Biological factors
The biological aspect of fertility is one of the most important pillars that determine the success of conception. From genetic predisposition to the natural ageing process, there are several aspects you should be aware of.
The influence of age
Age is one of the most significant biological factors affecting fertility. For women, the number and quality of eggs start to decline gradually from the age of 30, with a more noticeable decrease after 35. For men, sperm quality tends to remain stable for longer; however, fertility can also decline after the age of 40.
The role of hormonal balance
A well-regulated hormonal balance is essential for fertility. Hormones such as FSH, LH, and progesterone regulate ovulation and prepare the uterus for implantation. Disruptions in this system can make conception more challenging for both women and men.
Genetic influences
Genetic predispositions or inherited conditions can also affect fertility. Regular medical check-ups and targeted diagnostics can help identify and address potential genetic causes early on.

Health-related factors
Your overall health plays a crucial role when it comes to fertility. Medical conditions, medications, and preventive check-ups can make a significant difference.
Impact of medical conditions
Chronic conditions such as thyroid disorders, diabetes, or endometriosis can significantly affect fertility. These conditions often influence hormonal balance and reproductive function.
Regular health checks
Monitoring your cycle and having regular health check-ups can help detect potential problems early. Tests such as a fertility assessment or a semen analysis provide valuable insights into potential obstacles.
Medications and side effects
Certain medications, such as painkillers or hormone treatments, can temporarily impact fertility. It's worth discussing potential side effects with your GP, especially if you are planning to conceive.
Lifestyle and external influences
In addition to biological and health-related factors, your lifestyle plays a decisive role in fertility. Making the right adjustments can positively influence your chances of conception.
Diet and body weight
A healthy diet and maintaining an ideal body weight are essential for fertility. Both underweight and overweight can disrupt hormonal balance, affecting ovulation in women and sperm quality in men.
Smoking, alcohol, and drugs
These substances can negatively impact fertility by damaging reproductive cells. Smoking reduces egg and sperm quality, while excessive alcohol consumption can interfere with hormone regulation.
Stress management
Chronic stress affects fertility by increasing the production of stress hormones such as cortisol, which can interfere with reproductive hormones. Mindfulness exercises, meditation, and yoga can help lower stress levels.

Supportive actions and options
In addition to natural adjustments, there are various medical and technological support options that can help improve fertility. These approaches can be tailored to individual needs and offer valuable solutions when natural methods alone are not sufficient.
Medical support
Medical treatments are often a crucial step for couples who struggle to conceive naturally. Procedures such as in vitro fertilisation (IVF) allow eggs to be fertilised outside the body and then implanted into the uterus. This can be particularly helpful for women with blocked fallopian tubes or men with low sperm quality.
Hormone therapy is another key component of fertility treatment. It can help stimulate ovulation in women or correct hormonal imbalances that may hinder conception. In some cases, fertility treatment may also involve surgical interventions to remove uterine adhesions or polyps that could affect fertility.
It’s important that medical support is tailored to your needs and conducted in close consultation with fertility specialists to achieve the best possible results.
Natural support
Natural approaches can also make a significant difference in enhancing fertility. Products such as cycle-tracking apps and ovulation tests are useful tools for identifying your most fertile days. These tools help you better understand your cycle and maximise your chances of conception.
Additionally, supplements such as folic acid, omega-3 fatty acids, and specialised vitamin complexes can support reproductive health. These supplements help maintain egg and sperm quality, preparing your body optimally for pregnancy.
Herbs and natural remedies such as vitex (agnus castus), maca root, and ashwagandha may also support hormonal balance and improve fertility. Many couples have found these natural remedies beneficial, particularly when used consistently over time.
Summary
A variety of factors influence fertility, ranging from biological and health-related aspects to external lifestyle influences. With the right combination of a healthy lifestyle, regular health check-ups, and, if necessary, medical support, you can proactively work towards your goal of becoming parents.
A fertility test or cycle monitoring can provide valuable insights into your reproductive health and help you take the next steps. With patience, perseverance, and the support of your partner, you can create the best conditions for a successful pregnancy.
