What are the causes of infertility?
As previously mentioned regarding how natural pregnancy occurs. However, in contrast if couples are unable to conceive a baby normally, or if there is a defect, then it is consequently identified as a cause of infertility. Basically, it is found that about 30%-40% men are infertile, women about 30%-40%, both infertile man and woman about 10% and unidentifiable causes about 10%.
Causes of infertility in men: It arises mainly from abnormalities on sperm production such as low level of sperm count, low level of motile sperm, high level of abnormal sperm morphology or ejaculation problems.
Causes of infertility in women: It is mainly from irregular ovulation arising from advanced maternal age or any hormone defect affecting ovulation. If there is no egg ovulated or irregular ovulation, this will result in a reduced chance of fertilization by sperm. Other than this, the abnormal function or structure of pelvic organs such as the fallopian tube, uterus, and cervix may affect fertilization and embryo implantation resulting in an inability to get pregnant.
Apparently, the diagnosis of male and female infertility is understood in terms of common defects. Some identifiable causes can be treated by medication, surgery or assisted reproductive technology.
