Ntali G, Capatina C. Updating the Landscape for Functioning Gonadotroph Tumors. Medicina (B Aires) 2022; 58:medicina58081071.

Abstract
Functioning gonadotroph adenomas (FGAs) are rare tumors, as the overwhelming majority of gonadotroph tumors are clinically silent. Literature is based on case reports and small case series. Gonadotroph tumors are poorly differentiated and produce and secrete hormones inefficiently, but in exceptional cases, they cause clinical syndromes due to hypersecretion of intact gonadotropins. The clinical spectrum of endocrine dysfunction includes an exaggerated response of ovaries characterized as ovarian hyperstimulation syndrome (OHSS) in premenopausal females and adolescent girls, testicular enlargement in males, and isosexual precocious puberty in children. Transsphenoidal surgery and removal of tumor reduces hormonal hypersecretion, improves endocrine dysfunction, and provides tissue for further analysis. Medical therapies (somatostatin analogues, dopamine agonists, GnRH agonists/antagonists) are partially or totally ineffective in many cases, especially with respect to antitumor effect. This review aims to update recent literature on these rare functioning tumors and highlight their therapeutic management.

Abstract
PURPOSE To summary the clinical features of premenopausal women with functioning gonadotroph adenomas (FGAs) and preliminarily explore their molecular characterization. METHODS 12 premenopausal females with FGAs in our center were retrospectively analyzed. Previously reported cases were also summarized. The patients were clinically divided into FSH- or LH-predominant types according to their preoperative serum FSH/LH ratio. The expressions of related genes in the tumor tissues of female FGAs, non-functioning gonadotroph adenomas (NFGAs), and silent corticotropin adenomas were evaluated by RT-qPCR. RESULTS Of all the 12 patients with FGAs from our center, 11 (91.7%) were diagnosed as FSH-predominant type, and they all had menstrual disorders, including 9 with spontaneous ovarian hyperstimulation syndrome (sOHSS). Their hormonal profiles showed non-suppressed FSH (12.45 ± 7.34 IU/L) with hyperestrogenemia [median estradiol level 1353.0 pg/mL (636.0, 3535.0)]. The other patient (8.3%) with LH-predominant type mainly manifested with infertility and sustained elevated serum LH without FSH or estradiol increasing. 65 premenopausal FGAs patients were systematic reviewed. 60 patients (92.3%) were FSH-predominant type, including 86.7% presented with menstrual disorders, 16.7% reported infertility, and 98.2% (55/56) showed sOHSS. No sOHSS or hyperestrogenemia were found in the 5 patients (7.7%) with LH-predominant type. Pituitary imaging data revealed macroadenomas and microadenomas accounted for 89.2% and 10.8%, respectively. Of 63 patients (96.9%) who underwent pituitary adenoma resection, 77.8% had complete tumor resection and no recurrence at the last follow-up. The relative expressions of KISS1 mRNA were significantly higher in FGA group than in NFGA group (p = 0.018), and significantly positively correlated with the preoperative serum estradiol levels (p = 0.004). CONCLUSIONS Different clinical features were observed in premenopausal women with FGAs of FSH- or LH-predominant types. The elevated KISS1 expression in tumor tissues might involve in the secretion function of FGAs.

Abstract
To assess whether the follicle-stimulating hormone (FSH) subunits observed in patients with gonadotroph adenomas (GA) can cause infertility, the effects of subunits and heterodimeric FSH on the in vitro follicle development were evaluated in mice. The partial forms of FSH in follicle culture did not induce development into pseudoantral follicles, whereas follicles cultured with native FSH developed into pseudoantral follicles and produced mature metaphase II oocyte. Therefore, intact FSH is needed for folliculogenesis, implying that production of FSH with a partial structure in GA may result in infertility.

Gonadotroph Pituitary Adenoma Causing Treatable Infertility and Ovarian Hyperstimulation Syndrome in Female Patients: Neurosurgical, Endocrinologic, Gynecologic, and Reproductive Outcomes. World Neurosurg 2021; 150:e162-e175. [PMID: 33684575 DOI: 10.1016/j.wneu.2021.02.115] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2021] [Revised: 02/22/2021] [Accepted: 02/26/2021] [Indexed: 12/18/2022]
Abstract
BACKGROUND Gonadotroph pituitary adenoma (Gn-PA) may rarely cause ovarian hyperstimulation syndrome, leading to infertility in women, although this remains poorly described. METHODS We present a quantitative systematic review including 2 patients from our institutional and 48 from the literature with Gn-PA causing ovarian hyperstimulation syndrome to thoroughly describe the clinical features and therapeutic outcomes from multidisciplinary aspects. RESULTS The patients had a mean age of 31.5 years and a mean follicle-stimulating hormone level of 14.4 IU/L. Estradiol level was high in 82% of patients, at >350 pg/mL. The mean maximal adenoma diameter was 22 mm, with a Knosp grade ≥3 in 10 patients. Abdominal surgery preceded adenoma resection in 24 patients (48%). Among 25 patients for whom extent of resection was recorded, total adenoma resection was achieved in 12. Through a mean follow-up of 25 months, adenoma recurrence was observed in 5 patients, who were treated with re-resection (n = 2), radiation (n = 2), and medical therapy followed by bilateral oophorectomy (n = 1). Medical therapies were partially effective or ineffective, and adenoma shrinkage did not follow; gonadotropin-releasing hormone agonists/antagonists were partially effective in 20% of patients (2/10), dopamine agonists in 44% (8/18), and somatostatin analogues in 50% (1/2). Four experienced swelling of tumor/ovaries after gonadotropin-releasing hormone agonists/antagonists administration. Overall, chemical remission was obtained in 26 of 28 patients, normalization of ovaries in 25 of 27, and successful pregnancy in 12 of 14. CONCLUSIONS Adenoma resection is the main treatment, leading to reduction in ovarian size and biochemical remission, with a high likelihood of subsequent spontaneous pregnancy. Increased awareness of this rare condition may help avoid unnecessary abdominal procedures.

Abstract
Adequate maternal thyroid hormone (TH) is necessary for fetal brain development. The role of placental human chorionic gonadotropin (hCG) in ensuring the production of TH is less well understood. The objective of the study was to evaluate 1) associations of placental hCG and its subunits, and maternal TH in the second trimester, and 2) the single and joint effects of TH and placental hormones on cognitive development and communication at ages 1 and 3 years. Fifty individuals (5%) were selected from the CANDLE (Conditions Affecting Neurocognitive Development and Early Learning) pregnancy cohort in Memphis, Tennessee, with recruitment from 2006 to 2011, to equally represent male and female fetuses. Participants were 68% Black and 32% White. Hormones measured were maternal thyroid (thyrotropin [TSH] and free thyroxine [FT4]) and placental hormones (hCG, its hyperglycosylated form [hCG-h], and free - [hCG] and -subunits [hCG]) in maternal serum (17-28 weeks). The primary outcome measurement was the Bayley Scales of Infant and Toddler Development. All forms of hCG were negatively associated with FT4 and not associated with TSH. hCG was associated with cognitive development at age 1 year and jointly interacted with TSH to predict cognitive development at age 3 years. This pilot study added insight into the thyrotropic actions of hCG in the second trimester, and into the significance of this mechanism for brain development. More research is warranted to elucidate differences between hCG, hCG, and hCG-h in relation to TH regulation and child brain function.

A Case of Recurrent Hemorrhagic Corpus Luteum with Elevated Follicle-Stimulating Hormone, Controlled by Estrogen/Gestagen Therapy. Case Rep Obstet Gynecol 2020; 2020:4098085.

Abstract
A high secretion of follicle-stimulating hormone (FSH) in reproductive-aged women is unusual. We report a case of recurrent corpus luteum hemorrhage and subsequent ovarian torsion with markedly elevated FSH levels in a reproductive-aged woman in the absence of functional gonadotroph adenoma (FGA) or premature ovarian failure (POF). A 22-year-old nulligravid woman with a history of bilateral hemorrhagic corpus luteum and subsequent ovarian torsion presented with acute abdominal pain. An emergency salpingo-oophorectomy of the right side was performed, and the right ovarian torsion due to hemorrhagic corpus luteum was diagnosed. Laboratory tests revealed markedly elevated FSH levels (77.6 mIU/mL). FGA was suspected, but no evidence of tumor was identified. The left ovary enlarged again at one-month follow-up. Estrogen/gestagen therapy (EGT) was started, which reduced the enlarged ovary to normal size. Two years later, her pituitary hormonal status was evaluated in detail. Besides markedly elevated FSH level, slightly elevated LH (31.2 mIU/mL), normal total inhibin B (35.3 pg/ml), abnormally low anti-Müllerian hormone (AMH) (<0.03 ng/mL), and poor FSH response to gonadotropin-releasing hormone stimulation test were found. In the absence of FGA, we conclude that certain disorders of inhibitory factors for FSH function, including inhibin and AMH may exist, which could attribute to the patient's symptoms. EGT was very effective in suppressing the ovarian hyperactivity.

Abstract
CONTEXT Despite the new opportunities provided by assisted reproductive technology (ART), male infertility treatment is far from being optimized. One possibility, based on pathophysiological evidence, is to stimulate spermatogenesis with gonadotropins. EVIDENCE ACQUISITION We conducted a comprehensive systematic PubMed literature review, up to January 2020, of studies evaluating the genetic basis of follicle-stimulating hormone (FSH) action, the role of FSH in spermatogenesis, and the effects of its administration in male infertility. Manuscripts evaluating the role of genetic polymorphisms and FSH administration in women undergoing ART were considered whenever relevant. EVIDENCE SYNTHESIS FSH treatment has been successfully used in hypogonadotropic hypogonadism, but with questionable results in idiopathic male infertility. A limitation of this approach is that treatment plans for male infertility have been borrowed from hypogonadism, without daring to overstimulate, as is done in women undergoing ART. FSH effectiveness depends not only on its serum levels, but also on individual genetic variants able to determine hormonal levels, activity, and receptor response. Single-nucleotide polymorphisms in the follicle-stimulating hormone subunit beta (FSHB) and follicle-stimulating hormone receptor (FSHR) genes have been described, with some of them affecting testicular volume and sperm output. The FSHR p.N680S and the FSHB -211G>T variants could be genetic markers to predict FSH response. CONCLUSIONS FSH may be helpful to increase sperm production in infertile men, even if the evidence to recommend the use of FSH in this setting is weak. Placebo-controlled clinical trials, considering the FSHB-FSHR haplotype, are needed to define the most effective dosage, the best treatment length, and the criteria to select candidate responder patients.

Abstract
PURPOSE Gonadotroph adenomas are pituitary adenomas with inefficient and variable secretory characteristics, that is why they are usually considered as a subgroup of nonfunctioning pituitary adenomas (NFPA) and are recognized only at immunohistochemistry. When gonadotroph adenomas secrete active hormones, they may cause spontaneous ovarian hyperstimulation syndrome (OHSS) in premenopausal women. Aim of our study is to describe three women with OHSS diagnosed before the removal of the adenoma and to calculate the prevalence of OHSS in premenopausal women with a clinical diagnosis of NFPA. METHODS We reviewed clinical records of premenopausal women that underwent neurosurgery for NFPA at our centre between 1993 and 2014. OHSS was diagnosed in patients with high levels of FSH, suppressed LH, hyperestrogenism, abdominal symptoms, polymenorrhea, enlarged ovaries with cysts or previous surgery for ovarian cysts. RESULTS 171 women were included into the study; 62 (36.6%) had a gonadotroph adenoma diagnosed at immunohistochemistry. Two patients were retrospectively diagnosed as having OHSS due to gonadotroph adenoma and three had OHSS diagnosed before neurosurgery. The prevalence of OHSS was 2.9% in the overall group of patients with NFPA and 8.1% among patients with a gonadotroph adenoma detected at immunohistochemistry. CONCLUSIONS Frequency of OHSS due to a gonadotroph adenoma is not negligible. Increased awareness of the characteristic clinical and hormonal picture should permit an early detection of this condition in premenopausal women with a pituitary adenoma.

Abstract
Clinically nonfunctioning pituitary adenomas (NFPA) are the most common pituitary tumors after prolactinomas. The absence of clinical symptoms of hormonal hypersecretion can contribute to the late diagnosis of the disease. Thus, the majority of patients seek medical attention for signs and symptoms resulting from mass effect, such as neuro-ophthalmologic symptoms and hypopituitarism. Other presentations include pituitary apoplexy or an incidental finding on imaging studies. Mass effect and hypopituitarism impose high morbidity and mortality. However, early diagnosis and effective treatment minimizes morbidity and mortality. In this publication, the goal of the Neuroendocrinology Department of the Brazilian Society of Endocrinology and Metabolism is to provide a review of the diagnosis and treatment of patients with NFPA, emphasizing that the treatment should be performed in reference centers. This review is based on data published in the literature and the authors' experience. Arch Endocrinol Metab. 2016;60(4):374-90.

Abstract
BACKGROUND Most pituitary adenomas with FSH- or LH-positive immunohistochemistry are endocrinologically silent, and neurological symptoms due to their large volume are the first clinical signs; they are rarely reported to be secreting gonadotropins, this usually occurring in cases with clinical endocrine findings. Gonadotropinomas are often treated surgically because they are unresponsive to conventional medical therapies. Temozolomide was recently recommended for non-responder aggressive pituitary adenoma management. CASE REPORT A 43-year-old male with a history of 5 years of erythrocytosis presented with severe headache, orthostatic dizziness, and difficulty walking. MRI documented a giant pituitary adenoma and high uptake of 111In-pentetreotide indicated somatostatin receptor (SSR) expression. Biochemical tests revealed a secreting gonadotropinoma. Therapy with somatostatin analogs and dopamine agonists improved the patient's headache, achieved partial hormone control, slightly reduced the size of the adenoma, and controlled erythrocytosis. Six months after the diagnosis, hormone escape occurred despite therapy, thus neurosurgery was performed. After the procedure the patient died of untreatable intracranial hypertension. The surgical specimen revealed SSR 2 and 3 expression, and temozolomide did not induce apoptosis in primary cell culture. REVIEW OF LITERATURE Among gonadotropinomas, female gender (77%), macroadenoma (84%), young age at diagnosis (28 ± 12 years), delay from first symptoms to diagnosis (up to 15 years), and ovarian cysts/menstrual disorders in females or macro-orchidism in males were the foremost clinical and neuroimaging features. CONCLUSIONS Male gonadotropin-secreting pituitary adenomas may have a variable clinical expression secondary to testosterone excess. Somatostatin analogs, dopamine agonists or temozolomide may have a role that needs to be assessed case by case.

Follicle-stimulating hormone-secreting pituitary adenoma manifesting as recurrent ovarian cysts in a young woman--latent risk of unidentified ovarian hyperstimulation: a case report. BMC Res Notes 2013; 6:408. [PMID: 24119690 PMCID: PMC3852055 DOI: 10.1186/1756-0500-6-408] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2013] [Accepted: 10/07/2013] [Indexed: 12/20/2022] Open
Abstract
Background Ovarian hyperstimulation caused by follicle-stimulating hormone-secreting gonadotroph cell adenoma is a rare, with a few reported cases, but almost certainly unnoticed cases occur because of the absence of detailed examinations. We retrospectively reviewed 200 patients treated for gonadotroph cell adenoma in our institute and identified 26 women of reproductive age. Two of these 26 patients had a history of ovarian cysts. One patient was considered to have had typical ovarian hyperstimulation, successfully treated by transsphenoidal surgery. The other patient initially underwent transsphenoidal surgery because of visual disturbance, but endocrinological examinations suggested possible relationships with previous ovarian hyperstimulation. We present the former case and discuss the latent risk of failure to identify this entity. Case presentation A 36-year-old woman with a sellar tumor was referred to our hospital with suspected ovarian hyperstimulation. She had a history of repeated surgery for ovarian cysts. Serum follicle-stimulating hormone and estradiol levels were within the normal ranges, and only the luteinizing hormone level was suppressed significantly. Transsphenoidal surgery achieved gross total tumor removal, and the histological diagnosis was follicle-stimulating hormone-secreting gonadotroph cell adenoma. The serum follicle-stimulating hormone, luteinizing hormone, and estradiol levels returned to the normal ranges postoperatively, and the ovarian cysts subsequently decreased in size without particular interventions. Conclusion Ovarian hyperstimulation could regress after resolving the causes of high follicle-stimulating hormone level, so avoiding unnecessary ovary surgery. Detailed endocrinological examination including estradiol evaluation with pituitary imaging is quite important in women of reproductive age to establish the correct diagnosis.

Abstract
Spontaneous ovarian hyperstimulation syndrome (sOHSS) is a rare event that may result from a FSH-producing pituitary adenoma (FSHoma), activating mutations of the FSH receptor (FSHR), and cross-reactivity of the FSHR to elevated hCG and TSH in the setting of pregnancy or hypothyroidism. The objective of this study was to investigate whether an aberrant FSHR was present in a woman with sOHSS and a non-surgically diagnosed FSHoma whose serum FSH levels and FSH bioactivity were nearly normal. Sequencing of the patient's FSHR gene revealed a heterozygous novel missense mutation c. 1536G>A resulting in an amino acid substitution M512I. We asked whether this mutant FSHR affected FSHR-mediated signaling pathways involving cAMP/protein kinase A (PKA), phosphatidylinositol-3 kinase (PI3K)/protein kinase B (AKT) and v-src sarcoma (Schmidt-Ruppin A-2) viral oncogene homolog kinase (SRC)/ p42/p44 extracellular signal-regulated protein kinases (ERK1/2). Thus, 293T cells expressing wild-type (FSHRwt), the mutant FSHR (FSHRmt), or both (FSHRwt/mt) were treated with FSH and subjected to measurements of intracellular cAMP, cAMP-induced CRE (cAMP response element)-mediated luciferase assays and immunoblot analyses of phosphorylated PI3K and ERK1/2. There were no differences in luciferase activities or phosphorylation levels of ERK1/2 among FSHRwt, FSHRmt cells and FSHwt/mt cells. However, FSHRmt cells showed a significant reduction in both cAMP production and PI3K phosphorylation levels with unchanged phosphorylation of ERK1/2 upon FSH stimulation in comparison to FSHwt cells. Also, FSH treatment did not provoke PI3K phosphorylation in FSHwt/mt cells. These results indicate that the novel missense M512I FSHR mutation identified herein did not participate in hyperactivation of FSHR-mediated signaling pathways but rather in hypoactivation of the FSH-mediated PI3K/AKT pathway. Thus, this study demonstrates a new functional property of this novel mutatnt FSHR, which, however, might not be involved in the pathogenesis of sOHSS in this FSHoma patient.

Abstract
The follicle stimulating hormone (FSH), luteinizing hormone (LH) and chorionic gonadotropin (HCG) play a critical role in human reproduction. Despite the common evolutionary ancestry and functional relatedness of the gonadotropin hormone beta (GtHB) genes, the single-copy FSHB (at 11p13) and the multi-copy LHB/CGB genes (at 19q13.32) exhibit locus-specific differences regarding their genomic context, evolution, genetic variation and expressional profile. FSHB represents a conservative vertebrate gene with a unique function and it is located in a structurally stable gene-poor region. In contrast, the primate-specific LHB/CGB gene cluster is located in a gene-rich genomic context and demonstrates an example of evolutionary young and unstable genomic region. The gene cluster is shaped by a constant balance between selection that acts on specific functions of the loci and frequent gene conversion events among duplicons. As the transcription of the GtHB genes is rate-limiting in the assembly of respective hormones, the genomic and genetic context of the FSHB and the LHB/CGB genes largely affects the profile of the hormone production.

Abstract
BACKGROUND We report a highly exceptional case in which a gonadotroph adenoma was diagnosed in a patient with normal follicle-stimulating hormone (FSH) levels. CASE A 30-year-old woman with a gonadotroph adenoma presented with hyperstimulation syndrome and normal FSH levels. After treatment of her adenoma she had regular menstrual cycles and subsequently conceived. CONCLUSION Ovarian hyperstimulation caused by a gonadotroph adenoma in a premenopausal woman with normal FSH levels is extremely rare. However, we propose that gonadotroph adenomas be considered in the differential diagnosis of patients who have this constellation of abnormalities.

Abstract
OBJECTIVE To report the effect of cabergoline on ovarian hyperstimulation syndrome associated with gonadotropin-secreting pituitary adenomas. DESIGN Case report. SETTING Outpatient practice. PATIENT(S) Two women with menstrual irregularity, enlarged ovaries, high E(2), and normal gonadotropin levels. INTERVENTION(S) Cabergoline treatment and transsphenoidal surgery. MAIN OUTCOME MEASURE(S) Estradiol levels, transvaginal ultrasonography, and pituitary magnetic resonance imaging. Transsphenoidal surgery showed pituitary adenoma staining for LH in both patients. RESULT(S) Cabergoline was effective in reducing E(2) levels and decreasing ovarian size but ineffective in shrinking the pituitary adenomas. CONCLUSION(S) This is the first description of the effectiveness of cabergoline as the primary treatment of spontaneous ovarian hyperstimulation syndrome in patients with gonadotropin-producing pituitary adenomas.

Abstract
OBJECTIVE To report a case of a follicle-stimulating hormone (FSH)-secreting pituitary adenoma, which manifested with oligomenorrhea, dysmenorrhea, and multiple bilateral ovarian cysts. METHODS We present a case report of a 29-year-old woman, including detailed laboratory, radiologic, and pathologic findings, who was diagnosed as having an FSH-secreting pituitary tumor. The pertinent literature is also reviewed. RESULTS A 29-year-old woman, after experiencing oligomenorrhea and increasing abdominal girth for >1 year, presented with an acute abdomen. Ultrasonography revealed multicystic ovaries >15 cm in maximal diameter, causing bilateral adnexal torsion. After bilateral ovarian cystectomies, ultrasound study showed recurrence of the cysts. Relevant laboratory data were as follows: serum FSH 6.8 mIU/mL, luteinizing hormone 0.1 mIU/mL, prolactin 67 ng/mL, human chorionic gonadotropin <2 mIU/mL, progesterone 3.5 ng/dL, estradiol 237 pg/mL, thyrotropin 1.8 microIU/mL, testosterone <4 ng/dL, insulin 8.0 microIU/mL, and fasting plasma glucose 87 mg/dL. Magnetic resonance imaging (MRI) of the brain revealed a 2.5-cm pituitary mass, although the patient had no symptoms of pituitary dysfunction. Transsphenoidal removal of the mass was performed, and pathology studies were positive for FSH-secreting adenoma. Repeated MRI at 3 months showed an 0.8-cm residual tumor. The patient refused adjuvant radiotherapy. Regular menses resumed within 2 months postoperatively, and she later successfully became pregnant. Almost 3 years after treatment, the patient remained asymptomatic, results of pituitary function tests were normal, and follow-up MRI showed no signs of tumor regrowth. CONCLUSION Although very uncommon, gonadotropin-secreting pituitary adenomas should be considered in the differential diagnosis of new-onset oligomenorrhea and dysmenorrhea, especially if associated with multicystic ovaries on ultrasound study, even in the absence of elevated levels of serum gonadotropins. Furthermore, we propose that it may be acceptable to withhold adjuvant radiotherapy in patients who are asymptomatic after transsphenoidal surgical excision of these tumors.

Abstract
OBJECTIVE We present a case of spontaneous ovarian hyperstimulation caused by pituitary gonadotroph macroadenoma, and include a review of the literature. CASE REPORT A 27-year-old woman presented with irregular menstruation and bilateral multicystic enlargement of the ovaries. Serum estradiol (E(2)) levels were marginally elevated for the follicular phase but within the physiological range. Serum luteinizing hormone (LH) was extremely low, follicle-stimulating hormone (FSH) was normal, and prolactin (PRL) was high. Magnetic resonance imaging disclosed a pituitary macroadenoma. Immunohistochemical examination of the surgically removed adenoma showed intense reactivity for FSH and LH. After the operation, E(2), LH and PRL levels were normalized, the ovaries returned to a normal morphology, and regular menstrual cycles were resumed. CONCLUSION A review of the literature showed that ovarian hyperstimulation caused by pituitary gonadotroph adenoma is not always accompanied by elevated FSH levels. High PRL and E(2) and low LH were reported in the majority of the cases, but E(2) may stay within the range observed in normal menstrual cycles.

Abstract
OBJECTIVE To describe the clinical symptoms associated with the diagnosis of pituitary gonadotroph adenoma in premenopausal women. DESIGN Report of three separate cases. SETTING University medical center. PATIENT(S) Three patients: a 31-year-old woman with primary infertility, recurrent adnexal masses, and highly elevated estradiol level; a 30-year-old woman with recurrent multicystic ovaries following multiple cystectomies and transvaginal cyst aspirations, and elevated estradiol level; a 43-year-old woman with bilateral complex cystic adnexal masses and an elevated estradiol level, who underwent a total abdominal hysterectomy and bilateral salpingo-oophorectomy for a suspected granulosa cell tumor. INTERVENTION(S) Transsphenoidal resection of a pituitary mass. MAIN OUTCOME MEASURE(S) Serum estradiol, FSH, and LH levels; transvaginal ultrasonography of the ovaries; histologic examination of pituitary tumors. RESULT(S) Transsphenoidal resection of pituitary adenomas resulted in normalization of serum estradiol and FSH levels and resolution of adnexal masses in two of the women. CONCLUSION(S) Pituitary gonadotroph adenoma must be considered in the differential diagnosis in reproductive-aged women presenting with the clinical symptom triad of new onset oligomenorrhea, bilateral cystic adnexal masses, and elevated estradiol and FSH levels with suppressed levels of LH; timely diagnosis may prevent unnecessary and potentially damaging surgical procedures.

Abstract
OBJECTIVE To report a case of a gonadotroph adenoma diagnosed after a dramatic increase in estradiol level and ovarian hyperstimulation in response to a gonadotropin-releasing hormone agonist. DESIGN Case report. SETTING Outpatient practice and university hospital. PATIENT(S) A 35-year-old woman who presented with infertility, amenorrhea, and an elevated basal estradiol concentration. INTERVENTION(S) Ultrasonography, laparoscopy, endocrinologic assays, magnetic resonance imaging, transsphenoidal surgery, and immunocytochemical staining. MAIN OUTCOME MEASURE(S) Ultrasonography and laparoscopy demonstrated bilaterally enlarged ovaries containing multiple preovulatory follicles, similar in appearance in those women undergoing controlled ovarian hyperstimulation with exogenous FSH. The serum estradiol level was moderately elevated, the FSH level was within the normal range, and LH was suppressed. Administration of leuprolide acetate resulted in very elevated estradiol concentrations and even larger ovarian cysts. Magnetic resonance imaging demonstrated a sellar mass. Examination of the tissue excised by transsphenoidal excision of the mass showed a pituitary adenoma that stained strongly for FSH. RESULT(S) Regular menses resumed soon after excision of the gonadotroph adenoma, followed by a spontaneous pregnancy. CONCLUSIONS Gonadotroph adenoma should be suspected in a reproductive age woman with oligomenorrhea or amenorrhea, infertility, multiple preovulatory follicles, and a persistently elevated serum estradiol concentration. Exacerbation of the ovarian hyperstimulation in response to a gonadotropin-releasing hormone agonist in this setting also strongly suggests a gonadotroph adenoma but can be avoided by recognizing the presenting features of this condition.

Abstract
Endocrine inactive pituitary adenomas represent about one quarter of all pituitary tumors. By immunocytochemistry, most of these tumors are positive for intact gonadotropins and/or their subunits. Clinical presentation is usually secondary to mass effect symptoms, such as visual disturbances, headache, and hypopituitarism. Differential diagnosis is usually accomplished by neuroradiologic studies, even though in selected cases positron emission tomography and/or single photon emission tomography may aid to distinguish pituitary adenomas from other endocrine inactive lesions, such as meningiomas and craniopharyngiomas. Surgical management is usually considered the first choice treatment for patients with endocrine inactive pituitary adenomas because it is very effective in ameliorating symptoms of chiasmal compression and headache. Radical removal of the tumor, however, is difficult to obtain because of the frequent invasiveness into the cavernous sinus. Radiation therapy diminishes the likelihood of tumor recurrence, especially in patients with demonstrable tumor remnants after surgery. Medical therapy with dopaminergic drugs, somatostatin analogs, or gonadotropin-releasing hormone agonists or antagonists causes mild reduction of tumor size in few patients and, therefore, seems to be of limited value in the therapeutic management of patients with endocrine inactive pituitary adenomas.

Abstract
We report a unique case of a 28-yr-old woman with a gonadotroph adenoma secreting FSH, presented with ovarian hyperstimulation, without elevation of serum estradiol. She presented with abdominal pain and large ovaries (both 10 cm in diameter) with multiple follicular cysts shortly after discontinuing oral contraceptive pills. She had a supranormal PRL level of 71 microg/liter (normal, <20), FSH of 8.4-9.2 IU/liter (normal for follicular phase, 2.4-10), LH of 0.01 IU/liter (normal, 1.6-9.3), estradiol of 108 pmol/liter (normal for follicular phase, 80-790), and free alpha-subunit level of 0.11 microg/liter (normal, <1.8). A nuclear magnetic resonance study revealed invasive pituitary macroadenoma, 30 mm in diameter. Dopamine agonist (cabergoline) treatment normalized serum PRL but had no affect on FSH levels. A transsphenoidal surgery was performed, and most of the adenoma was resected. One month after surgery the patient resumed menstruation, and the hormonal profile included serum FSH of 6.3 IU/liter, LH of 2.1 IU/liter, estradiol of 156 pmol/liter, and PRL of 10 microg/liter. The excised adenoma tissue exhibited intense immunostaining for FSH and secreted this hormone to culture medium. Stimulation with TRH (both in vivo preoperatively and in vitro study of the excised tumor) had no effect on FSH secretion from the adenoma. Estradiol did not suppress FSH release from cultured adenoma cells. Patient serum samples showed significant FSH bioactivity when tested in a human granulosa cell line. This case is remarkable because the ovarian hyperstimulation related to the FSH-secreting adenoma was not associated with high levels of serum estradiol, probably due to insufficient LH production by the normal pituitary. Thus, it supports the two-cell, two-gonadotropin theory, that both FSH and LH are necessary for normal ovarian estrogen production.
