Inwinter, the influenza virus is raging. As the influenza pandemic enters a period of high incidence, the respiratory tract and pediatric outpatient clinics are crowded with people, and many people are "caught". In this regard, many expectant mothers who are undergoing or will soon undergo IVF treatment express great concern. Monitoring by the National Center for Disease Control and Prevention shows that the current influenza A (H3N2) epidemic is in a period of rapid rise and is expected to peak from mid-to-late December to early January next year. In the face of the fierce influenza A pandemic, test-tube mothers really need to be particularly vigilant. Flu is different from the common cold. It can cause strong symptoms such as high fever and body aches. However, the test-tube population is in a special physiological stage, and the body is facing the dual challenges brought by medical procedures such as ovulation promotion and embryo transfer. Prevention is the key. Among them, influenza vaccination is the preferred method, and it is recommended to complete vaccination 4 weeks before the start of the promotion cycle. Even after entering the embryo transfer stage, vaccination is still safe.
The first thing that needs to be clear is that influenza A is by no means a "big cold".
the first thing to be clear is“”.Compared with the common cold, the systemic symptoms of influenza A are severe and the local symptoms are mild, manifested by sudden high fever (up to 39℃~40℃), chills, muscle soreness, fatigue, etc., while respiratory symptoms such as nasal congestion and runny nose are relatively insignificant.H1N1 influenza is highly contagious and prone to complications such as pneumonia and myocarditis. The impact on test-tube people is far greater than that of the common cold.
It is worth noting that the current prevalent strain of influenza A H3N2 differs significantly from previous strains. People generally lack immunity to this virus. Even those who have been vaccinated or infected with the flu in the past may still become infected again.
Infection before ovulation induction If you contract H1N1 influenza before ovulation induction, it is recommended to postpone the start of the cycle.
Pre-ovulation infections

,.Actively treat first, wait until the body fully recovers, and then consider entering the cycle. It usually takes 2-3 months to recover to ensure that the virus has been cleared from the body before starting ovulation induction. Rush initiation of ovulation promotion during the infection period may affect the effect of ovulation promotion and follicle quality.

Infectionduring ovulation promotion

Ifyou have been infected with influenza A during ovulation promotion, it needs to be decided based on your body temperature: if your body temperature is below 38 ° C, you can observe it by drinking more water, resting more, etc., and the ovulation promotion cycle can usually continue. If your body temperature exceeds 38℃, you need to use antipyretic drugs carefully under the guidance of a doctor. If the body temperature remains high, the doctor may recommend canceling this cycle of egg retrieval.

Influenzaviruses may cause temporary fluctuations in luteinizing hormone (LH) levels, but there is no need to worry too much about changes in test values.

Infectionbefore and after oocyte retrieval operation

Oocyteretrieval operation is an invasive operation and has certain requirements on the patient's physical condition. If you develop flu symptoms 48 hours before surgery, especially coughing or nasal congestion, you need special attention.

Coughmay increase the risk of anesthesia, so it is necessary to follow doctor's instructions and use cough medicines carefully; patients with nasal congestion can prepare ventilated nasal patches to avoid oral breathing during the operation leading to dry mucosa.

Ifthe body temperature exceeds 38 ° C and the symptoms are severe, the doctor may recommend canceling egg retrieval. However, for patients with a large number of follicles and at risk of ovarian hyperstimulation syndrome, sometimes it is necessary to control body temperature and symptoms, try to remove the eggs, freeze all embryos, and then transplant them after the body recovers.

Infectionduring embryo transfer

Thetransplant stage is one of the most critical steps in tube therapy. If you are infected with H1N1 before transplantation: your body temperature is not higher than 38℃ and there is no serious physical discomfort, normal transplantation may be considered. If the high fever persists, it is recommended to reduce the fever first and wait for the body to recover before transplanting. If the infection occurs after transplantation, more caution is needed. If the symptoms are mild and there is no fever, it is recommended to rest more, drink more water, and observe closely. After infection with H1N1 infection after transplantation, timely communication with the attending doctor is more important than self-medication.
To prevent the "three-piece set" to prevent influenza A, remember the three magic weapons: masks, hand washing, and immunity.
“”,:,,.Be sure to wear masks when going to public places, giving priority to medical surgical masks or N95 masks; wash hands frequently and disinfect frequently, and do not share tableware; maintain indoor ventilation and open windows 2-3 times a day for about 30 minutes each time. Ensure adequate protein intake and high-quality sleep, develop the habit of going to bed early and getting up early, avoid staying up late, and enhance your body and improve your immunity. Treatment principles If you accidentally contract H1N1 influenza, the first principle is to contact your attending doctor in time, rather than force it. The harm to embryos from persistent high fever far outweighs the risk of rational medication. Medication should be carried out under the guidance of a doctor, and try to choose drugs that are relatively safe for pregnancy. If you develop serious symptoms such as persistent high fever, chest tightness, shortness of breath, and general soreness, you should go to the fever clinic immediately and inform the Reproductive Medicine Center at the same time.
Effect of influenza A on eggs andsperm
Studies have shown that the influenza virus mainly affects the respiratory system and has no significant impact on the quality of sperm and eggs.
,,.This means that even if you are infected with H1N1, it will not cause long-term damage to gametes.
,.A study showed that "almost all the small tadpoles after COVID-19 fever were wiped out," suggesting that H1N1 fever may have a similar effect. Therefore, it is recommended to suspend the tube cycle during infection, especially during the fever stage.
After the influenza A is cured, it is possible to continue tube treatment.
,.Clinical data show that there is no significant difference in pregnancy success rates between embryo transfers 7-10 days after recovery from mild influenza and those without infection.
,,.It is safer to ensure that you have fully recovered before continuing the test-tube journey.
,,.Scientific prevention and control, rational response, and maintaining a positive attitude-this is the "protective shield" for test-tube families during the influenza season.
