What diseases can cause infertility

Patient's question:

Stomach pain, frequent urination for 1 year, very overweight

Doctor's answer:

Hello, if a couple has not used contraception for more than one year and remains infertile, they should undergo medical examination. The male partner should abstain from sex for 3-5 days before a semen analysis is conducted.
Medical advice: The female partner should have her hormones tested using electrochemical luminescence on days 3-5 of her menstrual period. A vaginal examination should be performed on days 3-5 after her period ends, followed by dynamic digital hysterosalpingography and 4D color vaginal ultrasound. In most cases, this can lead to a definitive diagnosis. If the cause or reason remains undetermined, further examination with an electronic hysteroscope or laparoscope may be necessary.
