Secondary Hypogonadism due to Pituitary Macroadenoma: A Personal Account
I have been diagnosed with a prolactin-secreting pituitary macroadenoma, also known as a prolactinoma. My growth hormone levels are nearly non-existent, and I discovered the presence of this macroadenoma unintentionally. For the past decade, I have experienced symptoms indicative of low testosterone, which include an almost non-existent mustache, a sparse beard, and a shorter stature compared to my father and brothers, who are tall. It feels as though I didn’t fully reach puberty, and I have very little body hair overall. Moreover, I have been struggling to lose fat, with my abdomen steadily increasing in size. My physician has suggested cabergoline as a treatment for my prolactinoma, but I have seen no improvements after about four months of this medication. While cabergoline may help lower prolactin levels, I am concerned about how to boost testosterone. My MRI suggests that my pituitary gland is suffering significant damage. The MRI results indicate a sizable, well-defined solid mass located in the sellar region, which is causing it to widen. The pituitary gland or stalk is not distinctly identifiable. The lesion shows similar intensity on T1 and T2/FLAIR sequences and exhibits uniform enhancement after contrast, with no signs of diffusion restriction or blooming on SWI. The dimensions are approximately 2.4 x 3.1 x 3.9 cm (anterior-posterior x transverse x craniocaudal). It extends superiorly into the suprasellar area, resulting in some compression of the chiasmatic cistern and a slight upward displacement of the optic chiasm. Below, the mass is eroding the floor of the hypophyseal fossa, extending into the clivus. On the right side, it is adjacent to the cavernous segment of the right internal carotid artery (ICA), partially encasing the clinoid segment of the right ICA. It also reaches above the intra-cavernous ICA into the right superior cavernous sinus compartment, causing a bulging effect. This mass is categorized as Knosp grade 3A. On the left side, the lesion is in contact with the cavernous segment of the left ICA, but does not appear to extend into the left cavernous sinus.

I understand that dealing with a prolactin-secreting pituitary macroadenoma, particularly when it affects your hormonal balance, can be challenging and concerning. Your symptoms, including low testosterone levels and physical changes suggestive of incomplete puberty, merit careful monitoring and management. Here’s a summary of key points and specific steps you can consider to address these concerns.
Key Points:
- You have a prolactin-secreting pituitary macroadenoma causing secondary hypogonadism, evident through low testosterone levels and symptoms related to insufficient hormonal production.
- Cabergoline is commonly prescribed to reduce prolactin levels, but if you're not seeing improvements, it's essential to reevaluate your treatment plan.
- Your MRI results indicate significant involvement of the pituitary gland, which may impact your hormonal function and overall health.
Explanation:
- Prolactinomas often impact other hormone levels due to pressure on the pituitary gland. This can lead to hormonal deficiencies such as low testosterone.
- Low testosterone levels can cause various symptoms, including changes in body composition, sexual health concerns, and feelings of low energy.
- The size and location of the macroadenoma can complicate treatment strategies and may require additional evaluation to ensure all aspects of your health are being addressed.
Next Steps:
-
Consult with Your Endocrinologist:
- It’s crucial to have an ongoing dialogue with your healthcare team about the lack of improvements with cabergoline. They may adjust the dosage or consider alternative medications.
- Discuss the possibility of testosterone replacement therapy (TRT). Depending on your individual circumstances, your doctor may recommend blood tests to confirm testosterone deficiency before starting TRT.
-
Consider Lifestyle Modifications:
- Focus on a balanced diet rich in lean proteins, healthy fats, and whole grains to support general health and energy levels.
- Regular physical activity, including strength training, can help manage body fat and improve overall health, which may help counteract some effects of low testosterone.
-
Monitor Symptoms Closely:
- Keep a record of your symptoms, mood changes, energy levels, and any effects you experience from the current treatment. This information will be valuable during follow-up appointments.
-
Discuss Neurological Follow-Up:
- Given the extent of the macroadenoma and its effect on nearby structures, ensure there’s an ongoing assessment of neurological symptoms. Regular follow-up imaging may be necessary to monitor any changes in the tumor.
Reassurance:
It’s entirely valid to feel concerned about the symptoms you are experiencing, and seeking clarity and effective treatment is important. With the right approach and support, there are options to manage your condition and improve quality of life. Stay engaged with your healthcare team, and don’t hesitate to voice your concerns or seek additional opinions if needed. Let me know if you have further questions or need more specific information!

Experiencing Clear Fluid from Ear with No Discomfort: Should I Wait for My Appointment?
I am a healthy 57-year-old female, weighing 120 pounds and standing 5 feet 5 inches tall. My daily medications include 100 mg of Losartan for effectively managed high blood pressure, 200 mg of Lyrica taken twice daily for post-herpetic neuralgia, 100 mg of Synthroid following treatment for thyroid cancer, and a combination hormone replacement therapy patch. Additionally, I take Zyrtec and Flonase every day to combat allergies. Since October, I have been dealing with persistent tinnitus in my right ear, accompanied by some pressure and a muffled sensation. Recently, I've noticed that when I speak, it feels akin to the sensation I experience when my ears clear during a flight after chewing gum—my voice sounds amplified in my head. I've scheduled an appointment with a physician's assistant in an ear, nose, and throat (ENT) office for the end of March due to my worries about the tinnitus and any potential hearing impairment. Yesterday, I noticed that my ear emitted a clear fluid. Thankfully, there was no associated pain. The fluid was somewhat thicker than water, completely odorless—unlike the unpleasant discharge I recall from my daughter's ear infections—and there was no sign of blood. Could this indicate a perforated eardrum? I suspect this might be the case, but can this occur without an underlying infection? Should I seek attention sooner than my appointment in March? I would prefer to avoid urgent care during flu season; however, if this situation is serious, I am prepared to take precautions and visit.
Assessing My Health Concerns: How Anxious Should I Be?
I’m a 32-year-old woman, weighing 124 pounds and standing at 5 feet 6 inches tall. For over a year, I have been experiencing bright red rectal bleeding. Initially, I attributed this issue to hemorrhoids that developed during my pregnancy two years ago. The bleeding occurs with most of my bowel movements, sometimes happens without one, and on a few occasions, has been enough to stain the toilet bowl significantly. The color of the blood is typically darker than what I observe during a hemorrhoid flare-up. There is a notable family history of bowel cancer on both sides; one family member was diagnosed at age 45, and another at 60. In the past six months, I have encountered several episodes of severe abdominal pain—3 to 4 instances—intense enough to consider a trip to the emergency room. However, the pain usually subsides within about an hour. It’s unusual for me to experience such acute pain, given my high tolerance for discomfort; for example, I once played rugby shortly after dislocating and fracturing my finger. Recently, I mustered the courage to consult with my doctor, who recommended a FIT test, which returned a positive result (30.1). Additionally, I underwent a complete blood test, and aside from having low ferritin levels (7 µg/L), all other results were normal. I have since been referred for a colonoscopy on a two-week waiting list to rule out any possible bowel cancer. Given these circumstances, how concerned should I be? Thank you for your input.
Understanding Possible Seizure Triggers and Recurrence Risks
Health Background: I am a 21-year-old female, standing at 169 cm and weighing 65 kg. Over the past three years, I have been using oral contraceptives. As of this morning, I started taking 25 mcg of levothyroxine along with a weekly vitamin D supplement of 0.266 mg. Recently, I was diagnosed with hypothyroidism and found to have a vitamin D deficiency that I suspect has existed for the last three years. I do not consume alcohol or smoke, and I can confirm I am not pregnant. Two years ago, I experienced a mild concussion. I currently reside in Spain. A couple of months back, in mid-December, I blacked out twice. The second occurrence took place while I was at the doctor’s office after seeking urgent medical care for the initial incident. Following the second episode, I underwent a CT scan and an EKG, both of which returned normal results. Further tests, as directed by my physician, revealed a critical vitamin D deficiency and hypothyroidism; however, he expressed doubt that either of these conditions led to my loss of consciousness. I was then referred to a neurologist, and I am presently awaiting an appointment. Although the waiting period is lengthy, my doctor indicated that I should receive priority for scheduling, although the exact timeframe remains uncertain. The referral document summarized my events, labeling the second episode (which the physician witnessed) as a potential seizure devoid of tonic-clonic movements—a revelation that took me by surprise. After regaining consciousness, I felt extremely disoriented and terrified, struggling to process what was happening. I have no prior history of seizures, epilepsy, or any related conditions, and there is no known family history of these issues. If this indeed was a seizure, what might have triggered it? Additionally, what is the likelihood of experiencing another one? Since that time, I have not had any further incidents, but I have experienced moments where I felt a sense of impending doom, which I managed to overcome. I intend to wait for the neurologist's evaluation, but the uncertainty surrounding a possible neurological condition is quite distressing. Thank you for any insight you can provide!
Understanding EEG Results for My 22-Month-Old Son: Insights Needed
Could someone help clarify this for me? My son, who is just 22 months old, hasn’t started walking yet, becomes tired easily, and has been experiencing behavioral outbursts. He had a febrile seizure in February 2025, followed by another unexplained seizure in April 2025, which led us to consult a neurologist. Since he was 3 months old, he has been receiving therapy from a physical therapist for torticollis. At birth, he spent five days in the NICU due to issues with meconium aspiration. A recent MRI showed normal results, and he also had a follow-up EEG after one conducted in July 2025. The results from this recent EEG were abnormal for a pediatric patient in awake, drowsy, and sleeping states. Notably, there were brief episodes of left frontotemporal delta slowing, which occurred mainly when he was awake and drowsy. There were no signs of epileptiform activity detected. In contrast, the EEG performed back on July 3, 2025, was deemed normal for both awake and drowsy states, again with no evidence of epileptiform irregularities, although it did not capture any sleep data. This examination was prompted by the child's existing history of febrile seizures. Importantly, he is not currently on any anti-seizure medications. The EEG procedure used standard electrode placements per the 10-20 system, conducted a single-lead EKG, and included continuous video monitoring. During the analysis, the background activity was symmetric, indicating some anterior-posterior (AP) organization, with a dominant rhythm of 50-80 microvolts at 7 Hz. His drowsy state was marked by a reduced amount of eye blink activity, less breathing motion interference, and a generalized slowing in theta/delta frequencies. Stage II sleep exhibited spindles and vertex waves patterns. Additionally, there were intermittent bursts of 250-300 microvolts in the left frontotemporal region with semi-rhythmic activity of 2-4 Hz, mostly observed during wakefulness and drowsiness. No definitive epileptiform discharge was noted. Photic stimulation during the test did not elicit a strong response, and hyperventilation was not conducted during this session.
Understanding Atrial Fibrillation and Thyroid Issues: Variability in Cardioversion Decisions
Hello everyone, I’m reaching out for guidance regarding my mother’s current health situation, and I’d greatly appreciate any shared experiences or thoughts. **My mother's background:** - **Age**: 55 years - **Weight**: Recently dropped to 116 kg from 118 kg in just two days, likely due to diuretics. - **Health history**: Previously an underactive thyroid, undiagnosed and untreated, now presenting as overactive. - **Medications**: Currently taking thyroid medication and a beta-blocker (Rapiblock). **Current health status:** My mother has been hospitalized since Tuesday, experiencing **atrial fibrillation with heart rates exceeding 200** beats per minute due to her thyroid's hyperactivity. - The plan for cardioversion was initially settled on Tuesday. However, the following day, the medical team advised postponing it until her thyroid levels could be stabilized, believing that her heart rate would return to normal once her thyroid condition was managed. - Her **obesity** precludes her from undergoing a transthoracic echocardiogram, and due to her thyroid concerns, she cannot handle contrast dye (this has been a consistent issue for over four years). Therefore, the only feasible option was a **transesophageal echocardiogram (TEE)**, which has yet to be performed. - She has been prescribed various medications including beta-blockers and thyroid treatments in the past. - On Friday, a doctor proposed proceeding with cardioversion; however, the attending senior physician objected. - Today (Saturday), another clinician has expressed a desire to move forward with cardioversion, having initiated a new medication, as the senior physician is unavailable. - **Communication has been unclear**, as we were notified of developments by a nurse rather than the physician in charge, causing confusion and anxiety. - Currently, only a **chest X-ray** is scheduled, and the TEE remains unaddressed. **My inquiries are as follows:** 1. Is it common for medical professionals to have varying opinions and frequently revise medication or treatment plans like cardioversion? 2. Is it safe to conduct cardioversion in the absence of a TEE? I presumed that this was a standard procedure to exclude the presence of blood clots. 3. Is it usual practice to have only a chest X-ray prior to moving ahead with cardioversion? 4. How typical is it for patients or their families to not be directly informed about treatment changes and learn about them through nursing staff instead? I recognize that this cannot substitute for professional medical advice. I’m simply trying to discern whether these circumstances are typical or if we should express our concerns more assertively with the healthcare facility. Thank you for your insights!
