Kingdom.  The IVF analytical data used by OPIS was collected between 1999 and 2009 based on treatment information and patient records.

The University Of Aberdeen has applied sophisticated statistical modelling to this routinely collected data.  Consequently it can predict the outcome of IVF treatment for couples with a good degree of accuracy.

However, it is important to understand that there are many factors that can influence fertility and the success of IVF/ICSI treatments. A healthy diet, regular exercise, good nutrition, plenty of sleep and reduced stress are all important contributors to male and female fertility.

Why Use The OPIS Fertility Calculator?

For couples that are trying to have a family and considering IVF or other assisted reproductive technologies the OPIS fertility calculator can be a useful tool. It can help to establish realistic expectations of success and guide couples when discussing their situation with a fertility specialist. As a free resource, it is certainly a tool that can be widely utilised.

It is possible that the University of Aberdeen will continue to refine the OPIS tool and incorporate more data into the analysis as it become available. This could refine the results and further improve the predictability of the OPIS fertility calculator.

Improve your fertility with micronutrients

Several micronutrients such as vitamins, vitaminoids, amino acids and trace elements have proven themselves effective in improving sperm quantity, mobility and shape. This directly translates into better overall sperm quality and therefore a higher chance of pregnancy.

A natural food supplementation therapy for men is

  • relatively inexpensive
  • effective after three to six months
  • able to increase sperm motility by up to 23%, ejaculate volume by up to 33% and sperm count by up to 215%1 “Imhof, Martin et al., “Improvement of sperm quality after micronutritient supplementation”, e-SPEN, the European e-Journal of Clinical Nutrition and Metabolism, Epub published ahead of print.”
  • without side effects

For those reasons, male fertility food supplements are most definitely recommended as the first step in the treatment of oligospermia and asthenospermia.

We have tested the best natural male fertility boosters

Also men who have not yet taken a semen analysis test will benefit from supplementing micronutrients to ensure they are able to deliver high-quality semen.

There are no contraindications or side effects to this form of natural “sperm boosting”.

An excellent and detailed overview of many studies can be found in Steven Sinclair’s Male Infertility: Nutritional and Environmental Considerations.

A considerable range of male fertility supplements available on the UK market.

However, the products differ widely in price and composition. Menfertility.org has compared 10 of them in terms of value for money and the nutrients they provide.

What are the most effective male fertility nutrients?

A multitude of studies has shown that highly dosed nutrients have potentially significant impact on overall sperm quality.

The amino acid L-arginine has been proven to increase sperm count and motility 2 “http://www.altmedrev.com/publications/5/1/28.pdf” 3http://www.ncbi.nlm.nih.gov/pubmed/7701414.

Another amino acid L-carnitine has been found to significantly improve sperm concentration (count) and motility over a relatively short period of only 8 weeks4http://www.ncbi.nlm.nih.gov/pubmed/12568837 5http://www.ncbi.nlm.nih.gov/pubmed/8085668.

Vitamin D has been shown to improve sperm count, motility and morphology6http://www.ncbi.nlm.nih.gov/pubmed/21427118.

Vitamin B9, better known as folic acid has been shown to increase count, motility and morphology7http://www.ncbi.nlm.nih.gov/pubmed/20978181.

Zinc improves the immune system and significantly improves sperm count in combination with folic acid8http://www.ncbi.nlm.nih.gov/pubmed/11872201.

Selenium in combination with vitamin E has been found to improve motility9http://www.ncbi.nlm.nih.gov/pubmed/21403799 10http://www.ncbi.nlm.nih.gov/pubmed/12623744 11http://www.ncbi.nlm.nih.gov/pubmed/8862739.

Nutrients must be applied permanently

Sperm cells take 11 weeks to mature in the testicles. Only then they are ready for ejaculation.
If you adjust your diet today it will thus take three months for the better sperm to be ready for fertilisation.
You must therefore keep the diet or supplement on an ongoing basis – ideally until your partner is pregnant or you decide for a different treatment.

All of the male fertility supplements in our great test include several of these nutrients at once, albeit at a lower dose. This is a cost-effective and convenient way making this type of fertility therapy affordable and requiring taking only one all-in-one supplement instead of many.
