A Case Study on Ovulatory Dysfunction: Unraveling the Role of Luteinizing Hormone

February 15, 2024by Dr. S. F. Czar0


In our clinical practice, we recently encountered a case that shed light on the intricate relationship between ovulatory dysfunction in women and the role of Luteinizing Hormone (LH). This case study presents a detailed examination of a patient’s journey, emphasizing the diagnostic challenges, contributing factors, and the tailored treatment plan that ultimately led to a successful resolution of ovulatory dysfunction.

Case Presentation:

Patient Profile:

  • Age: 31
  • Medical History: Polycystic Ovary Syndrome (PCOS)
  • Duration of Infertility: 2 years

Clinical Presentation: The patient presented with a history of irregular menstrual cycles and difficulty conceiving for the past two years. She reported a cycle length ranging from 35 to 45 days, with inconsistent ovulation predictor kit results. Initial investigations revealed elevated levels of androgens and an ultrasound confirmed the presence of cysts on her ovaries, consistent with a diagnosis of PCOS.

Diagnostic Challenges: Given the irregularity in the patient’s menstrual cycles and inconclusive ovulation predictor test results, determining the precise timing of ovulation proved to be a challenge. Traditional methods such as basal body temperature charting and monitoring cervical mucus changes were not providing conclusive evidence of a consistent LH surge.

Investigations: Blood tests were conducted to assess hormonal levels throughout the menstrual cycle. Results revealed elevated LH levels, indicating a potential dysregulation in the LH surge associated with ovulation. Additional tests ruled out other hormonal imbalances and provided a more comprehensive understanding of the patient’s endocrine profile.

Contributing Factors: The diagnosis of PCOS played a significant role in the ovulatory dysfunction experienced by the patient. The elevated androgen levels, insulin resistance, and disrupted hormonal balance, including LH dysregulation, were identified as key contributing factors.

Treatment Plan:

  1. Lifestyle Modifications:
    • Weight management through dietary changes and regular exercise to address insulin resistance associated with PCOS.
    • Stress management techniques, including mindfulness and relaxation exercises, to mitigate the impact of chronic stress on hormonal balance.
  2. Medication:
    • Clomiphene citrate was prescribed to induce ovulation by modulating the effects of LH. The dosage was carefully titrated based on the patient’s response and monitored through hormonal assessments.
  3. Ongoing Monitoring:
    • Regular blood tests were scheduled to monitor LH levels and ensure the effectiveness of the treatment.
    • Ultrasound examinations were conducted to track follicular development and assess the response to ovulation induction.


After three menstrual cycles of the prescribed treatment plan, the patient achieved regular ovulation, as confirmed by a consistent LH surge and ultrasound evidence of mature follicle development. Subsequent attempts at conception were successful, and the patient achieved a healthy pregnancy within six months of initiating the treatment plan.


This case study highlights the importance of recognizing the impact of LH on ovulatory dysfunction, particularly in the context of conditions such as PCOS. Through a comprehensive diagnostic approach, addressing contributing factors, and implementing a personalized treatment plan, healthcare professionals can significantly improve the chances of successful ovulation and ultimately contribute to the fulfillment of a patient’s desire for a family. The case underscores the need for a multidisciplinary approach, combining lifestyle modifications, medication, and ongoing monitoring to optimize reproductive health outcomes for women facing ovulatory dysfunction.
