Evidence suggests that the gonadal steroids may exert clinically significant effects on central nervous system function. For example, the menstrual cycle may influence the occurrence of seizures in some female epileptics and the performance on certain cognitive tests. Central nervous system effects of gonadal steroids have been inferred largely from changes in behavior occurring in association with presumed changes in gonadal steroids during the normal menstrual cycle, during the administration of ovarian hormones, or in a gender-specific context. These inferences are, by definition, indirect and associational in nature and further are incapable of disentangling the effects of hormones which are simultaneously present in women of reproductive age. This study is designed to address those problems by comparing measures during Lupron-induced hypogonadism with those during replacement with estrogen or progesterone. On the basis of prior findings from our group and from others, we will be asking the following questions: 1) Is the decreased r-CBF that we observed in the prefrontal cortex during the hypogonadal state confirmed in individual women using new imaging techniques; 2) Will variation in genotype (e.g., COMT val/met, BDNF val/met) confer differential sensitivity to ovarian steroids in brain circuitry and 3) Are the menstrual cycle phase-related changes in reward systems that we previously observed related to estradiol or progesterone actions within the brain (1). Additionally, this protocol will serve as a control study for protocol # 90-M-0088.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details

100 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Basic Science Study

Basic science studies help researchers understand how the body works or how a disease develops. They don't test treatments, but they build the foundation for future therapies.


Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.

Criteria

INCLUSION CRITERIA: Volunteers participating in this study will be women meeting the following criteria: Between the ages of 18 and 50 years, Not pregnant, In good medical health, Medication free, No history of menstrual-related mood or behavioral disturbances. Additionally, we will recruit a subsample of 20 asymptomatic women who will meet all inclusion and exclusion criteria in this protocol except they will have a history of a past major depressive episode. Finally, a third sample of 10 women who meet all the inclusion and exclusion criteria listed above for this protocol will be recruited to establish the dose range of transdermal estrogen gel for this and related protocols (i.e., 90-M-0088 and 05-M-0059). EXCLUSION CRITERIA: The following conditions will constitute contraindications to treatment with hormonal therapy and will preclude a subject's participation in this protocol: Current Axis I psychiatric diagnosis (with the exception of this women with a past major depression who will be studied on this protocol); History consistent with endometriosis; Diagnosis of ill-defined, obscure pelvic lesions, particularly undiagnosed ovarian enlargement; Hepatic disease as manifested by abnormal liver function tests; History of mammary carcinoma; History of pulmonary embolism or phlebothrombosis; Undiagnosed vaginal bleeding; Porphyria; Diabetes mellitus; History of malignant melanoma; Cholecystitis or pancreatitis; Cardiovascular or renal disease; Pregnancy; Any woman meeting the Stages of Reproductive Aging Workshop Criteria (STRAW) for the perimenopause (129). Specifically, we will exclude any woman with an elevated plasma follicle stimulating hormone (FSH) level (greater than or equal to 14 IU/L) and with menstrual cycle variability of > 7 days different from their normal cycle length. National Institute of Mental Health (NIMH) employees/staff and their immediate family members will be excluded from the study per NIMH policy. Subjects taking birth control pills will be excluded from the study. Subjects taking diuretics, prostaglandin inhibitors, or pyridoxine (putative treatments for MRMD) will similarly be excluded from the study, as will patients taking psychotropic agents (e.g., lithium carbonate, tricyclic antidepressants). All subjects will be required to use non-hormonal forms of birth control (e.g., barrier methods) to avoid pregnancy during this study. Participants who have an active condition that places them at an increased risk for osteoporosis will be excluded from this protocol.

Study Objectives

3 intervention groups are designated in this study

This study does not include a placebo group 

Treatment Groups

Group I

Experimental
Eight to 12 weeks of GnRH agonist treatment 3.75 mg given intramuscularly monthly.

Group II

Experimental
12 weeks of GnRH agonist treatment 3.75 mg given intramuscularly monthly. Additionally, 4 weeks of transdermal Estradiol (100mcg/day by skin patch) and placebo suppositories. Week 5 involves 100mcg/day transdermal Estradiol and active Progesterone suppositories (200mg vaginally twice/day). Followed by 1-2 weeks (weeks 6-7) washout period. Then crossover to 5 weeks (week 8-12) of Progesterone suppositories (200mg vaginally twice/day) and placebo patches.

Group III

Experimental
12 weeks of GnRH agonist treatment 3.75 mg given intramuscularly monthly. Additionally, 5 weeks of Progesterone suppositories (200mg vaginally twice/day) and placebo patches. Followed by 1-2 weeks (weeks 6-7) washout period. Then crossover to 4 weeks (weeks 8-11) of transdermal Estradiol (100mcg/day by skin patch) and placebo suppositories. Week 12 involves 100mcg/day transdermal Estradiol and active Progesterone suppositories (200mg vaginally twice/day).
