Summary
Luteal phase gonadotropin-releasing hormone agonist (GnRH-a) administration can trigger a rare but severe ovarian hyperresponse. This case highlights potential health risks and treatment delays in women undergoing in vitro fertilization (IVF).
Area of Science:
- Reproductive Endocrinology
- In Vitro Fertilization (IVF)
- Hormonal Regulation
Background:
- Reports a rare case of ovarian hyperresponse following luteal phase GnRH-agonist administration.
- Contextualizes the event within a patient undergoing IVF using a long GnRH-agonist protocol.
Purpose of the Study:
- To document and analyze a case of significant ovarian hyperresponse.
- To illustrate the potential risks associated with GnRH-agonist flare-up effect.
Main Methods:
- Case report of a 25-year-old woman undergoing ICSI for male factor infertility.
- Comparison of three ovarian stimulation cycles: two GnRH-antagonist and one long luteal GnRH-agonist protocol.
Main Results:
- The patient experienced a massive ovarian hyperresponse (estradiol 19,102 pg/ml, ovarian volume 268 cm³) after luteal GnRH-agonist administration.
- This resulted in prolonged ovarian cysts, abdominal discomfort, and necessitated cyst aspiration.
- Previous GnRH-antagonist cycles yielded significantly fewer oocytes (22 and 6).
Conclusions:
- GnRH-agonist flare-up effect can, in rare instances, lead to severe ovarian hyperresponse.
- Such events pose health risks and can significantly delay fertility treatments.
- Careful patient selection and monitoring are crucial in GnRH-agonist protocols.

Hormonal Control of the Ovarian Cycle
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

Ovarian Cycle
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle length...
Hormonal Regulation of the Menstrual Cycle
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.

Folliculogenesis
Folliculogenesis is the development of ovarian follicles, the specialized structures within the ovarian cortex where oogenesis, or egg development, occurs. This process is essential for female reproductive health and begins during fetal development when primordial follicles are formed. Each primordial follicle comprises a primary oocyte in the center, surrounded by a single layer of squamous pre-granulosa cells. These follicles remain dormant in late prophase I of meiosis until triggered by...
Target Cell Response to Hormones
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

Proliferative Phase
The proliferative phase typically occurs after menstruation and lasts between 6 to 13 days in a standard 28-day cycle. This phase involves the reconstruction of the endometrium, guided by estrogen produced by the developing ovarian follicle.
Notably, the stratum basale, the basal layer of the endometrium, including the basal parts of the uterine glands, remains unaffected by menstruation. Stem cells in this layer undergo mitosis, regenerating the stratum functionalis and thickening the...
