Polycystic Ovary Syndrome (PCOS) is one of the most common hormonal disorders among women. It is a major cause of irregular menstrual cycles and delayed pregnancy due to weak or absent ovulation. Although ovulation-inducing medications are usually the first line of treatment, some women do not respond to drug therapy. In such cases, ovarian drilling becomes an effective medical option to help stimulate ovulation naturally.Ovarian drilling is a simple surgical procedure performed using laparoscopy. During the procedure, the doctor makes very small punctures on the surface of the ovary. This helps reduce the effect of elevated male hormones (androgens) and restore hormonal balance in the body. As a result, ovulation improves and the chances of pregnancy increase, especially in women with PCOS who do not respond to medications. this Dalili Medical article, we will discuss in detail the reasons for performing ovarian drilling, how the procedure is done, its success rate, possible risks, and the most important tips to increase the chances of pregnancy after the operation.

What is Ovarian Drilling?

Ovarian drilling is a simple surgical procedure performed using laparoscopy. During the procedure, the doctor makes very small punctures on the surface of the ovary using heat (electrocautery) or laser. This helps reduce the levels and effects of elevated hormones associated with Polycystic Ovary Syndrome (PCOS), especially male hormones (androgens). As a result, ovulation improves and the chances of natural pregnancy increase.

Is Ovarian Drilling Painful?

The patient does not feel any pain during the procedure because it is performed under general anesthesia. After the surgery, mild to moderate abdominal pain may occur, which is normal and usually disappears within a few days. This discomfort can be easily managed with pain medications prescribed by the doctor.

---

How Long Does Ovarian Drilling Take?

Ovarian drilling is a relatively quick procedure:

• The surgery itself takes about 20 to 40 minutes

• In most cases, the patient can leave the hospital on the same day

• Sometimes, an overnight stay may be recommended for observation

---

When Can Pregnancy Occur After Ovarian Drilling?

Pregnancy chances improve significantly after the procedure, especially when ovulation becomes regular again.

• The best chances of pregnancy are usually within the first 3 to 6 months

• The positive effects may continue for up to 12 months

• This depends on the patient’s health, age, and ovarian response

---

What is the Success Rate of Ovarian Drilling?

Success rates vary depending on individual factors, but generally:

• Improved ovulation: occurs in about 50% to 80% of cases

• Pregnancy rates: range between 40% and 60%

Factors such as age, overall health, and ovarian condition influence the outcome.

Does Ovarian Drilling Affect Ovarian Reserve?

In most cases, ovarian drilling does not significantly reduce ovarian reserve if performed correctly and carefully. However, excessive or improperly performed punctures may affect egg count. This is why it is essential to have the procedure done by an experienced laparoscopic surgeon.

---

Can PCOS Return After Ovarian Drilling?

Yes, PCOS symptoms may return in some cases after a period of time. However, many women experience improved ovulation and hormonal balance for a long duration after the procedure.

---

Is Ovarian Drilling Dangerous?

No, ovarian drilling is considered very safe, especially when performed laparoscopically by a qualified specialist. Complications are rare and usually mild and temporary.

---

Can the Procedure Be Repeated?

Yes, ovarian drilling can be repeated in selected cases, but this is uncommon. The doctor will decide based on ovarian condition and ovarian reserve, as repeated procedures may reduce egg reserve.

---

Is Ovarian Drilling Better Than Ovulation Medications?

In some cases, yes—especially if ovulation medications have failed. Ovarian drilling may help restore natural ovulation without relying on strong medications.

---

Does Ovarian Drilling Affect the Menstrual Cycle?

Yes, ovarian drilling often helps:

• Regulate menstrual cycles
