Egg quality plays a vital role in a woman's ability to conceive, carry a healthy pregnancy, and deliver a baby. It describes the genetic well-being and development potential of an egg. Although most people tend to believe that egg quality only gets worse with age, the reality is that even younger women can experience fertility problems due to the poor health of their eggs.
This article explores the key signs of poor egg quality, uncovers what could be causing poor egg quality in younger women, and highlights possible solutions and available medical support.
What is Egg Quality?
Egg quality refers to an egg’s ability to be fertilised, develop into a healthy embryo, implant in the uterus, and result in a live birth. High-quality eggs typically have the right number of chromosomes and sufficient energy reserves to support early embryonic development.
It is crucial to separate egg quality from egg quantity. Egg quantity indicates the number of eggs still present in the ovaries (ovarian reserve), whereas egg quality defines the chances of having a successful pregnancy. A woman can have a good ovarian reserve but experience difficulties if the quality of the eggs is poor.
Symptoms and Signs of Poor Egg Quality
It can be difficult to recognise symptoms of poor egg quality because they are frequently mild and are only realised when the woman is attempting conception. Nonetheless, a few of the clinical signs can be considered red flags:
Trouble conceiving even when cycles are regular- When a couple has been attempting to conceive for more than one year (six months if older than age 35), egg quality could be a factor.
Recurrent miscarriages – Chromosomal defects in the egg tend to cause early pregnancy loss.
Irregular or abnormal menstrual cycles – Irregular cycles might indicate a hormonal imbalance in the development of eggs.
Low response to fertility medication – In IVF cycles, if the ovaries yield fewer eggs than anticipated, poor egg quality might be the case.
Poor embryo development – Embryos that do not achieve the blastocyst stage or have abnormal morphology are usually associated with poor egg quality.
Hormonal markers – A low AMH (Anti-Müllerian Hormone) level indicates low ovarian reserve, whereas an elevated FSH (Follicle Stimulating Hormone) level could signify that the ovaries are not functioning well.
Causes of Poor Egg Quality
Ageing is the most well-known cause of egg quality decline, but it’s far from the only one. Let’s explore the various causes, including what could be causing poor egg quality in a younger woman.
Age-Related Decline
A woman's fertility peaks in her 20s and starts declining gradually after 30, with a sharper drop after 35. By the early 40s, the majority of eggs may have chromosomal abnormalities, reducing the chances of a successful pregnancy.
Lifestyle Factors
Smoking, excessive alcohol, poor nutrition, lack of exercise, and exposure to environmental toxins (like BPA or pesticides) can damage egg health. Chronic stress has been linked to hormonal disruptions that can impact egg maturation.
Medical Conditions
Endometriosis, polycystic ovary syndrome (PCOS), and autoimmune disorders are frequently associated with poor egg quality. Autoimmune assaults on the ovarian tissue can interfere with egg production and quality.
Genetic and Environmental Factors
Certain women are born with gene variants that influence reproductive ageing. Environmental toxins and endocrine-disrupting chemicals (EDCs) can disrupt hormonal equilibrium and oocyte growth.
Poor Egg Quality in Younger Women
One of the greatest concerns about what could be causing poor egg quality in younger women is explained by the reasons listed below:
Premature ovarian ageing – Egg quality deteriorates sooner than anticipated.
Autoimmune disorders – Diseases such as lupus or thyroid disease can impact the ovaries.
High stress and endocrine imbalance – Stress impairs ovulation and the hormonal cycles required for egg growth.
Excessive exercise or severe dieting – These may interfere with the reproductive axis and decrease fertility potential.
How Egg Quality is Diagnosed
Egg quality cannot be directly observed, but a number of tests and clinical factors aid its assessment:
AMH Test – Indicates ovarian reserve. Not a direct measure of egg quality, but decreased AMH often correlates with fewer high-quality eggs.
FSH and Estradiol Tests – High FSH levels early in the menstrual cycle may indicate the ovaries are working harder to produce eggs.
Antral Follicle Count (AFC) – Ultrasound assessment of the number of small follicles on the ovaries.
Response to Ovarian Stimulation – During IVF, failure to respond to hormone injections or low-quality embryos can indicate poor egg quality.
Donor Eggs – Donor eggs provide a viable route to pregnancy for women with significantly low egg quality.
New Treatments
Platelet-Rich Plasma (PRP) therapy – Some treatments provide PRP to stimulate ovarian function.
Mitochondrial transfer – Experimental method to enhance the energy potential of eggs utilising donor mitochondria.
