Infertility
Infertility primarily refers to the biological inability of a person to contribute to conception. Infertility may also refer to the state of a woman who is unable to carry a pregnancy to full term. There are many biological causes of infertility, some which may be bypassed with medical intervention. Or alternatively a couple can't get pregnant
Reproductive endocrinologists, the doctors specializing in infertility, consider a couple to be infertile if:
- The couple has not conceived after 12 months of contraceptive-free intercourse if the female is under the age of 34. 12 months is the lower reference limit for Time to Pregnancy (TTP) by the World Health Organization.
- The couple has not conceived after 6 months of contraceptive-free intercourse if the female is over the age of 35 (declining egg quality of females over the age of 35 account for the age-based discrepancy as when to seek medical intervention).
Subfertility
ouples with primary infertility have never been able to conceive,while, on the other hand, secondary infertility is difficulty conceiving after already having conceived (and either carried the pregnancy to term or had a miscarriage). Technically, secondary infertility is not present if there has been a change of partners.
