Infertility is an intricate medical condition with several underlying factors. One hormone that does not get consideration in terms of fertility problems is prolactin. Prolactin, while necessary for breastfeeding, has negative effects on both male and female fertility when present in excess. If you have not been able to achieve pregnancy, increased prolactin levels might be a reason. This article will discuss the impacts of high levels of prolactin on infertility and how it can alter the chances of conception.

What is Prolactin?

Definition of Prolactin

Prolactin is a hormone secreted from the anterior pituitary, a gland located on the base of the brain. Its most important physiological function is to regulate milk secretion in women after they deliver the baby. Besides breastfeeding, Prolactin impacts metabolism, the immune system, and reproduction, and other important functions.

Reproductive Functions of Prolactin

Prolactin encourages lactation and has other functions like regulating the menstrual cycle as well as assisting in mammary gland development during pregnancy. Prolactin also participates in the pulsatile release of other hormones responsible for ovulation and is therefore important for reproduction. However, there is a fertility problem when there is an imbalance in prolactin levels.

Causes of High Levels of Prolactin

Common Causes of High Prolactin

Prolactin elevation (Hyperprolactinaemia) can result from several causes. The following are some of the most commonly encountered causes:

Pituitary Tumors (Prolactinomas): These benign tumors are capable of causing an increased secretion of prolactin.

Hypothyroidism: An underactive thyroid gland tends to increase the concentration of prolactin.

Medications: Certain medications, especially those affecting dopamine like some classes of antidepressants, tend to increase the concentration of prolactin.

Stress: There is increased secretion of prolactin associated with both physical and emotional stress.

Pregnancy and Lactation: Prolactin secretion is Rampant during pregnancy and nursing.

Other Hormonal Imbalance Related to Prolactin

Prolactin can also be caused by an imbalance in other hormones such as estrogen or dopamine. Such imbalance disturbs the normal fertility mechanisms in the body and makes conception difficult.

Link Between High Prolactin and Infertility

How Increased Prolactin Affects Ovulation

Elevated levels of prolactin cause dysfunction during the release of ova from the ovaries (ovulation). Prolactin represses the secretion of gonadotropin releasing hormone (GnRH) which is required for trophic hormones like luteinising hormone (LH) and follicle stimulating hormone (FSH). LH and FSH need to be released in appropriate quantities for the ovaries to respond to exogenous signals to release an ova; otherwise, fertility will not be achievable.

Effects on Menstrual Cycle and Fertility

Having an abnormal menstrual cycle is one of the visible consequences of elevated prolactin levels. Women with prolactin secreting adenomas can have irregular menstruation or even amenorrhea. These make it impossible to estimate the timing of ovulation and thus, become pregnant.

Signs and Symptoms of Increased Prolactin

Physiological Signs and Symptoms to Be Aware Of

Alongside infertility, hyperprolactinemia may lead to the following symptoms:

• Irregular or absent menstrual periods
• Lactation in the absence of pregnancy (galactorrhoea)
• Headaches and vision field defects (in case of pituitary adenomas)
• Mastalgias (breast pain)
• Decreased sexual desire

Consult your clinician for any of the symptoms mentioned above.

How High Prolactin Impacts Pregnancy

Roles Of Prolactin During Conception

Prolactin can be useful for successful conception. However, like most things in life, balance is essential. Increasing prolactin tends to inhibit some critical steps in reproductive health like ovulation which in turn will lower fertility rates hence it makes conception more difficult.

Changes In Hormone Levels And Early Miscarriages

Temporarily elevated levels of prolactin help prepare the body for proper lactation during the earliest stages of pregnancy. Nonetheless, excessive levels of prolactin can lead to hormonal imbalance resulting in miscarriage or make it far more challenging to carry the baby to full term.

Diagnosing and Treating High Prolactin

Diagnosis via Clinical and Lab Examination

High prolactin,, like many other medical conditions, can be diagnosed with a blood test. In this case, measuring the concentration of prolactin hormone circulating within the body’s system. When the level of prolactin is high, then further tests to find out the reason for the increased prolactin levels is done like imaging for pituitary tumours.

Protocols For Evaluation

High prolactin concentration can also be linked to prolactinoma and other structural changes of the pituitary gland that can be visualized by MRI or CT scans and therefore these imaging modalities become valuable diagnostic tools.

High Prolactin Treatment Options

Lower Prolactin Treatment

The most frequent approach in managing elevated prolactin levels involves the initiation of dopamine agonists, including bromocriptine or cabergoline. These medications lower the levels of prolactin by activating dopamine receptors which decrease its production.

Other Treatment Approaches

In some situations it may become necessary to surgically remove the pituitary tumours whichat contribute to the raised levels of prolactin. Other forms of treatment also include the use of radiation therapy, although it is mostly used in cases where other forms of treatment have failed.

Optimizing Prolactin Levels to Enhance Fertility

Hormonal Balance Assisted by Lifestyle Changes

Improving sleep, managing stress, and achieving a healthy body weight can also aid in controlling prolactin levels. Supporting hormonal balance also requires eating a well-balanced diet which provides the body with all necessary micronutrients.

Exercise and Diet Recommendations

Adopting an active lifestyle along with a diet consisting of lean meats, healthy fats, essential fatty acids, as well as sufficient amounts of vitamins will aid in achieving hormonal balance and improve the functionality of the reproductive system.

Is High Prolactin Level Preventable?

Actions Aimed At Preventing Imbalance of Prolactin Hormone

While high levels of prolactin cannot always be prevented, taking care of one’s well-being, avoiding anxiety, and treating some chronic conditions such as those with the thyroid gland can mitigate the chances significantly.

Importance Of Regular Checkups

Regular checkups are critical in managing hormonal disorders. If you are planning to get pregnant, visiting a specialist would be helpful in making sure that your hormonal levels are at best.

High Prolactin And Male Infertility

How High Prolactin Affects Male Fertility

Prolactin is a hormone women are known to suffer from, but it’s one of the factors that can cause infertility in men too. As for men, high prolactin can lower testosterone secretion which can result in low-volume sperm production, erectile impotency, and decreased sexual desire.

Treatment For Men With High Prolactin

Therapy for men parallels that of women. In men, it is often treated with bromocriptine or cabergoline, which decreases prolactin similarly as in women.

Risks Of Untreated High Prolactin

Long-Term Effects On Fertility

Without treatment, high levels of prolactin may result in not being able to have children long-term. It may lead to irreparable damage to the reproductive organs, increasing the difficulty to conceive.

Other Health Complications Linked To High Prolactin

Elevated prolactin above the average level for an extended amount of time may also result in other health problems like osteoporosis and reduction of bone density, or vision problems caused by pituitary tumors.

When to Visit the Doctor?

Recognizing Symptoms of Elevated Prolactin Levels

It’s pivotal to consult a physician if you notice irregular menstruation cycles, lactating without a cause, and similar symptoms as it may signify high prolactin levels. An early diagnosis will enhance your chances for successful treatment and conception.

Why Seeking Medical Help Early Matters

The earlier you seek medical help the better it is, especially when you want to avoid complications. An early medical intervention has the potential to improve fertility outcomes.

Final Thoughts

Having high prolactin levels can significantly alter fertility and pregnancy potential, but diagnosing and properly treating the condition can assist in managing it, thereby, improving chances of conception. Seek medical advice urgently if you notice symptoms of infertility.
