Impact of Dutasteride on Breast Development

3/23/2025, 10:50:18 PMMale25-34

Age 26, male who identifies as closeted MTF, somewhat overweight, of average height, and Asian descent. Due to certain personal circumstances preventing me from beginning hormone replacement therapy (HRT), I have been exploring alternatives with my medication for hair loss, hoping to enhance my breast growth, which is currently a C cup attributed to gynecomastia (yes, I acknowledge the size!). Recently, I obtained topical dutasteride and have been applying it to both my scalp and breast area. According to insights I gathered, since breast tissue has estrogen receptors and DHT can inhibit them, the application of dutasteride on my breasts might theoretically facilitate better estrogen absorption through these receptors. This is rooted in the idea that DHT's systemic effects could lead to a hormonal balance that favors estrogen over testosterone. Having maintained my C cup size for an extended period implies that my body may have an inclination towards estrogen, a notion that is supported by my past blood tests before I initiated treatment with finasteride, where I recorded a level of 44.5 pg/mL. While some may view this as a minor figure, it holds significance for someone who is pre-treatment. To highlight my current situation, I have been using this topical treatment for just two days. Upon waking today, I noticed discomfort around my nipple area (after sleeping on my chest), and even gentle pressure brought about a distinct pain. Although it’s not overly intense, the sensation is certainly apparent. I'm intrigued to know if this experience reflects a meaningful revelation about my body or if it’s purely coincidental. The visual changes appear to indicate improvement. While I am aware that it could be a placebo effect, there exists a possibility that it isn’t. I'm eager to hear thoughts and insights from others on this experience.

Thank you for sharing your detailed experience. It sounds like you are exploring options for breast development while managing the complexities of your situation. I will address your questions regarding dutasteride and its effects, particularly focusing on the discomfort you are experiencing.

Summary of Key Points:

  1. Dutasteride's Role: It's primarily used to reduce dihydrotestosterone (DHT) levels to treat hair loss and prostate enlargement. Its effect on breast tissue is less established and theoretical.
  2. Breast Discomfort: The pain you are feeling could be due to various factors, including hormonal changes, recent physical pressure, or even sensitivity from applying a new topical treatment.

Explanation:

Dutasteride acts to lower DHT, which can influence the hormonal balance in your body. Breast tissue has receptors for hormones, including estrogen, and theoretically, reducing DHT might allow for improved estrogen activity in breast tissue. However, this is not a widely studied or standardized use of the medication, and the evidence is largely anecdotal.

The discomfort around your nipple area after applying the topical dutasteride could be attributed to several reasons:

  • Physical Irritation: Sleeping on your chest might have contributed to soreness, especially if the area is sensitive.
  • Hormonal Fluctuations: Since dutasteride can alter hormone levels, it’s possible that your body is beginning to respond, but this would normally take more time than just two days.
  • Skin Reaction: Given that this is a new topical treatment, your skin may be reacting to the application.

Next Steps:

  1. Monitor Symptoms: Keep an eye on the discomfort. If pain worsens or you notice swelling or discharge, it may indicate an adverse reaction.
  2. Limit Pressure: Try to avoid sleeping on your chest for a while to reduce irritation. You might adopt positions that take pressure off your chest area.
  3. Adjust Usage: Since you’ve only been using dutasteride for two days, it may be beneficial to continue for a short period while monitoring any changes, but if discomfort persists, consider stopping use and waiting to see if symptoms resolve.
  4. Create a Diary: Record any changes in size, sensitivity, and overall comfort over the weeks. This can help you remember any shifts and patterns related to your treatment.
  5. Research and Educate: Since your approach to enhacing breast growth isn’t traditional, it can be worthwhile to gather more information and potentially seek communities with similar experiences who might offer additional insights.

I appreciate your quest for understanding your body's reactions and choices. Remember to prioritize your comfort and health as you explore options. If discomfort continues or worsens, please consider discussing these findings and your experience with a trusted healthcare professional.

Could It Be a Burst Ovarian Cyst?

I'm a 32-year-old woman weighing 110 pounds and standing at 5 feet tall. I do not smoke, drink alcohol, nor use recreational drugs. Yesterday, between midnight and 4 a.m., I was hit with sudden, intense pain in my lower abdomen. The discomfort was so severe that it felt like I was being stabbed with knives whenever I moved. It was an agonizing experience, unlike anything I had previously encountered. I also felt lightheaded, experienced chills, and endured some painful vomiting. I was essentially immobilized, but thankfully, the pain began to ease a bit, allowing me to eventually visit urgent care. At the clinic, the doctor examined me and sent me home, suggesting that various conditions could be the cause of my distress, advising me to seek emergency care if a fever developed. Later that same night, I noticed brown, bloody discharge, which raised my concern about a possible ovarian cyst, especially since they run in my family. Currently, I am still suffering from pain that prevents me from standing up straight or walking normally. How long can I expect this to persist? Over-the-counter pain relief isn't working for me, which is incredibly frustrating. I'm seeking some guidance since I have had similar pain before, but nothing that lasted this long. Typically, doctors tend to brush it off. Could anyone offer some advice?

Exploring Bilateral Ovarian Fibromatosis: Seeking Guidance for a Rare Condition

I’m a 28-year-old female, standing at 5’4” (162 cm) and weighing 222 lbs (101 kg). Currently, I'm on escitalopram and Ritalin for managing depression and ADHD. **Background Story:** My menstrual journey began early, at age eight, and has been characterized as typically heavy. In November 2024, I experienced my first missed period with no chance of pregnancy since I wasn't in a relationship—initially, I felt relieved to have a break from menstruation. By December 2024, I traveled to Germany to visit an ex. Interestingly, after we were intimate, my period resumed. However, the bleeding continued excessively for several weeks, escalating to 5, 10, and then even 15 days. When I sought help at an emergency clinic in Germany, the doctor informed me that I had "a lot more to shed". I was advised to return to Ireland for further assessment if the bleeding persisted after ten days. They identified a small cyst, about 2 cm, on my right ovary, deemed too minor for any immediate intervention. Returning to Ireland in late January 2025, I went to the Accident and Emergency (A&E) department due to ongoing bleeding. They prescribed tranexamic and mefenamic acid and sent me home. Throughout 2025, my menstrual cycles became increasingly erratic, with intervals stretching between 50 to 70 days, followed by prolonged bleeding lasting around 20 days. A particularly concerning episode occurred from October to December 2025 when I bled continuously for 50 days. Between September and November 2025, I had three separate visits to emergency departments. One of these trips was to a maternity hospital, hoping for better care. Another incident involved an ambulance due to sudden, severe pain that required stretcher transport. Although I was later told it was back pain, I disagreed; I am familiar with sciatica and this felt distinctly different. I suspect it may have been ovarian torsion, briefly twisting before returning to its original state. Each visit concluded with prescriptions for more tranexamic acid and pain relief medication. In October 2025, I underwent transvaginal and abdominal ultrasounds, which detected a significant cyst (possibly the same one) on my right ovary and a small mural nodule. This led to an MRI exam. The pelvic MRI performed in November 2025 confirmed the cyst was simple yet measured approximately 7 cm x 6 cm x 6 cm. Alarmingly, the report also noted that both ovaries exhibited an “unusual appearance.” It mentioned a “T2 signal rim” and described it as a “Black Garland sign,” indicative of bilateral ovarian fibromatosis. I had an appointment with a gynecologist just two days ago, and while they recommended further scans, I was troubled to learn that they had no prior knowledge of ovarian fibromatosis. In my quest for answers post-MRI report, I conducted my own research (not out of distrust, but rather from a sense of deficiency in the information provided), and I discovered that ovarian fibromatosis, albeit benign, is extremely uncommon. Reports suggest there have been roughly 30 cases documented in the last three decades, with most being unilateral. My case is bilateral, making it even rarer. Now, I am left pondering whether I should seek treatment abroad for this condition. Are there any specialists in my area familiar with ovarian fibromatosis? The specialist indicated that the gynecological team at my hospital would convene to discuss my case to see if any team member has relevant experience, which adds to my apprehension. I appreciate any insights or advice that could help guide my next steps!

Concerns About Birth Control and Spotting

At the age of 40 and weighing 120 pounds, I've been using the same form of birth control for seven years. Recently, I've noticed unusual spotting that begins about ten days prior to my period, occurring consistently during each cycle. While I still experience a slight menstrual flow when my period is due, the spotting has become a recurring issue. I underwent a routine pap smear and had both a pelvic ultrasound and a transvaginal ultrasound, which revealed a thin endometrial lining measuring 3.2 mm. Consequently, my gynecologist changed my birth control to a different type of progestin and instructed me to return in two months. In the first month after the switch, I didn’t experience any spotting - a welcome change. However, I did notice some spotting occurring after intercourse, which is something I haven’t encountered before. Currently, I’m midway through my second pack of birth control and have had slight spotting again, particularly with sexual activity. My doctor mentioned that if the spotting persists, she would recommend a biopsy of the lining, even though she assessed that it was unlikely to indicate a serious issue. I’m left wondering if my body is still adapting to the new hormones or if this situation warrants an earlier visit to the doctor instead of waiting for my scheduled follow-up at the end of February. Any thoughts or insights on this matter would be greatly valued.

Unusual Changes in My Menstrual Cycle

Hello everyone! I've noticed that my menstrual cycle has become quite irregular lately; this marks the second time my period has been delayed by over a week, which is unusual for me. Considering the stress I've been under recently, I suspect it might be a contributing factor. However, I'm worried this could be an early sign of pre-menopause. Additionally, I'm uncertain about how to track my cycle going forward. Should I start counting from the date of this last period, or revert to my previous schedule? Thanks for your insights!
