Hey ,
With every medical procedure, there are pros and cons. The reason the procedure is considered might also play a factor in the answer. The most common reason would be problems with the menstrual cycle. But perhaps you could (if you can of course!) share with us the reason why in vitro fertilization(IVF) is considered.
It might also be interesting to know a bit more about your sister. For example:
• does she experience abnormal cycles?
• Does she have underlying diseases (for example auto-immune disease, pelvic inflammatory disease, PCOS or endometriosis)?
• Did she ever experience eating disorders in the past?
• How would you describe her diet?
• Is she experiencing some form of prolonged stress?
• Are there labs done she would like to share?
• How old is she?
IVF is a procedure itself is a procedure that can be experienced differently from person to person. Her current health might increase the risk of certain long-term risk outcomes.
