How Does Age Affect Your Fertility? Men and Women

17 Nov 2025

Introduction

Age is one of the most important factors influencing fertility in both men and women. While women are born with a finite number of eggs, men produce sperm throughout their lives, although sperm quality gradually declines.

At Iswarya Fertility Centre, we guide couples through a comprehensive fertility evaluation, helping them understand how age affects conception and providing the right interventions to maximize success. Whether you’re planning your first child or exploring fertility preservation, understanding the impact of age is crucial.

This guide explains the effects of age on fertility, signs to watch for, and treatment options available for couples at different stages of life.

1. Female Fertility and Age

Women are born with a set number of eggs, which decline in quantity and quality over time. Age affects female fertility in several ways:

a. Egg Quantity (Ovarian Reserve)

Women in their 20s have the highest number of eggs with excellent quality.

By age 35, both egg quantity and quality begin to decline, making conception more challenging.

After 40, natural conception rates drop significantly, and the risk of chromosomal abnormalities in eggs rises.

Tests such as AMH (Anti-Müllerian Hormone) and antral follicle count help assess ovarian reserve and guide fertility planning.

b. Egg Quality

Egg quality diminishes with age, increasing the chances of miscarriage and reducing IVF success rates. At Iswarya Fertility Centre, we perform advanced testing to evaluate egg health and provide treatment strategies, including IVF and egg freezing, to preserve fertility.

c. Hormonal Changes

Hormones like FSH, LH, estrogen, and progesterone regulate ovulation and uterine preparation. Age-related fluctuations can cause irregular periods, ovulatory issues, and reduced fertility.

d. Increased Risk of Pregnancy Complications

Advanced maternal age is linked to higher risks of gestational diabetes, high blood pressure, and complications during pregnancy, making early fertility planning essential.

2. Male Fertility and Age

Men produce sperm continuously, but age-related changes can affect sperm quality:

a. Sperm Quality

  • Sperm motility and morphology gradually decline after age 40.
  • DNA fragmentation in sperm increases with age, affecting embryo quality and pregnancy outcomes.

b. Hormonal Changes

Testosterone levels decline slowly over time, which can impact libido and sperm production.

c. Fertility Risks

Older paternal age may slightly increase the risk of genetic disorders in children, though the impact is less pronounced than in women.

At Iswarya Fertility Centre, male fertility is assessed through semen analysis, hormone testing, and advanced sperm quality evaluations to identify issues early and improve treatment outcomes.

3. How Age Influences Fertility Treatments

Age determines both the approach and success rates of fertility treatments:

Women under 35: Higher natural conception rates; IVF success is generally good.

Women 35–40: May require ovulation induction, IUI, or IVF depending on ovarian reserve.

Women over 40: IVF using their own eggs may have lower success; donor eggs may be recommended.

Men over 40: IVF or ICSI may be suggested if sperm quality is compromised.

Iswarya Fertility Centre provides age-specific, evidence-based treatment plans to optimize fertility for both partners.

4. Benefits of Early Action

Early evaluation and intervention provide several advantages:

Higher treatment success: Younger eggs and healthier sperm respond better to treatments.

More options: Egg or sperm freezing preserves future fertility.

Preventing complications: Early treatment of conditions like PCOS, endometriosis, or low sperm count avoids long-term issues.

Emotional support: Understanding fertility challenges early helps reduce anxiety and uncertainty.
