Foul-smelling flatulence after test-tube embryo transfer

In general, test-tube embryo transfer refers to embryo transplantation. Passing particularly foul-smelling gas after embryo transfer may be related to dietary factors, successful implantation, psychological stress, medication side effects, or gastrointestinal discomfort. Patients are advised to follow medical instructions for symptomatic treatment. Specific analyses are as follows:

1. Dietary Factors

If a patient experiences notably foul-smelling flatulence after embryo transfer, it may be related to daily diet. Consuming excessive amounts of hard-to-digest or gas-producing foods can lead to this symptom. It is recommended that patients adjust their diet by eating more fresh fruits and vegetables such as bananas, apples, cabbage, and celery. A balanced intake of meat and vegetables should be maintained to ensure a nutritionally sound diet.

2. Successful Implantation

After embryo transfer, if implantation is successful, hormonal changes may occur. Early pregnancy reactions can accelerate gastrointestinal motility, increase frequency of gas passage, and cause intestinal bloating, resulting in particularly foul-smelling flatulence. This is a normal phenomenon and patients need not worry. It is advisable to rest in bed more often and avoid strenuous physical activity.

3. Psychological Stress

Embryo transfer is a highly stressful process, and emotional pressure may affect intestinal function, leading to the aforementioned symptoms. Patients are encouraged to regulate their emotions and release negative feelings appropriately—such as by listening to music, talking with friends, or engaging in moderate exercise—to help alleviate negative emotions and reduce stress.

4. Medication Side Effects

After embryo transfer, women typically need to take medications for a period to support corpus luteum function. These medications may also stimulate the intestines, potentially causing foul-smelling flatulence. This is considered normal and symptoms usually resolve after discontinuation of the medication.

5. Gastrointestinal Discomfort

After embryo transfer, consuming raw, cold, or spicy foods may lead to gastrointestinal discomfort, which can also result in particularly foul-smelling gas. Under a doctor’s guidance, patients may use medications such as compound berberine tablets or omeprazole enteric-coated capsules for treatment.

If patients experience any persistent or severe discomfort, they should seek timely medical attention at a hospital to avoid delaying diagnosis and treatment.
