How long does IVF injection take?
In vitro fertilization (IVF) is a reproductive technology that combines eggs and sperm to form an embryo, and then transfers the embryo to a woman's uterus to develop into a fetus. In the process of IVF, hormone injection is a very important link, which is crucial for the successful pregnancy. So, how long does IVF injection take? The preparation, injection duration, injection frequency and injection of drugs are described in detail below.
preparation
Before IVF hormone injection, doctors will develop personalized ovulation promotion programs according to individual conditions. At this time, a series of examinations need to be carried out, including women's blood examination, B-ultrasound examination and endometrial thickness assessment, to determine whether it is suitable for IVF. Generally speaking, the preparation period is about one month.
When the doctor determines that it is suitable for IVF, he will develop a hormone injection program. This scheme varies from person to person. According to individual conditions, multiple hormones such as estrogen, progesterone and follicle stimulating hormone may be injected.
Injection duration
The duration of the injection depends on the hormone regimen and the individual's response. Generally speaking, the time from the start of the injection of ovulation promoting drugs to the removal of eggs is 10-14 days. This time includes regular injection every day and regular B ultrasound examination to determine the development of eggs.
For the injection of estrogen and progesterone, multiple cycles of ovulation promotion and luteal maintenance are generally required. This process may last about 4-6 weeks, and the specific time varies from individual to individual.
Injection frequency
The frequency of injection depends on the hormone regimen. Generally speaking, the injection of follicle stimulating hormone needs to be carried out every day, usually 1-2 times. The frequency and dose of estrogen and progesterone injection will be adjusted according to the follicular development and blood hormone levels.
In addition to hormone injection, IVF may also need other adjuvant treatments, such as anticoagulant therapy and immunomodulation therapy, and the injection frequency of these treatments may also vary depending on individual conditions.
Injecting drugs
The main drugs commonly used for IVF hormone injection include follicle stimulating hormone, estrogen and progesterone. FSH is mainly used to promote follicle growth and development, estrogen is mainly used to increase endometrial thickness, and progesterone is mainly used to maintain luteal function. These drugs need to be injected, and the specific injection dose and use time depend on the specific program.
summary
The process of IVF hormone injection includes preparation, injection duration, injection frequency and injection of drugs. The preparation generally takes about one month, and the injection duration is generally 10-14 days. The injection frequency depends on the hormone scheme. The injection drugs include follicle stimulating hormone, estrogen and progesterone. Each individual's situation is different, and the time required and specific plan may be different. Finally, through scientific hormone injection program, the success rate of IVF can be improved and the birth dream can be realized.
