Gallbladder stones can cause infertility in certain cases. The gallbladder is an organ that stores bile, a fluid produced by the liver to help with digestion. If gallstones form in the gallbladder, they can block the flow of bile and lead to inflammation and infection. This inflammation can disrupt hormones needed for reproductive processes such as ovulation or implantation of an embryo and thus result in infertility. Additionally, if the inflammation continues unchecked it could eventually cause scarring and/or damage to other organs involved in fertility such as the uterus or fallopian tubes which could further increase risk of infertility. Therefore it's important that if you experience any symptoms associated with gallstones like abdominal pain, nausea, vomiting etc., you should see your doctor immediately so they can assess whether there are any underlying issues related to your fertility.
