Each month, your body has a menstrual cycle where an egg is released from the ovaries – this is called ovulation. Ovulation occurs (on average) 14 days before the start of your period; however it’s completely normal for women to ovulate (release the egg from the ovaries) anywhere from 12-18 days before their period starts.
Once it is released from the ovary into the fallopian tube, the egg has a maximum of 24 hours to be fertilised.
Sperm can survive in the female reproductive tract for 2-3 days waiting for the egg. By accurately predicting when ovulation will occur, we can advise the right time to have sex to give the best chance of conception.
Your fertility specialist will recommend you don’t have sex for 2-3 days prior to your fertile window to allow the sperm to build up to the best levels for fertilisation.
