Temperature after IVF

One of the functions of artificial insemination is to stimulate the production of a larger number of eggs. This affects the quality of the process itself and the development of the embryo. At this stage, intensive hormone therapy is administered, which reduces the body's resistance to infection. After in vitro fertilization, body temperature increases.

Consequences of manipulation

The body has basic defense mechanisms against foreign particles, microorganisms, and objects. The foreign object is rejected reflexively. This phenomenon is accompanied by:

  • A significant increase in basal body temperature, compared to the normal menstrual cycle.
  • A sharp surge in progesterone, delaying the onset of menstruation.
  • An increase in the "internal" warmth of the uterine walls, which is important for embryo implantation and development.

A temperature of 37°C after IVF is proof that the procedure was successful. Otherwise, the chances of embryo formation and development are reduced. The main indicator of embryo implantation and development is an increase in basal body temperature. This occurs 15 days after a missed menstrual period.

After embryo transfer, an increase in subfebrile levels is possible. It is not recommended to eliminate this phenomenon. A temperature of up to 37.5 degrees Celsius is quite common in pregnant women.

This is clear evidence that the fertilized egg has implanted in the uterine cavity.

Consequences of manipulation
Duration of the state

Duration of the state

Variations of 37 degrees and above are normal and are normally interpreted by a specialist. The range of these fluctuations depends on the following factors:

  • Failure to follow basal temperature measurement guidelines
  • Change in habits or daily routine
  • Technical errors, thermometer malfunction

If the situation persists or worsens after correcting the errors, an urgent consultation with a gynecologist or general practitioner is necessary.

The maximum acceptable temperature after fertilization is 37.5-37.6 degrees.

Indicators after embryo transfer

Indicators after embryo transfer

The temperature after the procedure depends on two factors:

  • If implantation is successful, the temperature may increase from 37 to 37.5 degrees Celsius.
  • Concomitant use of progesterone-based medications can cause similar symptoms.

A runny nose and fever after IVF are clear signs of a weakened immune system. This combination significantly reduces the chances of a healthy, high-quality pregnancy.

Measures after cryotransfer

Measures after cryotransfer

Basal readings after diagnosis may decrease for the following reasons:

  • Severe inflammatory processes
  • Low blood pressure
  • Constant fatigue, irritability

Increased readings are possible. The maximum acceptable value is 38 degrees Celsius. This phenomenon increases the risk of ectopic pregnancy, acute infectious diseases, and chronic inflammation of the pelvic organs.

Reasons for not increasing basal heat

Reasons for not increasing basal heat

If a steady or sudden decrease in basal temperature is detected, prompt medical attention is recommended. The optimal time is no more than three days after the change (below 37.1). To establish an accurate diagnosis, comprehensive tests are performed to rule out miscarriage and hormonal imbalances.

Conception is possible even with values ​​below 37.1. Once a problem is detected, the patient is hospitalized for observation.

To avoid miscarriage, it is important to accurately record temperature readings.

Rules for measuring internal heat

Rules for measuring internal heat

The thermometer is prepared in advance. Readings are recorded immediately after measurement. The following tips should be followed:

  • The first measurements are taken after sleep. The person should be well-rested. In emergency cases, measurements are allowed after 3 hours of sleep. The measurements are performed at the same time, with minimal error, using the same instrument.
  • The insertion site is discussed with the doctor. These include the vagina, mouth, and anus.
  • Measurements are taken for 5 minutes.

During in vitro fertilization, up until pregnancy, the following changes, abnormalities, and pathologies are recorded:

  • Moving to different climate zones
  • Time zone change
  • Stress, emotional instability, daily worries
  • List of medications taken
  • Change of instruments
  • Diseases accompanied by painful sensations (catarrh, tonsillitis)

Temperature after embryo transfer during IVF is recorded on a separate form.

Conclusion

The optimal basal temperature range is 37-37.5 degrees Celsius. At 36.6 degrees Celsius, embryonic development is impaired. The chances of a full-term pregnancy are reduced.

I would like to thank all the staff of the K+31 clinic. I was here for a puncture, at the wonderful doctor Sanakoeva A.V. Administrators, nurses, doctors, anesthesiologists are all professionals in their field. If someone didn't list it, I'm sorry. Because there were a lot of employees. Very sensitive to patients before and after surgery, albeit minimally invasive. Thank you for your support, understanding and kindness! This is very important! ❤️❤️❤️
