Human placental extract injection is sometimes used to treat pelvic inflammation or support uterine health. However, its safety during active pregnancy planning is not universally established. It should only be used under the direct supervision of your fertility specialist. Common side effects are usually mild and temporary, including pain, redness, or swelling at the injection site, and occasionally a mild fever or local allergic skin reaction. Do not worry, as these are manageable, but please consult your doctor to confirm if this treatment is appropriate and safe for your specific pregnancy plans.
