When it comes to pregnancy, female eggs are the reproductive cells that are responsible for fertilization. These eggs are produced in the ovaries and the matured eggs are released during ovulation, as a part of women’s menstrual cycle. The released eggs when fertilized with sperm, get implanted with the uterus lining, resulting in a successful pregnancy.
The size of the eggs has a direct impact on pregnancy, as it must be in optimum size and quality to form a baby, by attaining necessary nutrients. This blog will explore the minimum of egg size on pregnancy.
Normal Egg Size for Pregnancy (in mm): Understanding the Basics
Fertility Doctor usually measure the follicles, and not the actual eggs to determine the suitability for fertilization, and the ability of the embryo to develop a healthy baby. On average, the normal follicle size for pregnancy is 18 to 20 mm in diameter.
In the case of IVF treatment, retrieving eggs from the follicles of the size range 16 to 22 mm is preferred. The menstrual cycle plays a major role in determining the size of the follicles.
- In the case of a longer menstrual cycle, the normal follicle size on the day of ovulation will be around 14 to 16 mm.To increase follicle size in 2 or 3 days , certain lifestyle changes, medications, or fertility treatments may be recommended by doctors or a fertility doctor.
- In the case of shorter menstrual cycles, the follicle size on the day of ovulation will be around 20 to 22 mm.
Reasons for Small Egg Size in Ovary: What Affects You?
Age
As the women grow older and older, the quality and quantity of their eggs decrease. After 35 years of age, the ovaries start to produce fewer eggs, which either be small or less mature. This is due to less responsive hormonal signals due to age, lowering the chances of producing fully developed and healthy eggs.
Hormonal Imbalances
Hormones play a significant role in reproductive health and overall well-being. It regulates the growth and maturation of eggs. When any imbalance in reproductive hormones occurs, it will negatively affect the egg development and size. Hormonal conditions like PCOS, Low FSH, thyroid imbalances, and high prolactin levels affect the growth of follicles and the size of eggs.
Lifestyle Factors
Your way of life and eating habits have a major impact in affecting the size of eggs produced. Lack of nutrition such as vitamins and minerals in your diet results in smaller eggs and low egg quality.
Chronic stress increases cortisol levels, which when interrupted with hormone levels, disrupts the growth of eggs.
Maintaining poor body weight, such as being obese or underweight can disrupt the hormone levels, and affect the growth of eggs.
Additionally, smoking and excessive alcohol consumption cause ovarian reserve and poor egg quality, making them less viable.
Medical Conditions
If the women experience underlying health conditions such as PCOS, endometriosis, autoimmune disorders or cancer, it directly affects the egg reserve. People with this condition have few or small eggs, due to hormonal imbalance, which makes it difficult to conceive.
If Egg Size is Small Can I Get Pregnant?
Can Small Eggs Still Lead to Successful Pregnancy?
No, if the egg size is too small, that is below 16 mm, the egg is likely immature, and may not be ready for fertilization. The immature eggs cannot help in achieving pregnancy. Even if early pregnancy is achieved, the miscarriage risks and chromosomal abnormalities in the baby’s growth are very high.
The Role of Egg Quality In Conception Despite Smaller Size
Although larger and more mature eggs are more likely for a successful pregnancy, the egg of optimum quality is more crucial than the size. Eggs with good genetics have a high chance of successful pregnancy. For women with smaller follicle sizes, maintaining the quality of eggs is crucial.
How to Improve Egg Size and Quality for Better Pregnancy Chances
Dietary changes
Incorporate healthy and nutrition-rich foods into your food diet, that contain carbohydrates, proteins, vitamins, fibre, and good fats. It ensures proper functioning and maintaining your reproductive health. Including foods to improve egg quality such as fruits, vegetables, fish, and grains in your diet can improve fertility.
Maintain Healthy Weight
Sometimes the weight could impact the egg size and quality. Maintaining the body mass index between 18 to 25 is optimum for achieving pregnancy. Regular physical workouts along with an appropriate diet can be done to maintain a healthy weight.
Manage Stress
Stress could be a reason that impacts the quality and quantity of the egg, and the overall menstrual cycle. Maintaining relaxing and mindful activities such as meditation and yoga can be done to manage stress, and enhance the production of follicle size and quality.
Hydration
Drinking plenty of water along with gentle exercise, can improve blood circulation, which increases the production of eggs of adequate size and quality. Drinking at least 6 to 8 glasses of water a day, enhanced the flow of oxygen to the ovary and blood flow.
Conclusion
In summary, the size of the eggs and ovaries play a crucial role in planning for a safe and healthy pregnancy. Having abnormal-sized eggs and follicles, affects the chances of pregnancies, causing miscarriages.
The ovulation cycle, age, hormonal levels, and medical factors majorly influence the size of eggs and the chances of pregnancy. Eggs that are of size 18 to 24 mm are optimal for pregnancy, and below these levels can affect pregnancy. If the egg sizes are abnormal, it can be enhanced by lifestyle changes, and supplements, based on the advice of doctors.
FAQs
The follicle size can be monitored at home using Ovulation Predictor Kits, Basal body Temperature Charting, Self-scanning with Ultrasound Devices, physical signs and ovulation cycle patterns.
Yes, moderate exercises for at least 30 to 40 minutes with a nutrition-rich diet can improve egg quality.
