Thousands of couples across India go through months, sometimes years, of fertility testing. Blood tests, ultrasounds, semen analysis, and hormone panels. Everything comes back normal. And yet pregnancy does not happen.
This is the quiet frustration of unexplained infertility. And one of the most frequently overlooked reasons behind it is poor egg quality, something that standard fertility tests do not directly measure.
Why Poor Egg Quality Is Hard to Detect
There is no simple blood test that measures egg quality. AMH tells you how many follicles you have. Antral follicle count shows how many are visible on ultrasound. FSH gives a general sense of ovarian function. But none of these tells you whether the eggs inside those follicles are chromosomally normal, mitochondrially healthy, or capable of developing into a viable embryo.
Egg quality can only truly be assessed at the time of fertilisation during IVF, when embryologists can observe how eggs fertilise, how embryos divide, and how many reach the blastocyst stage.
This means that for women trying naturally, poor egg quality remains completely invisible until it shows up as failed conception cycles, early miscarriages, or IVF failure despite seemingly healthy embryos.
Signs That Poor Egg Quality May Be a Factor
1. While egg quality cannot be measured directly, certain patterns suggest it may be involved:
2. Recurrent early miscarriages, particularly in the first trimester.
3. Failed IVF cycles despite normal embryo appearance on day 3.
4. High embryo fragmentation rates were reported by the embryology lab.
5. Poor blastocyst development, with few or no embryos reaching day 5.
6. Unexplained infertility after 12 months of trying with no other identified cause.
7. History of PCOS, endometriosis, or low ovarian reserve.
The Mitochondria Connection
At the cellular level, egg quality is largely a mitochondrial story. Every mature egg contains between 100,000 and 600,000 mitochondria, far more than any other cell in the body. This is because the egg requires enormous amounts of cellular energy to complete its final maturation, survive fertilisation, and support the early divisions of the embryo before implantation.
When mitochondrial function is compromised by age, oxidative stress, hormonal imbalance, or nutritional deficiency, eggs simply do not have enough energy to complete these steps properly. The result is chromosomal errors, fertilisation failure, and poor embryo development.
Supporting mitochondrial health in the months before conception or fertility treatment is now recognised as one of the most evidence-based approaches to improving egg quality.Β
This is the science behind formulations like MITOV, India’s first mitochondrial optimiser specifically developed for female infertility and subfertility, which combines NMN, CoQ10, Astaxanthin, and complementary antioxidants to support oocyte energy and cellular health.
PCOS, Endometriosis, and Egg Quality
Women with PCOS often have eggs that mature more slowly and are more prone to chromosomal abnormalities, a direct result of the metabolic and hormonal disruption that characterises the condition. Despite having many follicles, the quality of ovulation is frequently poor.
Women with endometriosis face a different challenge. Chronic ovarian inflammation damages mature oocytes through oxidative stress; for individuals preparing to conceive after surgery, anti-inflammatory treatment must be administered first to restore follicular health.
Two types of preset experimental conditions, priority must be given to intervening in the deep cellular environment, rather than only managing symptoms, to optimize reproductive outcomes.
What Can Be Done
1. Mitochondrial support through CoQ10 and NMN can improve cellular energy production in maturing eggs.
2. Antioxidants reduce oxidative damage that accumulates in the ovarian environment.
3. Anti-inflammatory nutrition supports healthier follicular fluid, the environment in which eggs develop.
4. Hormonal optimization through proper PCOS or endometriosis management improves the quality of ovulation.
5. Structured preconception preparation, which should start at least 3 months in advance, allows these improvements to take effect before eggs are needed.
The Bottom Line.
If your fertility tests are normal but you are not getting pregnant, you should seriously consider poor egg quality. It is one of the most common, most impactful, and most under-discussed factors in female infertility.
The absence of a diagnosis is not the same as the absence of a problem. Ask your doctor specifically about egg quality and what a structured preconception preparation protocol might look like for you.
Frequently Asked Questions
1. How do I know if poor egg quality is causing my infertility?
Poor oocyte quality cannot be detected via routine blood tests or ultrasound examinations. If patients experience abnormal reproductive events, such as recurrent miscarriage or failed in vitro fertilisation (IVF) cycles, they may consult a reproductive medicine specialist for assessment and receive appropriate interventions.
2. Can poor egg quality cause recurrent miscarriage?
Indeed, relevant factors are among the most common triggers of miscarriage. Most cases of early miscarriage arise from embryonic chromosomal abnormalities, the root cause of which lies in the quality of the egg at the time of fertilisation. Improving egg quality through mitochondrial support and antioxidant supplementation is a core strategy for managing recurrent miscarriage.
3. Does PCOS always cause poor egg quality?
Polycystic Ovary Syndrome (PCOS) does not automatically cause poor egg quality; it only elevates the associated risk. The hormone and metabolic disorders triggered by PCOS interfere with egg maturation, and interventions such as providing mitochondrial support can improve the problems of delayed egg development and chromosomal abnormalities seen in these affected eggs.
4. How does MITOV help with unexplained infertility?
MITOV has received clinical approval for treating unexplained infertility, specifically targeting mitochondrial function in oocytes. Improving cellular energy in maturing eggs, it addresses one of the most common underlying causes of unexplained infertility that standard tests cannot detect.
