However, those who are pregnant or planning to become pregnant may wonder, "How will it affect the fetus? Is it safe to inject during pregnancy? and "Is it safe to give it to the fetus during pregnancy? In particular, the early stages of pregnancy are a time when the development of the fetus is greatly affected, and the safety of cosmetic procedures must be carefully considered.
In this section, the relationship between Botox injections and fertility is explained in detail from a scientific perspective, and risks, precautions, and appropriate criteria are introduced so that those who wish to become pregnant can undergo cosmetic procedures with peace of mind.

What is Botox injection?
Botox injections are one of the most widely used procedures in the field of cosmetic medicine, in which a small amount of a protein called botulinum toxin type A, extracted from the botulinum bacteria, is injected. This toxin temporarily blocks the transmission of signals from nerves to muscles and inhibits the movement of certain muscles.
As a result, it is expected to relieve wrinkles and muscle tension caused by excessive contraction of facial muscles. Originally used to treat eyelid spasms, facial spasms, and hyperhidrosis, its cosmetic effects have attracted attention, and it is now widely used for cosmetic purposes, such as wrinkle improvement and a smaller face.
Basic Effects and Coverage of Botox
The main effect of Botox injections is to improve wrinkles and reduce muscle volume by inhibiting muscle movement. Specifically, it is applied to the following areas and symptoms
- Improvement of expression wrinkles
It is effective for wrinkles caused by changes in facial expression, such as those on the forehead, between the eyebrows, at the corners of the eyes, at the base of the nose, and on the chin. Injecting Botox into these areas reduces excessive muscle contraction and makes wrinkles less noticeable. - Small face effect (reduction of gills)
A well-developed jaw muscle called the masseter muscle causes the face to appear larger. Injecting Botox into this area can be expected to reduce the volume of the muscles and clean up the facial lines. - Improvement of hyperhidrosis
Injecting Botox into areas of excessive sweat secretion, such as the underarms, palms, and soles of the feet, inhibits neurotransmission to the sweat glands and reduces sweating. - Relief of muscle tension and stiffness
Injecting Botox into shoulder and neck muscles has also been reported to relieve muscle tension and reduce symptoms of stiff shoulders and stiff necks.
| Applicable area | Expected Effects |
|---|---|
| Forehead, between the eyebrows, and at the corners of the eyes | Improvement of expression wrinkles |
| Masseter muscle (gills) | Small face effect, improvement of facial line |
| Underarms, palms of hands, soles of feet | Improvement of hyperhidrosis |
| Shoulder, neck | Relief of muscle tension and stiffness |
Thus, Botox injections are favored by many people as a treatment for a wide variety of cosmetic and medical concerns.
The Role of Botox in Cosmetic Medicine
In the field of cosmetic medicine, Botox plays an important role as a non-invasive and quick-acting procedure. Because the procedure is completed by injection alone, without the use of a scalpel, there is little downtime and minimal impact on daily life. Another appealing feature is the flexibility to adjust the injection site and amount according to the individual patient's concerns and desires.
Furthermore, Botox can be combined with other cosmetic procedures to create a synergistic effect. For example, when used in combination with hyaluronic acid injections, Botox can improve wrinkles and restore skin firmness and elasticity. In this way, Botox is positioned as an important tool that allows for a multifaceted approach in aesthetic medicine.
Why should Botox use during pregnancy be avoided?
In the pursuit of beauty, Botox injections are favored by many for their ability to improve wrinkles and create a smaller face. However, for those who are pregnant, their use requires caution. This is because data on potential effects on the fetus and safety have not been fully established.
In addition, there is little pregnancy-specific data on the extent to which botulinum toxin affects the body, and it is impossible to say with certainty that it is safe. In light of these uncertainties, many experts recommend that Botox use should be discouraged during pregnancy and prenatal care.
Reports of Effects on the Fetus in Animal Experiments
Animal studies on botulinum toxin (the active ingredient in Botox) suggest that it may affect the fetus.
- In experiments with rats, fetal weight loss and bone dysplasia were observed after high doses of botulinum toxin.
- Experiments with rabbits similarly showed delayed ossification and developmental abnormalities in the fetus.

These results are only data from animal studies and may not directly apply to humans, however, these risks cannot be completely ignored, and as long as the safety has not been confirmed, the use of Botox during pregnancy should be avoided.
Lack of safety data and ethical constraints in humans
Data on the safety of Botox in humans during pregnancy are very limited. This is because clinical trials cannot be conducted on pregnant women for ethical reasons.
Although some case reports have documented cases in which women who used Botox in early pregnancy experienced miscarriages and fetal deaths,
- Unclear if Botox is the direct cause.
- Since miscarriages occur at a certain rate to begin with, it is difficult to determine the extent to which Botox has affected the pregnancy.
It is considered to be a
It is also said that botulinum toxin may pass through the placenta, but there is no proof of this. Due to this lack of data, it is "not safe" to use botulinum toxin during pregnancy or while pregnant.
Expert Opinions and General Recommendations
Many professional and pharmaceutical company guidelines clearly state that Botox use is not recommended during pregnancy and lactation. They also recommend the following timing for the initiation of pregnancy after Botox treatment.
| gender | Recommended contraceptive period | reason |
|---|---|---|
| female | Until the end of two menstrual cycles after the procedure | Recommended as a period of time until the effects of toxins are expelled |
| masculine gender | At least 3 months after treatment | Period of time until the effect on sperm is completely eliminated. |

Thus, a certain period of contraception is recommended after Botox use for both women and men planning pregnancy. When considering cosmetic procedures during pregnancy, it is always important to consult with a physician and fully understand the risks and the procedure before making a decision.
Recommended contraceptive period before the start of fertility after Botox treatment and why it is recommended.
It is recommended that a certain period of contraception be provided after receiving Botox injections and before beginning fertility. This is because the effects of botulinum toxin (the active ingredient in Botox) on pregnancy and the fetus are not fully understood.
The early stages of pregnancy are a critical time in the development of the fetus, and safe timing must be determined in order to eliminate as many risks as possible. In particular, contraception is recommended until two menstrual periods after the last dose for women and three months after the last dose for men, so let's take a closer look at the reasons for each.
Why contraception is recommended during administration and until two menstrual periods after the last administration
One reason why women should refrain from becoming pregnant after Botox procedures is to allow time for the body to complete the elimination of botulinum toxin. Although botulinum toxin acts locally and has minimal systemic effects, the possibility of its passing through the placenta has not been completely ruled out.
If botulinum toxin should affect the fetus through the placenta, there is a possible risk of adverse effects on development. Therefore, it is necessary to ensure a period of time during which it can be determined that botulinum toxin has been completely eliminated from the body.
Early pregnancy is also a critical period from implantation to fetal organogenesis. Eliminating external influences as much as possible during the period of fertilization, implantation, and the formation of the major organs of the fetus will lead to a healthy pregnancy.
Therefore, it is recommended that contraception be continued until at least two menstrual cycles have passed and the hormonal balance has stabilized.
Why contraception is recommended during administration and for 3 months after the last administration
For men, too, it is recommended to use contraception for at least three months, rather than starting fertility immediately after Botox treatment. The reason for this is that the sperm production cycle is approximately 3 months (74 days).
Sperm are constantly being renewed, but their formation takes a certain amount of time. If botulinum toxin can affect spermatogenesis in any way, then trying to conceive during this time should be avoided. 3 months of contraception will ensure fertilization by newly produced sperm and minimize the risk to the fetus.
Furthermore, in addition to maternal health, reproductive function on the male side must be carefully considered. It is not clear whether botulinum toxin directly affects sperm, but as long as its safety has not been fully established, action must be taken to eliminate the risk.
It is especially important for couples who wish to conceive to carefully adhere to a contraceptive period to ensure that the pregnancy is as safe as possible.
Choosing a safe cosmetic procedure during pregnancy.
When planning fertility after Botox treatment, it is recommended that women use contraception until two menstrual cycles after the last dose and men use contraception for three months after the last dose. This is a safety measure to minimize the bodily elimination of botulinum toxin and its effect on the reproductive cells.
If you are considering a fertility treatment, it is important to consult with your doctor in advance and fully understand the risks before considering the procedure. Be sure to make a careful decision based on correct knowledge in order to ensure both safe fertility and cosmetic procedures.
I got Botox without realizing I was pregnant! What to do in that case?
As mentioned above, the procedure is generally not recommended during pregnancy. However, what should you do if you have received Botox without realizing it in the early stages of pregnancy?
The first important step is to take appropriate action without undue concern. This section details the possible risks and the measures recommended by the experts.
Solution 1｜Consult your doctor (obstetrician/gynecologist) immediately.
The first step in your doctor's risk assessment is to tell you exactly at what point in your pregnancy you received Botox. Although it is considered unlikely that botulinum toxin will affect the fetus, accurate information is necessary because the degree of risk varies depending on the timing of the pregnancy.
Early pregnancy (0-12 weeks) is a critical period during which fetal organs are formed, and any external factors during this period may affect the development of the fetus. Therefore,
- Find out how many weeks pregnant you are at the time you received Botox.
- Obtain additional blood tests and ultrasounds as needed.
and other actions are recommended.
It is also believed that after mid-pregnancy (13-27 weeks), the major organs of the fetus have already formed and the effect of botulinum toxin on fetal development is more limited. Therefore, although the risk is lower than in early pregnancy, it is recommended to check the growth of the fetus during regular checkups just in case.
Coping Method 2｜Report to your cosmetic surgeon as well.
It is also important to consult with the cosmetic clinic or practitioner where you received Botox to get accurate information about the procedure.
- How much Botox was injected in which areas
- Type of Botox preparation used
- Number of treatments and the interval since the last treatment
Knowing this information will make it easier for the obstetrician/gynecologist to make a risk assessment. The type of Botox andIt is advisable to consult with both the practitioner and the obstetrician/gynecologist, as the risks may vary depending on the dosage and concentration.
Coping Method 3｜Reinforce regular antenatal checkups.
If a woman undergoes Botox without realizing she is pregnant, it is recommended that fetal development be closely monitored, especially if the pregnancy is in its early stages. In addition to a normal prenatal checkup, an additional ultrasound (echocardiogram) is recommended to check for any abnormalities in fetal development.
- Is the size of the fetus appropriate?
- Are there any abnormalities in the formation of organs?
- Is there a problem with the condition of the placenta or amniotic fluid?
It is important to check these and make sure that the growth of the fetus is not affected.
Receiving Botox does not necessarily mean that additional blood tests or amniotic fluid tests are necessary. Because of the invasive nature of these tests on the fetus, it is recommended that a careful decision be made in consultation with an obstetrician/gynecologist.
Coping Method 4｜Don't be overly anxious and make calm decisions.
Many pregnant women may experience strong anxiety if they receive Botox without realizing they are pregnant. However, the data to date indicate that even if Botox is accidentally received in the early stages of pregnancy, it is unlikely to have a serious effect on the fetus.
Excessive stress during pregnancy can rather adversely affect fetal development. For example, increased secretion of stress hormones may affect the fetus through the placenta.
Therefore, it is important to consult with an obstetrician/gynecologist and make a calm decision based on correct information, while undergoing the necessary tests and consulting a physician immediately if you have any concerns.
summary
Botox injections are one of the most popular cosmetic procedures, but limited data on their safety during pregnancy and prenatal care require careful judgment. Although animal studies have suggested an effect on the fetus, there is no clear data in humans, and many experts recommend against its use before and after pregnancy. Regarding the timing of the start of fertility after the procedure, it is also recommended that women use contraception after two menstrual periods and men use contraception for three months.
When undergoing cosmetic procedures during pregnancy, it is important to consult with a physician in advance, understand the risks, and make appropriate plans. Make the best choice for yourself while gathering the latest information in order to achieve both safe fertility and cosmetic treatment.
