Each IVF clinic will have its own protocol and restrictions for sexual activity. At most clinics, the surrogate will be asked to either abstain from sexual relations entirely or to use a combination of effective barriers prior to starting any of the inject able medications and to completely abstain from the beginning of medications until cleared by the primary IVF physician. This is usually, in our experience, two weeks before and after the transfer. This will depend on the ongoing status of the pregnancy and the orders of the physician. Surrogates will also be asked to stop any heavy exercising during the medication stage and possibly throughout the pregnancy if there is difficulty with the pregnancy. This will also be determined by the primary IVF physician.
