[The influence of sexual function on the chance of pregnancy]

There is a complex association between sexual behaviour and (in)fertility. Sexual dysfunction can cause a delay in conception, but can also be the result of not conceiving. If conception is not achieved, sexual function may become disturbed and can deteriorate further as the result of the hospital fertility protocol and medical intervention. In terms of fertility, optimal sexual function is important because it increases the chance of conception. The greatest chance of conception is achieved through sexual intercourse on multiple occasions during the fertile period, particularly on days with good quality cervical mucus, with the right interval between ejaculations (not too long and not too short), adequate arousal of both partners and without the use of artificial lubricants. Time and attentiveness are particularly important in the patient-physician contact to be able to properly advise couples on these matters.
