Ovulation is the process of egg release from one of the two ovaries (1). These eggs help you get pregnant, but some women may not be ovulating despite regular menstrual periods. But how can you get pregnant when you are not ovulating? This post helps you understand it better.
鸡蛋没有得到从卵巢释放是termed anovulation. Also called chronic anovulation, it continues for a year or longer and is a common cause of infertility.根据国家健康研究所blems associated with ovulation account for around 30% of infertility cases(2).
What Causes Anovulation?
Multiple hormones play a role in ovulation. Some of them include gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), and luteinizing hormone (LH). Any imbalance with these hormones can cause problems with ovulation.
Some other causes of anovulation are as follows (3):
1. Obesity
High body weight or BMI (body mass index) can cause a chemical imbalance in the body if there are excess androgens such as testosterone.
2. Stress

Excessive stress can cause an imbalance in the hormones necessary for ovulation.
3. First and last periods
Anovulation can occur at any time during one’smenstrual cycle. However, it is more common when a girl first begins her menstruation or is approaching her menopause. Anovulation during this time may occur due to hormonal imbalance.
4. Low body weight or excessive workout
Excessive exercising or low body weight can negatively impact the woman’s pituitary gland leading to underproduction of LH and FSH.
5. Not consuming enough calories
A lesser bodyweight than usual can cause hormonal imbalance and may lead to issues with ovulation.
6. Hormonal birth control

The hormones in birth control pills prevent one from ovulating (4).
7. Polycystic ovary syndrome (PCOS)
PCOS is a common condition affecting around one in ten women of childbearing age, causing anovulation. Small and painless cysts indicate the syndrome on the ovaries along with acne, or excessive male pattern hair growth, especially around the chin and upper lip.PCOS leadsto an overproduction of male hormones or androgens such as testosterone. With increased androgen levels, the ovarian follicles that contain eggs remain small.
Point to consider8. Abnormalities of TSH or prolactin
The imbalance of either of these hormones can cause issues with ovulation.
9. Hypogonadotropic hypogonadism (HA)
It is a condition in which the ovaries make little or no sex hormones (5) and is characterized by ovulation and reproduction disorders (6).
10. Ovarian insufficiency
It is a condition wherein the ovaries stop functioning before a woman turns forty years and may lead to anovulation (7).

Frequently Asked Questions
1. When does ovulation occur after the anovulatory cycle?
Some women may start ovulating in the subsequent menstrual cycle following an anovulatory cycle. However, others may continue their anovulation for months or years before they resume ovulating (10).
