In addition to fertile cycles in which ovulation occurs, there are also cycles without ovulation. This also means that your period is not proof of ovulation. Because regardless of whether there are fertile days in the cycle, your period will still occur. As a result, many women are unaware that approximately 11% of all cycles do not include fertile days—that is, they are anovulatory cycles. If this happens only occasionally, there is no cause for concern. If you experience anovulatory cycles more frequently, you should seek advice from your doctor or naturopath.
One Cycle without ovulation (also known as anovulatory or monophasic cycle) is a cycle in which no egg is released—meaning there are no fertile days. Important: A period may still occur, as the uterine lining can build up and shed even without ovulation. In the temperature chart, the typical rise in the second half of the cycle is often missing.
During ovulation, the egg is released from inside the follicle. The female hormonal system causes one follicle to mature in each cycle, from which the egg capable of being fertilized is released. Since this happens rather suddenly as the follicle wall ruptures, the process is referred to as ovulation.
Knowing when ovulation occurs is particularly important for those trying to conceive or using natural family planning methods. Once released, the egg remains fertile for about 12 hours. Therefore, conception is most likely to occur if sperm are already present in the fallopian tubes to meet the egg. Consequently, the two days immediately preceding ovulation offer the highest probability of conceiving.
In a cycle without ovulation, there are no fertile days. The typical rise in temperature does not occur in this case. Other types of cycles without fertile days include the “Birth control pill cycle“and the Cycle with luteal phase deficiency. In the latter case, although there is a slight rise in temperature, the luteal phase is not long enough to be considered a fertile cycle.
If ovulation does not occur in a single cycle—which is generally the exception—the cycle type is determined based on the fertile cycles. Cycles without the typical rise in temperature can therefore occur in all other cycle types. A distinction from the short cycle, regular cycle and long cycle doesn’t make much sense, therefore.
For both cycle types irregular cycle and rhythm-influenced cycle Fluctuations and typical patterns over the course of several cycles are key factors. Depending on the nature of these fluctuations, cycles without ovulation can be a regular part of a woman’s cycle. If the fluctuations affect, for example, the length of the second phase of the cycle, there may be a rise in temperature that does not indicate fertility (see luteal phase deficiency).
The PCOS Regarding cycles without ovulation. Tragically, many women diagnosed with PCOS are also told that they do not ovulate at all. Here, PCOS is mistakenly equated with anovulation (the absence of ovulation). Fortunately, this is not the case. While cycles without ovulation do occur more frequently with PCOS, this does not mean that ovulation never takes place! If you are told that you do not ovulate, do not let that discourage you. Only a medical cycle tracker like OvulaRing can tell you with a high degree of certainty whether you are ovulating and have fertile days or not.

The following plays a special role among the cycle types: PCOS compared to a period without ovulation. Tragically, many women diagnosed with PCOS are often told that they do not ovulate at all. In this context, PCOS is mistakenly equated with a period without a cycle (anovulation). Fortunately, however, this is not the case.
While cycles without ovulation are more common with PCOS, that doesn’t mean you never ovulate! If you’re told that you’re not ovulating, don’t let that discourage you. Only a medical cycle tracker like OvulaRing can tell you with a high degree of certainty whether you’re Ovulation and Fertile Days You do, or you don’t.

Even a regular menstrual cycle is not proof that ovulation is occurring. The bleeding indicates the shedding of the uterine lining, which is why it can also be referred to as withdrawal bleeding. Cyclical hormonal changes in the body are fundamental to the interplay between ovulation and menstrual bleeding.
However, it is possible that while these hormonal changes do not trigger ovulation, they are sufficient to cause changes in the uterine lining.
OvulaRing detects ovulation with over 99% accuracy and can help you determine whether you ovulate regularly and, if so, when. Your cycle is tracked automatically and completely unobtrusively. This makes it possible to detect even minor fluctuations.
OvulaRing has been tested in independent clinical studies for all cycle types and is therefore able to provide accurate insights into your cycle health, even with extremely short cycles.
The menstrual cycle is an indicator of physical health. The absence of ovulation is a sign of a disruption in the menstrual cycle. This disruption may be caused directly by a disturbance in the regulatory cycle or indirectly by other physical factors that affect the regulatory system.
Anovulatory cycles are characterized by the absence of ovulation. Since they do not show a rise in temperature during the second half of the cycle, they are referred to as monophasic (single-phase) cycles. In these cycles, the core body temperature remains at a similar level to that in the first phase of the cycle. Nevertheless, menstrual bleeding often occurs at the usual time. Women do not notice the absence of ovulation. This means that regular menstrual bleeding is not, as most women often assume, synonymous with a healthy ovulatory cycle!
In an anovulatory cycle, although enough follicles mature in the ovaries and produce sufficient estrogen, ovulation—and thus the fertile window—does not occur. The signal that triggers ovulation is missing, so the mature egg cannot be released from the follicle, and the corpus luteum does not form to produce progesterone.
There are many reasons why a woman may not ovulate. For one thing, the regulatory pathways involving the diencephalon, pituitary gland, and ovaries may be disrupted. In addition, certain health factors can also negatively affect this regulatory system. Any excessive physical or emotional stressors can disrupt the necessary balance in this cycle. Possible causes include, for example, prolonged physical stress, excessive exercise, high psychological stress, an unhealthy lifestyle, obesity, but also excessive weight loss (such as in cases of anorexia), a significant hormonal imbalance, or early onset of menopause.
Anovulatory cycles often occur during puberty after the first menstrual period (menarche), after pregnancy, before menopause, in cases of PCOS, due to a hormonal imbalance involving thyroid-stimulating hormone (TSH) and prolactin, or after stopping the birth control pill. However: An isolated monophasic cycle is not yet a cause for concern. Only when anovulatory cycles occur frequently should you discuss this with your gynecologist. By the way: OvulaRing users know their cycle precisely and can check at any time whether a healthy cycle with ovulation has resumed after an anovulatory cycle.
Yes! Body temperature reflects the hormonal changes in the female cycle. The release of progesterone, which begins shortly before ovulation, causes your core body temperature to rise by 0.25 to 0.5°C over a period of about 3 to 5 days. A monophasic cycle is recognized by the medical algorithms of the OvulaRing software when
As a result, a user may notice a small, short-lived change in temperature on her cycle chart even though ovulation has not occurred. This happens because the unruptured follicle produces a small amount of progesterone (a condition known as LUF syndrome). Pregnancy would not be possible in such a cycle.
OvulaRing detects ovulation with 99% accuracy when reviewing past data. Conversely, this also means that any monophasic cycle identified is accurate. This allows you to always check precisely whether your cycles are “healthy” or if there might be a cycle irregularity.
If you are already an OvulaRing user, you should inform your gynecologist of your test result. They will conduct further diagnostic tests and try to identify the cause of the irregularity. If the anovulation is caused, for example, by being overweight or underweight, bringing your weight back to a normal range may help restore ovulation. Similarly, a woman may also realize on her own that she is not getting her period due to extreme exercise or high stress levels. Reducing physical activity or engaging in stress-management activities such as yoga or meditation can help her resume ovulation.
Lifestyle changes alone aren’t always enough to restore ovulation. If you’re trying to conceive and have been experiencing repeated monophasic cycles, your gynecologist will prescribe medication to induce ovulation. Treatment options include clomiphene, letrozole, or FSH injections.
Clomiphene is a medication (anti-estrogen) that is often prescribed to induce ovulation. Treatment typically begins on the third to fifth day after the start of the period. Clomiphene is taken daily (1–3 tablets) for the following five days. Once the course of treatment is complete, ovulation usually occurs about one week later. Clomiphene “tricks the body” into thinking there is too little estrogen. The pituitary gland attempts to compensate for this deficiency by increasing production of follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These hormones stimulate ovarian function, thereby ensuring follicle maturation and ovulation. LH is the hormone that triggers ovulation. In the treatment of anovulation, an LH or hCG injection is therefore prescribed either alone or, often, in addition to the medication.
By the way, with OvulaRing, you can accurately track whether medication has been effective and whether or when ovulation has occurred.
No! Many women assume that a regular period means ovulation has occurred. However, this isn’t always the case, because hormonal changes can be enough to alter the uterine lining—even without ovulation—which then leads to regular bleeding. To be sure that you are ovulating and that your cycles are healthy, you can use OvulaRing, even if you have very long or very irregular cycles. This reliably detects anovulation. To help you keep track, you should always record the days on which you had sexual intercourse in the cycle diary integrated into the OvulaRing software. This way, you’ll know both in real time and in retrospect when and whether a pregnancy would have been possible.
Yes. Bleeding at the end of the menstrual cycle is not definitive proof of ovulation. The uterine lining can thicken and shed even without ovulation—in which case bleeding still occurs (often described as withdrawal bleeding or hormonal withdrawal bleeding).
Measurement data is more reliable than calendar-based rules. Typically, the temperature curve does not show a steady rise in temperature during the second half of the cycle (monophasic pattern). Individual “spikes” may occur, but they do not necessarily indicate ovulation—the pattern over several days is what matters.
Occasional anovulatory cycles can occur even in otherwise healthy women and are not necessarily a cause for concern. However, if cycles without ovulation occur more frequently or a pattern emerges, it is advisable to consult a doctor (e.g., to investigate hormonal factors, stress, thyroid function, prolactin levels, PCOS, etc.).
Common triggers include stress, intense physical exertion (e.g., very high-intensity exercise), weight changes (underweight or overweight), medical conditions or hormonal imbalances (e.g., thyroid/TSH, prolactin), PCOS, the postpartum period, puberty, or the premenopausal phase. Often, it is a combination of several factors that disrupts the menstrual cycle.
Yes. Since ovulation is usually associated with a rise in progesterone levels and a rise in body temperature, an anovulatory cycle can be identified by the absence or irregular pattern of this rise. This helps you determine whether you had any fertile days at all (e.g., if you’re trying to conceive) and whether there are signs of a cycle disorder over several cycles, which you can then discuss specifically with your doctor.

Once your period has ended, OvulaRing is inserted into the vagina like a tampon. Regardless of external factors, it automatically records your temperature every 5 minutes inside your body, tracking your individual fertility patterns.
The data is transferred to the web-based analysis software using a USB reader. You can access it anytime, anywhere through your personal account. The security of your data is our top priority.
The OvulaRing app uses medical algorithms to analyze your cycle. In addition to cycle length, ovulation day, and the length of each phase of your cycle, it shows you your daily probability of conception*** and an ovulation forecast**** for the following month.
Is your cycle super short, extremely long, or even very irregular? OvulaRing tracks your personal cycle, no matter what Cycle type you are. The OvulaRing method works for all types of cycles. This has also been confirmed in three medical studies covering a wide range of cycle types.
With traditional basal body temperature tracking, you don’t measure your temperature continuously, but only once a day. To analyze your personal cycle even more accurately, however, OvulaRing measures your temperature around the clock and records 288 data points every day. This provides much more information for pinpointing your fertile days. OvulaRing also recognizes your very own cycle pattern and provides you with accurate results.
OvulaRing is just as easy to use and feels even less noticeable than a tampon. When you wear OvulaRing, you can go about your daily life just as you always have. For example, you can exercise or go to the sauna. You can still have sex and enjoy your life. The automatic measurement inside your body always provides accurate results. It doesn’t matter what your daily routine looks like—the measurement works regardless.
OvulaRing can reliably tell you whether you’re ovulating. It also helps you determine whether your cycles are healthy. The app starts by learning your unique cycle patterns in detail. Once your cycle patterns have been identified, it provides you with a daily update on your fertility status. How OvulaRing Works.
OvulaRing was developed by renowned gynecologists at the University Women’s Hospital in Leipzig. As a result, the method is based on 40 years of experience and scientific research. In addition, OvulaRing is patented and approved as a medical device. Furthermore, the accuracy of OvulaRing has been demonstrated in several medical studies.
On the one hand, OvulaRing works entirely without hormones. On the other hand, the ring is also free of plasticizers and side effects. It doesn’t put any strain on your body! In addition, OvulaRing is very comfortable to wear and is as easy to use as a tampon. The material’s excellent tolerability has been confirmed in several medical studies.
