In Vitro Fertilization (IVF) is a process where an egg is fertilized by sperm outside the body before the resulting embryo is transferred to the uterus. Patients often question how to maintain their normal routines during this treatment, particularly their exercise habits. Physical activity is generally beneficial and permissible throughout an IVF cycle, but it requires modification based on the specific stage of treatment. The type and intensity of movement must be adapted to each patient’s hormonal response and physical condition, requiring individualized medical guidance.
General Guidelines for Exercise During IVF
Maintaining physical activity during an IVF cycle provides significant mental and physical benefits. Gentle movement is an effective tool for stress reduction and improving overall mood during the emotional intensity of fertility treatment. Exercise also promotes healthy blood flow throughout the body, including to the reproductive organs.
The goal is moderate intensity activity, defined as an effort level where you can still comfortably hold a conversation. Low-impact options are recommended, such as daily walking, gentle swimming, or restorative yoga practices. Hydration is also a major focus, as drinking plenty of water helps manage potential side effects like bloating and supports overall health.
Activities should be limited to around 30 minutes per session to prevent overexertion and conserve energy. It is necessary to consult with the fertility clinic team before starting or continuing any exercise regimen. They provide personalized advice based on the medication protocol and the patient’s physical response to the treatment.
Activity Restrictions During Ovarian Stimulation and Retrieval
The ovarian stimulation phase, where injectable medications cause the ovaries to produce multiple follicles, is the period of highest physical risk. The ovaries become substantially enlarged, growing from their typical size to potentially two or three inches in diameter. This increase in size makes them vulnerable to ovarian torsion, a rare but serious complication.
Ovarian torsion occurs when the enlarged ovary twists on its ligaments, cutting off the blood supply and requiring emergency surgery. To mitigate this risk, any movement involving sudden jolting, twisting, or high impact must be strictly prohibited once stimulation begins. This includes running, jumping, high-intensity interval training, and contact sports.
Patients must also avoid intense core work, heavy weightlifting (especially over ten to fifteen pounds), and yoga poses involving inversions or deep torso twisting. Safe alternatives maintain physical and mental well-being without stressing the abdominal area. These include leisurely walking, gentle cycling on a stationary bike, and modified, prenatal-style yoga or stretching. Restrictions remain in place through the egg retrieval procedure and until the enlarged ovaries return to their normal size several days afterward.
Movement During the Embryo Transfer and Two-Week Wait
Following the embryo transfer, the focus shifts from avoiding physical injury to minimizing psychological stress during the two-week wait. There is no scientific evidence supporting mandatory bed rest immediately after the transfer, and completely immobilizing the body is discouraged. Light movement is encouraged to maintain healthy circulation and prevent blood clots, especially in the legs.
The recommendation is to engage in low-level, relaxing activity that supports mental well-being without causing physical strain. Slow walking, gentle stretching, and meditation are excellent choices during this period. These activities help manage the high anxiety that often accompanies this phase of treatment.
High-intensity exercise should continue to be avoided to prevent potential uterine contractions or a significant elevation of the body’s internal temperature. While light activity does not negatively impact implantation rates, excessive physical exertion can divert blood flow away from the uterus. The priority during this final stage is to maximize comfort and create a calm, supportive environment for the embryo.
