Opening: Real Consultation Scenario
A 32-year-old woman with an AMH of 1.8 ng/mL undergoing IVF due to tubal factor asked me after completing her file: "Doctor, what exactly should I pay attention to after starting the cycle? Do I have to lie down all the time? Can I exercise? What is good to eat? I'm most afraid of making a mistake at any step that could affect the outcome." This is one of the most frequently asked questions in the clinic, and it is the question this article will systematically answer.
I. Basic Timeline of an IVF Cycle
A standard IVF cycle, from starting the cycle to the pregnancy test, typically takes 4 to 6 weeks. The exact duration depends on the ovarian stimulation protocol, ovarian response speed, and embryo culture strategy. Understanding the timeline helps patients plan their life and work.
Different protocols (e.g., antagonist protocol, long protocol, mild stimulation protocol) may vary in timing, but the core stages are the same. The precautions are detailed below stage by stage.
II. Precautions During Ovarian Stimulation
Ovarian stimulation is the longest and most frequent phase of clinic visits in an IVF cycle, and it is also the stage with the most concentrated precautions.
1. Medication Use: Fixed Time, Proper Storage
Ovarian stimulation medications (FSH preparations, hMG preparations) need to be injected at a fixed time every day, with a margin of error of no more than 1 hour. Medications must be stored according to the instructions: most require refrigeration at 2–8°C, avoiding freezing and vigorous shaking. When going out for check-ups, it is recommended to carry them in an insulated bag.
Why? Stable blood concentration of the medication is the foundation for synchronous follicle development. Irregular injection times can cause hormonal fluctuations, affecting the uniformity of follicle growth and reducing the quality of retrieved eggs.
2. Monitoring Requirements: Return on Time, Do Not Adjust Yourself
Return to the clinic every 2–4 days for transvaginal ultrasound to monitor follicle size, and simultaneously have blood drawn to check estradiol, progesterone, LH, and other indicators. The doctor adjusts the dosage of stimulation medications based on follicle growth rate and hormone levels.
- Do not delay monitoring because you are afraid of trouble or taking less time off work.
- Do not increase, decrease, or stop medication on your own.
- If you experience worsening bloating or abdominal pain during monitoring, inform your doctor promptly.
3. Lifestyle Precautions
| Category | Specific Advice | Reason |
|---|---|---|
| Diet | Normal balanced diet, appropriately increase high-quality protein (fish, shrimp, eggs, milk, lean meat) | Follicle development requires protein support, but heavy supplementation is not needed |
| Exercise | Walking, gentle yoga; avoid running, aerobics, swimming, lifting heavy objects | Enlarged ovaries are prone to torsion or premature follicle rupture |
| Sleep | Ensure 7–8 hours per day, try to fall asleep before 23:00 | Staying up late affects hormone secretion rhythms |
| Intercourse | Not recommended in the mid-to-late stage of stimulation (after follicle diameter > 14mm) | Avoid follicle rupture, infection, or ovarian torsion |
| Emotions | Avoid excessive anxiety and stress | Stress can affect the hypothalamic-pituitary-ovarian axis function |
4. Risk Identification During Ovarian Stimulation
The most common risk is Ovarian Hyperstimulation Syndrome (OHSS), characterized by bloating, abdominal pain, nausea, rapid weight gain in a short period, and decreased urine output. Mild OHSS may resolve on its own, while moderate to severe cases require medical intervention.
When should you contact a doctor? Persistent worsening of bloating, significantly reduced urine output (< 1000 mL per day), difficulty breathing, or weight gain of more than 2 kg within one day.
III. Precautions Before and After Egg Retrieval
1. Preparation Before Egg Retrieval
- After the trigger injection (HCG or GnRH agonist), egg retrieval must be precisely timed at 36 hours; it cannot be earlier or later.
- Fast for 8 hours and abstain from water for 4 hours before egg retrieval (applicable for intravenous general anesthesia).
- On the day of egg retrieval, do not wear makeup, contact lenses, or jewelry.
2. Recovery After Egg Retrieval
- Observe for 2–4 hours post-surgery; you may leave if there are no abnormalities.
- Do not drive vehicles or operate precision instruments on the same day.
- Eat a light, high-protein, easily digestible diet and drink plenty of water (1500–2000 mL per day).
- Avoid strenuous exercise, sexual intercourse, bathtub bathing, and swimming for 3 days after the procedure.
3. Signs Requiring Medical Attention After Egg Retrieval
⚠️ Seek medical attention promptly if the following occur:
- Severe and persistently worsening abdominal pain not relieved by painkillers
- Vaginal bleeding exceeding menstrual flow
- Fever, chills (body temperature ≥ 38.5°C)
- Significantly reduced urine output (< 800 mL per day)
- Difficulty breathing or chest tightness when lying flat
Light brown vaginal discharge or mild bloating after egg retrieval is normal and usually resolves within 2–3 days.
IV. Precautions Before and After Embryo Transfer
1. Endometrial Preparation Before Transfer
Whether for fresh or frozen embryo transfer, the success rate is higher when the endometrial thickness reaches 7–14 mm, the morphology is type A or B, and blood flow signals are good. Before transfer, blood is drawn to check progesterone levels. Premature elevation of progesterone may indicate early endometrial transformation, requiring cancellation of the transfer cycle.
2. Life After Transfer: Normal Activity, No Bed Rest Required
The most common question after transfer is, "Do I need to lie down all the time?" The answer is no. Prolonged bed rest is not conducive to uterine blood circulation and may increase the risk of blood clots and anxiety.
- Activity: Normal walking, housework, and working are fine. Avoid running, jumping, lifting heavy objects, and prolonged standing.
- Diet: Normal balanced diet. Avoid raw, cold, spicy, irritating foods, and alcohol. There is no need to drink various "fetal stability soups" or take supplements.
- Medication: Use luteal phase support medications on time. Do not stop or change the dosage yourself. Pay attention to hygiene for vaginal medications and rotate injection sites.
- Bowel Movements: Progesterone medications after transfer can slow intestinal motility, leading to constipation. Eat more vegetables, fruits, and whole grains. If necessary, use lactulose under a doctor's guidance.
3. Common Misconceptions After Transfer
| Misconception | Reality |
|---|---|
| Prolonged bed rest | Not conducive to blood circulation, does not improve implantation rate |
| Repeatedly using early pregnancy tests | Blood can be drawn to check HCG as early as 10–12 days after transfer; tests are inaccurate and increase anxiety |
| Heavy supplementation | Normal diet is sufficient; excessive supplementation may cause gastrointestinal discomfort |
| Fear of activity | Normal activity does not affect embryo implantation |
V. Different Precautions by Age Group
Age is a key factor affecting IVF outcomes, and the focus of precautions during the cycle varies by age group.
| Age Group | Common Characteristics | Focus of Precautions |
|---|---|---|
| < 35 years | Good ovarian reserve, usually higher number of eggs retrieved | Focus on preventing OHSS; take medication on time; avoid excessive anxiety |
| 35–40 years | Declining AMH, fewer follicles | Pay attention to synchrony of follicle development; may require higher doses of stimulation medication; consider PGT |
| > 40 years | Decreased ovarian response, higher rate of embryonic aneuploidy | Require more frequent monitoring; culture embryos to blastocyst stage; genetic counseling; endometrial receptivity assessment |
Regardless of age group, individual differences are significant. The specific protocol and precautions should be based on the judgment of your primary physician.
VI. Most Easily Overlooked Details
The following details are often overlooked in clinical practice but have a practical impact on the smooth progress of the cycle.
- Medication Storage Temperature: Stimulation medications must be used within 4 hours of leaving the refrigerator or returned to refrigeration. Use an insulated bag with ice packs when going out in summer.
- Injection Site Rotation: Rotate the left and right sides and upper and lower positions for abdominal injections daily to avoid local hardening that affects absorption.
- Constipation Prevention: Start increasing dietary fiber 2 days before transfer and develop a daily bowel movement habit.
- Emotional Monitoring: Hormonal fluctuations during the cycle can easily cause mood swings. Appropriate talking, walking, and listening to music can help stabilize emotions.
- Document Preparation: Prepare original and copies of both spouses' ID cards and marriage certificates in advance for file creation.
- Medication List: If you have chronic disease medications (e.g., thyroid hormone, blood pressure medication), inform your reproductive doctor in advance and do not stop them on your own.
- Allergy History: Patients allergic to certain medications or disinfectants must register this in their medical records before starting the cycle.
VII. Answers to Frequently Asked Questions
VIII. Doctor's Advice
The core of precautions during an IVF cycle can be summarized in twelve words: Take medication on time, live normally, and monitor on schedule.
There is no need to be overly anxious or excessively rest. Maintaining a regular routine, a balanced diet, and a stable mindset is more important than any "folk remedy." Everyone's ovarian response, endometrial condition, and hormone levels are different. Please follow the individualized plan given by your primary physician for specific precautions.
If you are unsure about anything during the cycle, the most direct and effective way is to contact your reproductive center's nursing station or your primary physician, rather than searching online or listening to non-professional advice.
