Hello, thanks for using HCM.
Fertility naturally decreases in women unlike in men. In men, unless they present with acquired causes of infertility
, even at older ages, they still maintain their fertility.
However, in addition to acquired causes of infertility in women, women naturally loose their fertility as they age. This decrease is related to ovarian function in which the quantity and quality of egg is affected with age. A practical test used to evaluate this is the FSH hormone concentration in blood. Very high values of FSH ( above 15 international units) collected on day 3 of menstrual cylcle usually indicate an ovary that has given up. However, such test should be done more than once as values may fluactuate from one cycle to the other with fertility likely to increased in months with reduced values.
Other possible tests for acquired causes will include ultrasound
and serologies for chlamydia, ureaplasma
Your partner will have to do a spermogram.
Best regards and hope this helps
