Many child-obsessed couples are often unsure of how to reconcile sex with fertility, perhaps due to perceptions of sexuality. Some couples choose to have frequent intercourse to try to increase the chances of getting pregnant, they may choose to have sex every day near the woman’s ovulation period, or even many times a day; while other couples believe that it is better to “hold back” for a period of time, to nurture their “sperm” and build up their strength. Other couples think it’s better to “hold it in” for a while to build up their “stamina” and therefore choose to have sex at long intervals. Whether these two choices are active or passive, the fact is that both extremes are very difficult to let them as they wish. People suffering from infertility usually have more significant occupational characteristics, for example, they often leave early and return late due to their work, have irregular rest and diet, work under high tension, and have no sex life for a long time.
