What Is Anovular Menstruation?
When an egg (ovum) does not come out of the ovary during the menstrual cycle, it is known as anovulatory menstruation. For a pregnancy to occur, an egg is required. A variety of factors can cause anovulation since ovulation involves many hormones. However, a frequent reason for infertility is chronic anovulation.
What Is the Procedure of Ovulation?
The egg or ovum is released from the female ovary; this process is known as ovulation. The menstrual cycle includes ovulation. On average, it takes place on day 14 of a 28-day menstrual cycle. Ovulation is regulated by a number of hormones (gonadotropin-releasing hormone [GnRH], follicle-stimulating hormone [FSH], and luteinizing hormone [LH]). The egg starts its five-day trip through the fallopian tube after ovulation to reach the uterus. The body produces more progesterone, which aids in preparing the uterine lining for pregnancy as the egg passes through the fallopian tube.
The release of an egg triggers progesterone production in a typical cycle. This hormone aids the body of the women in maintaining regular menstrual cycles. However, a low progesterone level during an anovulatory cycle might cause significant bleeding. A woman could mistake this bleeding for her periods.
What Are the Symptoms of Anovulation?
It is important to understand that getting a period does not indicate ovulation.
Anovulation symptoms and signs might include,
-
Amenorrhea (Lack of Periods)- Anovulation may be indicated by missing one or more periods without being pregnant.
-
Irregular Periods- A period is deemed irregular if the interval between periods is unpredictable. Normally, the length of a menstrual period cycle can vary by a few days, although it typically lasts 28 days.
-
Lack of Cervical Mucus- Cervical mucus is the type of vaginal discharge that is most prevalent just before and during ovulation. Typically, it resembles uncooked egg whites. If this discharge is absent, it might be due to anovulation.
-
Abnormal Periods- Heavy menstruation lasts longer than seven days and results in more than 80 mL of blood loss per period. A light period is defined as less than 20 mL of blood loss per period.
-
Irregular Basal Body Temperature- Body temperature during rest is referred to as basal body temperature. It is often taken after waking up and before engaging in any kind of physical activity. The basal body temperature may rise slightly during ovulation.
Who Is at Risk of Anovulation?
The two age groups with the highest prevalence of menstrual cycles without ovulation are,
-
Girls Who Have Just Started Their Period- A girl is more likely to have anovulatory cycles the year after her menarche, which is the start of her first period.
-
Women Approaching Menopause- Hormone alterations are more likely to occur in women between the ages of 40 and 50. Anovulatory cycles could result from this hormonal imbalance.
The bodies of women in both age groups are undergoing numerous changes. Anovulatory cycles might start when hormone levels suddenly alter.
Some other factors increasing the risk for anovulation are as follows,
-
Excessive exercise patterns.
-
Poor food habits.
-
High amounts of stress.
-
Improper body weight.
What Are the Causes of Anovulation?
Anovulation is mainly caused by an imbalance of one or more hormones, particularly those involved in ovulation.
The following hormonal disorders and circumstances can bring on anovulation,
-
Hyperandrogenism (High Androgen Levels)- Hyperandrogenism may result from the following conditions-
-
Obesity.
-
Polycystic ovary syndrome (PCOS).
-
Pituitary gland disorders (Cushing's syndrome or acromegaly).
-
Adrenal gland issues (congenital adrenal hyperplasia or androgen-producing tumors).
-
Medications like anabolic steroids.
-
-
Hypogonadotropic Hypogonadism (Pituitary Gland Dysfunction)- The pituitary gland may not release enough LH and FSH for the following reasons and circumstances-
-
Low body mass index (BMI).
-
Sheehan's syndrome (pituitary necrosis leading to postpartum hypopituitarism).
-
Excessive or intense exercise.
-
Damaged pituitary gland.
-
Pituitary gland tumor.
-
-
Hypothyroidism (Low Levels of Thyroid Hormones)- The following conditions and circumstances can result in hypothyroidism-
-
An autoimmune condition- Hashimoto's thyroiditis.
-
Thyroid surgery.
-
Radiation treatment
-
Several drugs, including lithium.
-
-
Hyperprolactinemia (High Levels of Prolactin)- The following conditions and circumstances can result in hyperprolactinemia-
-
Breastfeeding.
-
Prolactinoma- It is a specific kind of pituitary gland tumor.
-
Damage to the pituitary gland.
-
Damage to or illness of thyroid, liver, kidneys, or other organs.
-
A few medicines, including opioids, psychiatric drugs, and treatments for ulcers or high stomach acid.
-
-
Low Levels of Gonadotropin-Releasing Hormone (GnRH)- Anovulation can be brought on by low blood levels of GnRH. Low amounts of GnRH can result from hypothalamic damage.
-
Anorexia.
-
Premature ovarian failure.
-
Stress.
-
Excessive exercise.
-
Medications- Antiepileptic and antipsychotic medications are associated with ovulatory disruption.
How Is Anovular Menstruation Diagnosed?
Having irregular periods is a common sign of anovulation.
Anovulation can be diagnosed with the following tests,
-
Progesterone levels in the blood.
-
Thyroid levels in the blood.
-
Levels of prolactin in the blood.
-
Examination of the pelvic organ by an ultrasound examination.
-
The doctor may order additional testing if patients exhibit symptoms of a particular hormone imbalance disorder because many of the hormone imbalances that lead to anovulation include additional symptoms.
What Is the Treatment for Anovular Menstruation?
The cause of an anovulatory cycle will determine the course of treatment. However, starting with lifestyle changes and hormonal balance adjustments is common.
The following measures can be taken to treat anovulatory menstruation,
-
Lifestyle Changes- The following lifestyle changes can help-
-
If the healthcare professional believes that stress may be contributing to the anovulation. In that case, they will probably advise patients to attempt to reduce their stressors and use stress-reduction methods like meditation, yoga, or deep breathing.
-
Safely manage the weight with the help of a licensed dietitian.
-
Limiting exercise duration and intensity may be advised by a healthcare professional who suspects that these factors are contributing to anovulation.
-
-
Medications to treat underlying conditions like hypothyroidism or hyperandrogenism.
-
Adjusting Current Medications- Antiepileptic and antipsychotic medications are two examples of pharmaceuticals that can lead to anovulation. Never change the prescription regimen or stop taking it without consulting a doctor. Always abide by the directions on any prescription drug.
-
Human Chorionic Gonadotropin (hCG) Injection- The ovary releases an egg as a result of this hormone. It can be administered in a synthetic form to assist in treating anovulation.
-
Gonadotropin-Releasing Hormone (GnRH) Agonists and Antagonists Injections- It aids in regulating the production of luteinizing hormone (LH), which is essential for ovulation.
-
Follicle-Stimulating Hormone (FSH) Injection- FSH encourages egg release from the ovary.
-
Clomiphene Citrate (CC)- This medicine aids in resolving ovulatory abnormalities.
If lifestyle modifications, medication, or both are unsuccessful in treating the anovulation, there are still methods people might be able to get pregnant if fertility and pregnancy are their goals. There are options like intrauterine insemination (IUI) or in vitro fertilization (IVF).
Conclusion:
An anovulatory cycle often referred to as anovulation, refers to a menstrual cycle in which the release of an egg or ovum from the ovaries does not occur. A prevalent cause of infertility is chronic anovulation, which is anovulation that lasts for a year or longer. Anovulation while attempting to conceive can be stressful and disappointing. The good news is that many anovulation-causing factors are treatable. First, a healthcare physician must be informed if anovulation symptoms are present. Then, they can identify the root cause of anovulation and make therapeutic recommendations.
