Many women who have taken ovulation injections are not very clear about how long it will take for them to ovulate. Today, the editor of No. 5.com will introduce to you how long it will take for them to ovulate after taking ovulation injections. How long will it take for them to ovulate after taking ovulation-stimulating injections?

Ovulation injection introduction

Generally speaking, among the medical methods to help pregnancy, the use of "oral ovulation pills" or "ovulation injections" is the most common method, and the main purpose is to stimulate ovulation. Dr. Guo Yili further explained that the main ingredient of the ovulation injection is follicle-stimulating hormone, which will stimulate the growth of ovarian follicles, and then more than one mature egg will be discharged (normal ovulation, only one egg each time) to increase the chance of successful fertilization. In addition, the hormones in the ovulation injection will also cause the endometrium to thicken, making it easier for the fertilized egg to implant. In the use of ovulation injections for IVF, there are "long-term" and "short-term" arrangements, and doctors use this to control the speed of egg maturation; the ultimate goal is to obtain a certain number of eggs of good quality, and then help women get pregnant earlier. As long as the ovulation injection treatment course is determined, the hospital will arrange health education to help women learn the skills of self-administering ovulation injections, so as to facilitate subsequent use at home and avoid the pain of frequent travel. In the future, only regular follow-up (ultrasound examination, dosage adjustment, etc.) is required.

Possible risks & side effects As long as medication is used, there are risks to the human body to a certain extent, and the use of ovulation injections is no exception. "Ovarian hyperstimulation syndrome" is the most common side effect, which is common in patients with polycystic ovary syndrome (cysts) and is prone to symptoms such as ascites (fluid in the abdominal cavity). In order to avoid or reduce the occurrence of this complication, it is often necessary to rely on the doctor's skills and experience. Women who receive infertility treatment have regular follow-up visits, and the probability of occurrence is usually not high; even if this symptom does occur, specialists can do the best treatment in real time.

How long does it take to ovulate after taking the ovulation injection?

Ovulation will occur within 24-48 hours. Without ovulation injections, the follicles will grow 1-2mm per day and will be released when they develop to 18-25mm. After the ovulation injection, the follicles will mature quickly and ovulation will generally occur within 24-48 hours.

Having sex when the follicles are released can greatly increase the chance of pregnancy. Therefore, if you have sex within 2-4 days after taking the ovulation-stimulating injection, the chance of pregnancy is very high.

How to determine ovulation after taking the ovulation injection

After taking the ovulation injection, the time it takes for the follicles to mature will vary due to different individual constitutions. You can more accurately determine whether ovulation is occurring by observing changes in body temperature and cervical mucus.

1. A sudden rise in basal body temperature indicates that ovulation may be occurring;

2. The cervical mucus increases and becomes stringy like egg white, indicating that you are in the ovulation period.

What should I pay attention to when taking ovulation injections?

During medication, you need to pay attention to monitoring and measure your basal body temperature every day to help understand ovarian ovulation;

Estrogen excretion measurement: After using this product for one week, collect urine or draw blood to measure estrogen every day. Use chorionic gonadotropin only 24 hours after the estrogen peak. If the estrogen value is too high, it is not advisable to give a large amount of HCG to avoid excessive stimulation of the ovaries.

Cervical mucus examination helps to understand the maturity of follicles or whether ovulation has occurred;

b-HCG immunoassay to detect early pregnancy; ⑥ For patients with high LH values, such as polycystic ovary syndrome, gonadotropin containing only FSH75 units should be used.

When this product is used to stimulate ovulation, it is easy for multiple follicles to develop at the same time, and the multiple pregnancy rate is high, so immature newborns are also common. Common adverse reactions include: ovarian hyperstimulation syndrome (OHSS). In mild cases, there is a feeling of fullness or pain in the stomach and pelvic cavity, abdominal pain, bloating, nausea, vomiting, diarrhea and other symptoms. The drug should be stopped immediately. Mild ovarian enlargement is common, which disappears within 7 to 10 days. Moderate and severe OHSS may cause ascites and pleural effusion. The ovaries enlarge to a diameter of 10 cm, and hospitalization should be carried out to avoid irreversible electrolyte disorders or even death.

If the ovaries suddenly enlarge after stimulation, multiple follicles develop, accompanied by ovarian torsion or ovarian cyst rupture, there may even be blood accumulation in the abdominal cavity. Generally, the symptoms may worsen 3 to 10 days after the injection of HCG to induce ovulation. The use of this product often increases the risk of arterial embolism. Some may have ascites, pleural effusion, arterial thromboembolism, and fever.

Ovarian enlargement and ovarian follicle rupture lead to ovarian hyperstimulation syndrome with hemoperitoneum, pain, ascites, pleural reaction, oliguria, hypotension, and occasionally polygestation and gynecomastia.
