What it is
From: Orphanet
Functioning gonadotropic adenoma is a very rare pituitary tumor, macroscopically characterized by a soft, well vascularized, variable sized adenoma, with occasional areas of hemorrage or necrosis, that secretes biologically active gonadotropins. In addition to common neurological signs due to mass effect (headache and/or visual field deterioration), additional clinical manifestations include menstrual irregularities (secondary amenorrhea, oligomenorhea or severe menorrhagia), galactorrhea, infertility or ovarian hyperstimulation syndrome (in premenopausal women), testicular enlargement and, occasionally, hypogonadism (in men) and isosexual precocious puberty (in children).
Reported clinical features and what the terms mean
The following findings are associated with this condition in Orphanet. They are not a checklist for diagnosing yourself, and they do not all occur in every affected person. Some are examination, imaging or laboratory findings that cannot be recognised at home.
The frequency labels describe how often a finding was reported among people with the condition in the source. They do not give the chance that a person with that symptom has the condition. Definitions below reproduce HPO terminology; they explain the term, not the likely severity in an individual.
- Pituitary gonadotropic cell adenoma · Obligate (100%)
- A type of pituitary adenoma that produces gonadotropins.
- Abnormality of the menstrual cycle · Frequent (79-30%)
- An abnormality of the ovulation cycle.
- Anterior hypopituitarism · Frequent (79-30%)
- A condition of reduced function of the anterior pituitary gland characterized by decreased secretion of one or more of the pituitary hormones growth hormone, thyroid-stimulating hormone, adrenocorticotropic hormone, prolactin, luteinizing hormone, and follicle-stimulating hormone.
- Decreased female libido · Frequent (79-30%)
- Diminished sexual desire in female.
- Fatigue · Frequent (79-30%)
- A subjective feeling of tiredness characterized by a lack of energy and motivation.
- Impotence · Frequent (79-30%)
- Inability to develop or maintain an erection of the penis.
- Increased serum testosterone level · Frequent (79-30%)
- An elevated circulating testosterone level in the blood.
- Visual impairment · Frequent (79-30%)
- Visual impairment (or vision impairment) is vision loss (of a person) to such a degree as to qualify as an additional support need through a significant limitation of visual capability resulting from either disease, trauma, or congenital or degenerative conditions that cannot be corrected by conventional means, such as refractive correction, medication, or surgery.
- Abnormal prolactin level · Frequent (79-30%)
- Infertility · Frequent (79-30%)
- Visual field defect · Frequent (79-30%)
- Abnormality of secondary sexual hair · Occasional (29-5%)
- Abnormality of the growth of secondary sexual hair, which normally ensues during puberty. In males, secondary sexual hair usually comprises body hair, including underarm, abdominal, chest, and pubic hair. In females, secondary sexual hair usually comprises a lesser degree of body hair, most prominently underarm and pubic hair.
- Adrenocorticotropic hormone deficiency · Occasional (29-5%)
- A reduced ability to secrete adrenocorticotropic hormone (ACTH), a hormone that stimulates the adrenal cortex to secrete of glucocorticoids such as cortisol.
- Amenorrhea · Occasional (29-5%)
- Absence of menses for an interval of time equivalent to a total of more than (or equal to) 3 previous cycles or 6 months.

Which doctor should you see?
The suggested department for discussing Functioning gonadotropic adenoma is Endocrinology, with a endocrinologist as the relevant type of clinician. General physician / Family Medicine; paediatrician for children. Referral depends on symptoms.
This is an editorial referral starting point. The appropriate clinic depends on the person’s age, symptoms, previous diagnosis and local services. The first clinician can decide whether another specialty or a team is needed; a department label does not confirm the diagnosis.
How to prepare for an assessment
Bring a short timeline of the main symptoms: when they first appeared, whether they are constant or episodic, what seems to change them, and how they affect daily activities. Include previous reports, discharge summaries, current medicines and supplements, allergies, and any relevant family history. A dated record is more useful than trying to match every feature in an online article.
Ask the clinician what is already established and what remains uncertain. If a test is suggested, ask what question it answers, what its limitations are and how the result would change the next step. The information here is not an instruction to arrange every possible test. In children, bring growth, developmental and school information if it is relevant to the concern.
- Which hormone or metabolic finding is important in this case?
- How should test timing and current medicines be taken into account?
- What follow-up would show whether the care plan is working?
Treatment discussions and follow-up
The material gathered for this draft does not provide a complete condition-specific treatment pathway for Functioning gonadotropic adenoma. That gap does not mean that treatment is unavailable. A clinician needs to establish the diagnosis and review current guidance before recommending medicines, procedures, rehabilitation or other support.
Before leaving the appointment, clarify the next review date, who will communicate results, and whom to contact if the situation changes. Discuss difficulties with sleep, work, school, mobility, eating or emotional wellbeing when these are relevant. Practical support may require coordination between the treating clinician and other services.
The collected references do not establish a complete prevention or long-term outlook section for this entry. Missing information should not be interpreted as proof that prevention is impossible or that a particular outcome is inevitable. Ask what is known for the exact subtype, stage and personal circumstances, and which uncertainties remain.
When to seek emergency help
Severe breathing difficulty, collapse, new stroke-like symptoms, a seizure that is prolonged or repeated without recovery, uncontrolled major bleeding, or an immediate risk of self-harm require emergency help. In India, call 112 or reach the nearest emergency department. This is a general, non-exhaustive warning list; it is not a condition-specific triage tool.
This condition is usually assessed by an endocrinologist. Every profile shows the doctor’s registration and what has been checked.
