PCOS & Metabolic Health

Polycystic Ovary Syndrome (PCOS) is frequently misunderstood as a simple reproductive disorder. However, reproductive endocrinology confirms that PCOS is a complex, multi-system endocrine metabolic disorder. According to Prof. (Dr.) Abha Majumdar, managing PCOS requires looking past the ovaries to address deep cellular insulin resistance and metabolic markers. This comprehensive guide outlines our specialized clinical protocols for long-term health and fertility management.

The Core Mechanism: Insulin Resistance and Hyperinsulinemia

At the center of PCOS lies insulin resistance, a condition where body tissues do not respond properly to insulin signals. Consequently, the pancreas produces excess insulin to compensate. This state of hyperinsulinemia directly alters ovarian function in two distinct ways.

First, excess insulin acts together with Luteinizing Hormone (LH) to increase androgen production in the ovarian cells. This surge in male hormones disrupts normal follicular development. Second, hyperinsulinemia suppresses the liver’s production of Sex Hormone-Binding Globulin (SHBG). As a result, more free, active testosterone circulates in the bloodstream, triggering classic symptoms like hirsutism and irregular cycles.

Our research reveals that insulin resistance affects both lean and obese individuals with PCOS. Therefore, evaluating metabolic parameters is vital for every patient. This step prevents long-term complications like Type 2 Diabetes, dyslipidemia, and cardiovascular diseases later in life.

The Link Between PCOS and Metabolic Syndrome

A significant percentage of women diagnosed with PCOS eventually meet the clinical criteria for Metabolic Syndrome. To ensure a thorough evaluation, our diagnostic protocol at Sir Ganga Ram Hospital screen patients for the following metabolic markers:

Metabolic Marker	Standard Assessment	Clinical Implication in PCOS
Glucose Intolerance	Oral Glucose Tolerance Test (OGTT) & HbA1c	Identifies hidden insulin resistance and early pre-diabetes risks.
Lipid Profile Abnormalities	Fasting Cholesterol, HDL, LDL, and Triglycerides	Evaluates risks for early atherosclerosis and cardiovascular strain.
Visceral Obesity	Waist-to-Hip Ratio & BMI Mapping	Indicates abdominal fat deposition, which drives systemic inflammation.

Furthermore, chronic low-grade systemic inflammation typically accompanies these metabolic shifts. This inflammatory state can negatively impact egg quality and alter endometrial receptivity during fertility cycles.

What is PMOS?

PMOS and PCOS are the exact same medical condition. In May 2026, a landmark consensus published in The Lancet officially renamed Polycystic Ovary Syndrome (PCOS) to Polyendocrine Metabolic Ovarian Syndrome (PMOS). The update was established by 56 global health organizations to fix a decades-long misnomer that caused delayed diagnoses and fragmented patient care.

Why the Name Was Changed:

The Inaccuracy of “Cysts”: The old name, PCOS, implied that a person must have ovarian cysts to have the condition. In reality, many women with the disorder never develop cysts. Furthermore, the fluid-filled sacs seen on ultrasounds are actually tiny, underdeveloped follicles, not pathological cysts.
A Whole-Body Focus: PCOS historically framed the condition as a narrow gynaecological or fertility issue. The new name, PMOS, shifts the clinical focus toward a multi-system endocrine and metabolic disorder which explicitly recognizes core dysfunctions like insulin resistance, weight gain, and type 2 diabetes risks.

Advanced Clinical Management Strategies

Because PCOS manifests differently in every individual, our team strictly rejects one-size-fits-all treatments. Instead, we design highly customized protocols that target each patient’s specific metabolic profile and lifestyle goals.

1. Metabolic Sensitization and Medical Management

We routinely prescribe insulin-sensitizing agents, such as Metformin, to women requiring it to correct underlying metabolic dysfunction. Metformin helps reduce circulating insulin levels. Consequently, it lowers ovarian androgen production, restores spontaneous ovulation, and improves overall egg quality. Additionally, targeted lifestyle interventions, focusing on low-glycemic nutrition and resistance training, significantly enhance the efficacy of these medical treatments.

2. Tailored Ovulation Induction Protocols

For couples facing infertility, inducing ovulation requires maximum precision to ensure safety and success. Our clinical team utilizes specific medication strategies to optimize outcomes:

First-Line Therapy: Clomiphene citrate was the first drug which was introduced to treat anovulatory PCOS. However in the recent days we prefer another drug introduced in early 2000’s called Letrozole (an aromatase inhibitor) over clomiphene citrate. Letrozole achieves higher live-birth rates and effectively prevents the multi-follicular development that causes multiple pregnancies.
Step-Up Gonadotropin Protocols: If oral medications prove insufficient, we introduce low-dose gonadotropin injections. We meticulously use a chronic low-dose step-up regimen to safely bring a single follicle to maturity.

PCOS Management During IVF: Prioritizing Patient Safety

Women with PCOS possess a high antral follicle count. Therefore, they face an elevated risk of developing Ovarian Hyperstimulation Syndrome (OHSS) during conventional IVF cycles. To eliminate this risk completely, Dr. Abha Majumdar pioneered strict safety protocols at our centre:

GnRH Antagonist Protocol: We exclusively utilize antagonist protocols for ovarian stimulation. This strategy allows us to avoid traditional long protocols that can over-stimulate sensitive ovaries.
Agonist Trigger: We use a GnRH agonist instead of hCG to trigger final oocyte maturation. This step dramatically reduces the hormonal cascade that triggers OHSS.
The Total “Freeze-All” Strategy: Following egg retrieval, we vitrify (freeze) all high-grade embryos. Our team delays the embryo transfer until the patient’s hormonal environment returns to a safe, natural state. Consequently, we maximize implantation success while keeping patient safety at 100%.

Long-Term Health Preservation

Ultimately, resolving fertility issues is only one aspect of comprehensive care. Our primary clinical objective is to safeguard a woman’s health across her entire lifespan. By correcting metabolic parameters during the reproductive years, we drastically reduce the subsequent risks of gestational diabetes during pregnancy, endometrial hyperplasia, and vascular complications in the post-menopausal phase.
