We recently hosted a fertility facts morning with Dr Marilyn Glenville, Dr Ciara Wright and Dr John Kennedy, Medical Director at the Sims IVF clinic. We were delighted to present the latest in nutritional support for conception and prevention of recurrent miscarriage. Dr John Kennedy brought us through the basics you need to know and what tests to do. Dr Kennedy has a fantastic ability to translate complex science and break it down into simple terms. Here’s a few gems we picked up from him, dispelling some myths around your fertility.
It can be quite a blow when you first hear the term ‘infertile’ in reference to yourself or your partner. Dr Kennedy explains that the term ‘infertile’ only applies to women without a uterus or ovaries. Most couples are actually within the range of ‘subfertile’ and most people will go on to have a child, one way or another. Infertile implies the impossible, and there are lots of possibilities.
The chances of any woman getting pregnant on an ‘ideal’ month is only around 17% so don’t worry unnecessarily if it takes a little time. Your chances increase as you continue trying so most couples (around 90%) will conceive in the first year and this rises to >95% in the second year. You should seek advice if it takes longer than 12 months under the age of 35, or longer than 6 months if over the age of 35.
It is a myth that conception happens immediately, and that sperm needs to meet egg at exactly the right time on the right day. Sperm actually accumulate in the fallopian tubes, lounging about for 4-5 days. When the egg is released it travels down the tube passing through reservoirs of sperm which will try to fertilise it. This is like a conveyor belt of hopeful candidates. The egg survives for 18 hours so the best chance of having sperm reservoirs ready to go is to have regular intercourse.
Yes, it is useful to know when the most fertile period of your cycle is. No, it is not useful to have strictly timed intercourse every month as it can add a lot more stress to an already difficult situation.
Simply put, for conception you need three things: good eggs, good sperm and a good place to put them
