In Vitro Fertilization
IVF is an assisted reproductive technology in which eggs and sperm are fertilized and embryos are cultured in a laboratory before an embryo is transferred into the uterus to improve the chance of pregnancy.
In vitro fertilization (IVF) is an assisted reproductive treatment in which eggs and sperm are fertilized outside the body and cultured into embryos before transfer into the uterus. The physician tailors the ovarian stimulation protocol to ovarian reserve, age, and individual circumstances.
Performed under ultrasound guidance with intravenous anesthesia in approximately 15-30 minutes.
After egg retrieval, observe fertilization and division, and culture until day 3 or day 5.
Arrange fresh or frozen embryo implantation according to the endometrium and embryo conditions.
Assess ovarian function and begin injectable ovarian stimulation medication.
1. Monitor follicle growth and maturity with ultrasound and blood tests
2. Use a GnRH antagonist
Trigger injection: administered 34-36 hours before egg retrieval
1. Transvaginal ultrasound-guided egg retrieval under intravenous sedation
2. Collection of a fresh semen sample
3. Fertilization
Embryo culture: embryos are cultured and frozen 3-7 days after egg retrieval
Fresh embryo transfer: progesterone is given after egg retrieval, followed by embryo transfer on day 3-5
A blood test confirms the result 7-9 days after transfer.
1. Situations suitable for intrauterine insemination (IUI)
(1). Patent fallopian tubes
(2). Mild male-factor sperm abnormalities
(3). Difficulty with intercourse
(4). Ovulatory dysfunction
(5). Mild endometriosis
(6). Unexplained infertility
If IUI has not succeeded after 2-3 attempts in these situations, IVF should be considered.
2. Situations suitable for IVF:
(1). Severe fallopian tube blockage
(2). Severe endometriosis
(3). Severe male-factor sperm abnormalities
(4). Multiple failed IUI attempts
(5). Advanced age or premature ovarian aging
(2). Severe endometriosis
(3). Severe male-factor sperm abnormalities
(4). Multiple failed IUI attempts
(5). Advanced age or premature ovarian aging
Statistics released by Taiwan's Health Promotion Administration in 2025 show that pregnancy and live-birth rates decline as the age of women receiving treatment increases after age 34, with a marked drop in success among women over 40. For 2023 treatment cycles, the cumulative pregnancy rate was 44.6% and the live-birth rate was 49.7%. Among women over 40 receiving IVF, the pregnancy rate was 47.2% with frozen embryo transfer versus 29% with fresh embryo transfer (from assisted reproduction statistics released by the Health Promotion Administration in December 2025). During a treatment cycle, ovarian stimulation medication can affect endometrial receptivity and reduce implantation rates with fresh embryo transfer. Frozen embryo transfer avoids this issue and may provide better pregnancy and live-birth rates.
Yes. You can work normally during treatment while attending scheduled follow-up visits and egg retrieval. Taking the day off to rest on the day of egg retrieval is recommended.
