Fertility is the ability to procreate, and it can refer to both the man and the woman. The human species does not have a high reproductive power, and even though conceiving a child is something we take for granted, there are times when months go by without becoming pregnant.
In couples under the age of 35, a one-year period is a reasonable timeframe for conceiving a child, while after 35 this period is only six months. If during this time the couple has not become pregnant, there may be an alteration and it is time to visit a specialist. The doctor will perform a fertility diagnosis in order to ascertain the origin of the problem, and depending on the results they may indicate the best assisted reproduction treatment for the couple.
