Menstrual cycle without ovulation

Menstrual cycle types


It is normal not to ovulate all the time

In addition to fertile cycles in which ovulation occurs, there are also menstrual cycles without ovulation. This also means that your menstruation is not proof of ovulation. Because regardless of whether there are fertile days in the cycle, the period still occurs. This means that many women are not aware that about 11% of all cycles have no fertile days, i.e. cycles without ovulation. If this only happens once in a while, there is no reason to worry. If you have frequent cycles without ovulation, you should seek advice from your doctor or alternative practitioner.

Classification and demarcation of other cycle types

In a cycle without ovulation there are no fertile days. The typical rise in temperature does not occur. Other types of cycles without fertile days are the “birth control pill cycle” and the cycle with luteal weakness. In the latter case there is a certain temperature rise, but the luteal phase is not long enough for this to be called a fertile cycle.

If ovulation does not occur in a single cycle and this is rather the exception, the cycle type is determined according to the fertile cycles. Cycles without the typical temperature rise can therefore occur in all other cycle types. A distinction between the short cycle, regular menstrual cycle and long menstrual cycle is therefore not very meaningful.

For the two cycle types irregular cycle and rhythm-influenced cycle, fluctuations and typical rhythms over several cycles are decisive. Depending on how pronounced they are, cycles without ovulation can be an integral part of a woman’s cycle. If the fluctuations affect the length of the 2nd cycle phase, for example, then there may be a temperature increase that is not fertile (cf. luteal insufficiency).

PCO syndrome seems to have a special relationship to cycles without ovulation. Tragically, many women diagnosed with PCOS are also told that they have no ovulation at all. Here, PCO syndrome is mistakenly equated with annovulation (no ovulation). Fortunately, this does not correspond to reality. In PCO syndrome, cycles without ovulation do occur more often. But this does not mean that ovulation never takes place! If you are told that you are not ovulating, do not let this encourage you. Only a medical cycle tracker like OvulaRing can tell you with a high degree of certainty whether or not you are ovulating and having fertile days.

Brief overview:

What are cycles without ovulation characterised by?

Correctly recognise cycles without ovulation

Menstruation is not proof of ovulation

Regular menstruation also no proof that ovulation is taking place. The bleeding shows the rejection of the uterine lining, which is why it can also be called hormone withdrawal bleeding. Fundamental to the interaction of ovulation and menstrual bleeding are cyclical hormonal changes in the body.

However, it is possible that the hormonal changes do not trigger ovulation, but are sufficient for the change in the uterine lining.

OvulaRing helps you to accurately recognise your fertile days

OvulaRing detects ovulation with a certainty of over 99% and can give you clarity about whether you ovulate regularly and if so, at what time. Your cycle is measured automatically and completely unnoticed. This makes it possible to detect even small fluctuations.

OvulaRing has been tested in independent clinical studies for all cycle types and is therefore able to make precise statements about your menstrual cycle health even with extremely short cycles.

Why am I not ovulating?

The cycle is an indicator of physical health. A lack of ovulation is the expression of a disturbed cycle regulation. This disturbance can be caused directly by an impairment of the regulatory circuit or indirectly by other physical factors that have an effect on the regulatory system.

How can I recognise cycles without ovulation?

Anovulatory cycles are characterised by the absence of ovulation. As there is no temperature rise in the second half of the cycle, they are called monophasic (single-phase) menstrual cycles. In these cycles, the core body temperature remains at a similar temperature level as in the first phase of the cycle. Nevertheless, menstrual periods often occur at the usual time. Women do not notice that ovulation has not occurred. This means that regular menstrual bleeding is not, as most women often assume, synonymous with a healthy ovulatory cycle!

How do anovulatory cycles occur?

In the case of an anovulatory cycle, enough follicles mature in the ovaries and produce enough oestrogens, but ovulation and thus the fertile days do not occur. The impulse that triggers ovulation is missing, so that the mature egg cannot detach from the follicle and there is no formation of the corpus luteum with progesterone production.

What are the most common reasons for cycles without ovulation?

There are many reasons why ovulation does not occur in women. For one thing, the regulatory levels of the diencephalon, pituitary gland and ovary may be disturbed. In addition, some health factors can also negatively influence the regulatory system. All excessive physical/physical and psychological/emotional stress factors can throw the necessary balance out of rhythm. For example, prolonged physical stress situations, too much sport, high psychological stress, an unhealthy lifestyle, obesity, but also excessive weight reduction such as in anorexia, a pronounced hormonal disorder or a premature onset of the menopause can be mentioned as possible causes.

Anovulatory cycles also frequently occur during puberty after the first menstrual period (menarche), after pregnancy, before the menopause, with PCO syndrome, with a hormonal imbalance of thyroid-stimulating hormone (TSH) and prolactin or after stopping the contraceptive pill. However, an isolated monophasic cycle is not yet a cause for concern. Only if the anovulatory cycles occur more frequently should you talk to your gynaecologist about it. By the way: OvulaRing users know their cycle exactly and can check at any time whether a healthy cycle with ovulation has returned after an anovulatory cycle.

Does the OvulaRing app also recognise monophasic cycles?

Yes, body temperature reflects the hormones in the female cycle. The progesterone release that 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 detected by the medical algorithms of the OvulaRing software when

For example, the user may notice a small and short-term temperature change in the cycle curve without ovulation having occurred. This is due to the fact that the non-ovulated follicle produces a small amount of progesterone (so-called LUF syndrome). Pregnancy would not be possible in such a cycle.

OvulaRing detects ovulation in retrospective observation with a certainty of 99%. Conversely, this also means that a monophasic menstrual cycle is correct. This means that you can always check exactly whether your cycles are “healthy” or whether there might be a menstrual cycle disorder.

No ovulation - what can I do?

If you are already an OvulaRing user, you should inform your gynaecologist about your test result. They will do further diagnostics and try to find the cause of the disorder. If anovulation is caused by being overweight or underweight, for example, a change in weight to the normal range can help restore ovulation. Analogously, the woman can also find out for herself that she may not be getting periods due to extreme exercise or increased stress levels. Reducing exercise or stress management activities such as yoga or meditation can help her to ovulate again.

How is a lack of ovulation treated?

Lifestyle changes alone are not always enough to induce ovulation again. If you want to have children and have repeated monophasic menstrual cycles, your gynaecologist will prescribe medication for ovulation induction. Clomiphene, letrozole or FSH injections are given as treatment.

Clomiphene is a drug (antiestrogen) that is often given to induce ovulation. Treatment usually starts on the third to fifth day after the onset of the period. Clomiphene is taken (1-3 tablets) daily for the next five days. Once the intake is complete, ovulation usually occurs after about a week. Clomiphene “fools” the body into thinking there is not enough oestrogen. The pituitary gland tries to compensate for this deficiency by producing more follicle-stimulating hormone (FSH) and luteinising hormone (LH). These hormones stimulate ovarian function and thus ensure follicle maturation and ovulation. LH is the hormone that triggers ovulation. In the treatment of anovulation, LH or hCG injections are therefore prescribed alone or often in addition.

By the way, with OvulaRing you can check exactly whether a drug treatment was successful and whether or when ovulation occurred.

Does menstruation mean that ovulation has taken place beforehand?

No! Many women assume that a regular period indicates that ovulation has also taken place. However, this is not always the case, because it is possible that the hormonal changes are sufficient for the uterine lining to change 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 will give you a reliable indication of anovulation. For better orientation, you should always enter the days with successful sexual intercourse in the cycle diary integrated in the OvulaRing software. This way you know when and if a pregnancy would have been possible, both now and in retrospect.
