The relationship between a woman’s fertility and her age has been widely discussed. It is well recognized that as women age, the number and quality of their eggs decline. However, the impact of age on male fertility has often been overlooked. In fact, age plays a significant role in male fertility and is attracting increasing attention.
The impact of age on male fertility
Sperm count does decrease with age, although there are significant individual variations. The normal range for sperm concentration is typically 16 million to over 200 million per milliliter of semen (according to WHO guidelines). Studies have shown that sperm concentration may decline by up to 3.3% each year, and semen volume and sperm count also show a downward trend with age. Moreover, aging affects sperm quality, including morphology, motility, and DNA integrity.
Starting around age 30, men’s testosterone levels typically decrease by about 1% per year, which can affect libido, erectile function, and interfere with sperm cell maturation. Aging also reduces sperm motility, making it more difficult for sperm to swim effectively toward and penetrate the egg. At the same time, the probability of abnormal sperm morphology increases with age, and functions such as tail propulsion and head penetration may be impaired.Furthermore, sperm DNA fragmentation tends to increase with advancing male age. This DNA damage impairs sperm function and embryonic development potential, thereby reducing the success rates of natural conception and assisted reproductive technologies.
How to enhance male fertility as they age
Aging is an inevitable and irreversible natural process, but research shows that lifestyle changes and targeted nutritional supplements can improve sperm health.
Lifestyle adjustments: Regular exercise, a balanced diet rich in antioxidants, and maintaining a healthy weight all help improve sperm quality. Avoiding smoking, limiting alcohol consumption, and reducing exposure to environmental toxins and recreational drugs can also lower the risk of sperm DNA damage.
Taking Juvenex AOS18: For the decline in spermatogenesis function caused by aging, choosing scientifically balanced nutritional supplements can effectively address this issue. Juvenex AOS18 is a special dietary food specially designed for male reproductive health. Its core formula, AOS18, is a mixture of seaweed extract and patented ingredient Reco18. It is supplemented with lycopene, flaxseed oil, ginseng, goji berry, and other extracts. Among them, AOS18 has a purity of over 98%. This active small molecule can penetrate the blood-testis barrier and directly act on the spermatogenic epithelial cells, activating spermatogonia from the source and repairing damaged spermatogenic cells due to aging or oxidative stress. It effectively improves the decline in sperm quantity, sperm vitality, and sperm DNA integrity. The relevant research results have been published in the renowned SCI journal “GUT”, and the impact factor of this journal is 24.5.
In conclusion, age has a clear impact on male fertility—not only in terms of reduced sperm quantity but also involving declines in sperm quality. Understanding these changes can help men better plan for their future families and through active lifestyle intervention combined with targeted nutritional supplementation, such as the reasonable supplementation of Juvenex AOS18, reproductive health can be effectively maintained.
