Although men often remain capable of fathering a child throughout life, male fertility does decline with age. The changes are gradual compared to women, but they are scientifically proven and can significantly impact conception chances. Specialists like Dr Bhavana Mittal at Shivam IVF, widely regarded as one of the best IVF clinics in Delhi, frequently counsel couples on how male age affects reproductive outcomes and how proper evaluation can improve the chances of pregnancy
1.1 Reduced Sperm Count
Older men may show a gradual reduction in the number of sperm produced.
Lower sperm count decreases the overall probability of fertilization.
1.2 Reduced Sperm Motility
Motility refers to the ability of sperm to swim efficiently toward the egg.
With age, a higher percentage of sperm may have poor motility, reducing the chances of natural conception.
1.3 Changes in Sperm Morphology
The shape and structure of sperm (morphology) often become less optimal with age.
Abnormal morphology affects the sperm’s ability to penetrate and fertilize the egg.
2.1 Reduced Testosterone Levels
Testosterone gradually decreases after the age of 30–40.
Lower hormone levels can affect libido, erectile function, and sperm production.
2.2 Imbalance in Reproductive Hormones
Aging may alter the levels of LH, FSH, and other hormones related to fertility.
These hormonal shifts can impair sperm formation and overall fertility.
3.1 Higher Genetic Damage in Sperm
With age, sperm DNA may experience more breaks or abnormalities.
High DNA fragmentation can lead to:
Difficulty achieving pregnancy
Early miscarriages
Lower IVF success rates
3.2 Impact on Embryo Quality
DNA-damaged sperm may reduce embryo development potential.
Fertility experts at places like Shivam IVF assess sperm DNA integrity to determine the best treatment plan.
4.1 Erectile Dysfunction
Age-related issues such as hypertension, diabetes, and stress may cause erectile problems.
Difficulty achieving or maintaining an erection can prevent successful conception.
4.2 Decreased Libido
Lower testosterone and lifestyle factors can lead to reduced sexual desire.
This may directly affect the regularity of intercourse during fertile windows.
5.1 Higher Risk of Chromosomal Abnormalities
Older sperm may contribute to conditions such as:
Autism spectrum disorders
Schizophrenia
Some congenital diseases
5.2 Increased Risk of Pregnancy Complications
Advanced paternal age has been linked to a higher chance of miscarriage and pregnancy complications.
6.1 Reduced Natural Conception Rates
Studies show that couples where the male partner is above 40–45 may take longer to conceive.
6.2 Lower Success with Fertility Treatments
Treatments like IUI or IVF may show reduced success rates for older men.
However, advanced reproductive techniques at centers like Shivam IVF, under the guidance of Dr. Bhavana Mittal, can significantly improve outcomes.
7.1 Accumulated Health Issues
Conditions such as obesity, diabetes, hypertension, and heart disease become more common with age, affecting sperm health.
7.2 Long-term Exposure to Toxins
Years of smoking, alcohol consumption, pollution, and work stress contribute to declining fertility.
7.3 Lower Physical Activity
Reduced fitness levels can affect hormone balance and sexual function.
Men should consider a fertility check-up if:
They are above 35–40 years and planning a pregnancy.
Their partner has been trying to conceive for 6–12 months without success.
They have lifestyle or health issues affecting reproductive health.
