It is the condition of not getting pregnant after 1 year of
unprotected and regular sexual intercourse. 15% of the couples in
the world feel the need to apply for supportive fertility
techniques.
The point not to be forgotten is that even when normal couples with
no health problems have sexual intercourse every day, in a single
menstrual period, the possibility of getting pregnant is only 25%.
After one year the possibility of pregnancy rises up to 80%.
In the cases of rare menstrual periods, 3 or more miscarriages, past
pelvic infection, small testicles of the male and the past age of
the woman a consultancy to a doctor should be made without waiting
for a year.
The reproductive potential of the women is at peak between the ages
of 20 to 30; after years the potential decreases and after 35 a
faster decrease can be observed. Extremely thin and fat people can
also encounter difficulties for getting pregnant. Also, smoking and
alcohol decreases the sperm count of the man and spoils the egg
quality of the woman.
