We look for the real cause of the problem and don’t beat around the bush.
Our therapy supports your natural cycle and helps regulate and improve it. We work in harmony with your body—without overstimulation and without egg retrieval.
Conception takes place in intimacy—not in a laboratory. When the fertile window in the natural cycle is identified and used, pregnancy can occur naturally.
We remain by your side and continue treatment during pregnancy if needed.
Comprehensive evaluations for both women and men to uncover even hidden causes. Hormonal, physical, and lifestyle factors are taken into account to enable targeted, individualized treatment and sustainably improve fertility.
Our therapy is aimed at achieving a safe, natural pregnancy, without an increased risk of multiples, premature birth, or other complications.
Favorable conditions for conception and targeted support from the very beginning create a strong foundation for a stable and healthy pregnancy.
Often, it is a combination of factors that creates an imbalance and prevents pregnancy.
A clear pathway from investigation to treatment, tailored to each cycle.
During the initial consultation, we carry out a comprehensive assessment of your medical history, hormonal systems, nutrition, immunological factors, and cycle biomarkers.
With the support of a FertilityCare practitioner, you will learn to recognise and record your cycle biomarkers.
Based on your results, we will begin a tailored treatment plan aligned with your natural cycle.
The process takes approximately 12–18 months. If successful, we will support you further in early pregnancy.
Personal stories from women and couples we’ve had the privilege of supporting.
First, it is important to understand that an abnormal semen analysis does not automatically mean that pregnancy is impossible. In restorative reproductive medicine, there are many evidence-based approaches to improving male fertility.
These include lifestyle optimization, hormonal therapy, antibiotic treatment when infections are present, and targeted use of micronutrients.
Although fertility problems are often initially attributed to the woman, a male factor is present in approximately 30–50% of cases. Therefore, medical guidelines emphasize the importance of evaluating both partners simultaneously.
Diagnostics in the male partner begin with a detailed medical history, including previous illnesses, medication use, and lifestyle factors. Smoking, alcohol consumption, nutrition, and stress are systematically assessed, as they can affect sperm quality.
Sexual health and timing of intercourse are also discussed.
The first key examination is a semen analysis, in which a sample is assessed for volume, concentration, motility, and morphology of sperm. If abnormalities are found, the test is usually repeated to improve reliability.
Depending on the results, further specialized investigations may be required, such as hormonal testing, genetic analysis, evaluation of inflammation or infection, oxidative stress assessment, and imaging of the testes.
The goal of further diagnostics is to identify underlying causes as precisely as possible, as targeted treatment can often significantly improve sperm quality and fertility.
Treatment often begins with lifestyle measures, such as balanced nutrition, achieving a healthy weight, regular physical activity, smoking cessation, and reducing alcohol consumption.
If specific abnormalities are identified, targeted treatment may be applied, such as hormonal therapy, antioxidant supplementation, or, in selected cases, surgical correction (e.g. varicocele).
By improving the underlying factors, a significant increase in the chances of conception can often be achieved.
For this reason, the FertilityCare clinic recommends early evaluation of both partners. Depending on the results, further diagnostics may take place within the clinic or in collaboration with urological or andrological specialists.
Within restorative reproductive medicine, the focus is not on bypassing problems, but on understanding and treating the underlying causes. Instead of addressing symptoms alone, the aim is to determine what the body needs to restore hormonal balance.
Fertility is viewed comprehensively. Hormonal imbalances, irregular or absent ovulation, conditions such as endometriosis or polycystic ovary syndrome (PCOS), as well as possible male factors, are assessed in relation to each other.
Lifestyle, nutrition, and stress also play an important role in hormonal balance. In addition, less obvious factors such as inflammatory processes or metabolic disturbances may have an impact. This holistic perspective creates a detailed understanding of the individual fertility situation.
If it becomes clear that ovulation does not occur regularly or spontaneously, ovulation induction may be a targeted and relatively accessible treatment option. In this approach, ovulation is stimulated or regulated using medication — always tailored to the individual cycle dynamics and hormonal situation.
The goal is to support follicle development, improve hormonal balance, and precisely time ovulation so that the fertile window can be optimally utilized.
Treatment takes place within a structured diagnostic framework, with the cycle at its center. Through systematic cycle tracking and additional investigations, hormonal patterns, ovulation timing, and possible disruptions are carefully assessed. Based on this, the therapy is individually planned and continuously adjusted.
Depending on the cause and findings, different medications may be used:
Letrozole is often used, particularly in women with PCOS, to stimulate follicle development by lowering estrogen levels and increasing FSH release.
Clomiphene citrate stimulates the hypothalamus to increase FSH and LH production.
Gonadotropins (injections) may be used if oral therapies are insufficient, providing stronger stimulation of the ovaries.
Metformin may be used in cases of insulin resistance, especially in PCOS, to improve metabolic and hormonal balance.
Ovulation may also be triggered with hCG. In the second half of the cycle, luteal phase support may be provided, for example with progesterone and, if necessary, estrogen or hCG, to support corpus luteum function and create optimal conditions for implantation.
A key element of FertilityCare is the combination of medical treatment with detailed cycle tracking. Daily observation of body signals such as cervical mucus quality, cycle length, and additional parameters provides a continuous picture of hormonal processes.
This allows precise identification of fertile days, monitoring of treatment effects, and early detection of deviations.
This close integration of observation and treatment enables an individualized, physiologically based therapy. The goal is to achieve regular, high-quality ovulation, stabilize hormonal regulation, and sustainably improve the conditions for natural conception.
Female fertility is cyclical and regulated by a finely tuned interaction of hormones. In each cycle, there is only a short window during which pregnancy can occur — the days around ovulation.
The body provides natural signals that indicate this fertile phase, such as changes in cervical mucus, cycle length, and menstrual patterns. These signals reflect hormonal balance and the progression of the cycle.
With FertilityCare, these signals are recorded daily and systematically. While an ultrasound or hormone measurement provides only a snapshot — a “photo” — cycle tracking offers a continuous overview, like a “film” of what happens throughout the entire cycle.
This makes it possible to observe ongoing processes in the ovaries and uterus.
As a result, abnormalities such as disrupted ovulation or hormonal imbalances can often be detected earlier and more precisely. These insights form the basis for targeted further diagnostics and individualized treatment, with the aim of stabilizing the cycle and improving the chances of natural conception.
When pregnancy does not occur, it often brings not only practical questions but also emotional strain. Thoughts such as “Is my body failing me?” or “Am I doing something wrong?” are common. Doubt, tension, and uncertainty may increase, especially when the cause is unclear.
In this phase, FertilityCare can offer valuable support that is both medically grounded and personal. At its core is understanding your own cycle — not as an abstract concept, but as a biological process that becomes visible and understandable through the signals of your own body.
Within FertilityCare, you learn to understand your cycle through daily observations. This includes monitoring cervical mucus, cycle length, and other physical signs. These observations are systematically recorded and provide a detailed picture of hormonal changes throughout the cycle.
For example, the quality and changes in cervical mucus reflect estrogen activity and help identify the fertile phase. After ovulation, progesterone leads to a shift in the cycle pattern, making the transition to the non-fertile phase visible.
Through these observations, a clear understanding of the different phases of the cycle emerges. This allows you to precisely identify fertile days and improve your chances of pregnancy. At the same time, you gain a deeper understanding of how your body functions, which often leads to greater confidence and trust.
A key advantage of FertilityCare is that this knowledge does not remain isolated but forms the basis for targeted medical diagnostics and treatment. Through detailed cycle analysis, potential abnormalities can be detected earlier and more precisely, such as delayed or absent ovulation, a shortened luteal phase, or signs of hormonal imbalance.
This allows investigations to be optimally timed and therapies — if needed — to be tailored to your individual cycle.
In addition, factors that influence fertility are also taken into account, such as lifestyle, nutrition, stress, sleep, and overall health. These aspects play an important role in hormonal balance. Even small changes can have a positive effect on the cycle and overall well-being.
The strength of this approach lies in the combination of medical expertise and personal support. You learn not only what is happening in your body, but also when and why. This enables you, together with your healthcare providers, to make informed decisions and move forward on your path to pregnancy with greater confidence and clarity.
Ovulation induction treatment can vary depending on the underlying cause and the patient’s medical situation. The most common treatment options include:
Clomiphene citrate (Clomid) — this oral medication is often used as a first-line treatment. It stimulates the hypothalamus to release more FSH and LH, allowing multiple follicles to mature and increasing the chance of ovulation.
Gonadotropins (injections) — if clomiphene citrate is not effective, gonadotropins (injections of FSH and/or LH) may be used. These hormones directly stimulate the ovaries to produce eggs and are often prescribed when stronger stimulation is required, such as in women with reduced ovarian reserve.
Letrozole — this medication is frequently used in women with PCOS, as it stimulates ovulation by reducing estrogen production, which increases FSH release.
Metformin — in women with PCOS, metformin (a medication commonly used for diabetes) may be prescribed to improve insulin sensitivity and support ovulation.
A healthy, well-functioning cycle is central to fertility treatment. In addition to medical therapies, FertilityCare places strong emphasis on lifestyle factors, as these have a significant influence on hormonal balance and fertility.
It is increasingly clear that aspects such as nutrition, physical activity, and stress management play an important role in fertility and in restoring regular ovulation.
A healthy body weight is essential. Both underweight and overweight can disrupt hormonal balance and reduce the likelihood of ovulation. In certain cases, it may be beneficial to adjust weight in a responsible and guided manner.
Other factors such as stress, sleep, physical activity, nutrition, smoking, and alcohol consumption are also taken into account. These lifestyle factors can significantly influence hormonal regulation and, therefore, the cycle and ovulation.
Together, it is assessed which factors are relevant in your personal situation and where targeted improvements can be made. We support you with tailored strategies, evidence-based information, and individualized guidance on lifestyle and nutrition.
Treatment is fully tailored to your situation and combines medical therapy with personal support. This creates a comprehensive approach aimed at stabilizing hormonal balance and improving the chances of a successful pregnancy.

Video material is also available, explaining the method and its scientific background in an accessible way.
The course begins with a non-binding introductory session, during which the method is explained step by step using a presentation. This meeting provides time to explain the approach, answer questions, and explore together what the method could mean for you.
This is followed by a course consisting of eight private sessions. These can take place either online or in person. During this phase, you will gradually learn how to observe, record, and interpret your cycle according to the FertilityCare method.
There is a strong focus on personal guidance, ensuring that the method fits well into your daily life.
As the course progresses, the content is further deepened and adapted to your personal situation — for example, in cases of a desire to conceive, cycle-related symptoms, breastfeeding, or the transition into perimenopause.
The course is not a standalone program, but part of a broader medical-diagnostic approach. It serves as both a foundation for understanding your cycle and a starting point for further care, where medical treatment and personal guidance are closely aligned.
To get started, you can contact one of the FertilityCare instructors for an introductory meeting.
