1. Comparação da composição alimentar e do consumo alcoólico entre a fase folicular e a fase lútea tardia de mulheres dependentes de álcool / Comparison of food composition and alcohol consumption between follicular phase and late luteal phase in alcohol dependent women
A fase lútea tardia (FLT) é citada pela literatura como crítica para exacerbação de todos os transtornos psiquiátricos, o que pode significar maior consumo alcoólico por indivíduos dependentes e risco de recaídas para aqueles abstinentes. Paralelamente, é freqüente o relato clínico de aumento do consumo alimentar nesta fase. Conter a compulsivida

2. Endometrial protein expression during the luteal phase of the menstrual cycle / Expressão protéica no endométrio durante a fase lútea do ciclo menstrual
Introduction: The objective of this study was to evaluate endometrial protein expressions from fertile and infertile women during the luteal phase of the menstrual cycle by immunohistochemistry in tissue microarrays (TMA). Method: The expression of ten proteins obtained from 52 endometrial samples in the initial, mid (window of implantation) and late (premen

3. Effects of metformin treatment on luteal phase progesterone concentration in polycystic ovary syndrome
The causes of luteal phase progesterone deficiency in polycystic ovary syndrome (PCOS) are not known. To determine the possible involvement of hyperinsulinemia in luteal phase progesterone deficiency in women with PCOS, we examined the relationship between progesterone, luteinizing hormone (LH) and insulin during the luteal phase and studied the effect of me

4. Role of estradiol on bovine luteolysis: estradiol stimulates PGF2&alpha througthout P4 receptor activation in the endometrium? / As funções do estradiol no processo da luteólise em bovinos: o estradiol estimula PGF2α através da ativação de receptores de P4 no endométrio?
Estradiol (E2) is essential for triggering luteolysis in ruminants. The low E2 concentrations after follicular ablation prolongs luteolysis instead of E2 injections in late luteal phase stimulate prostaglandin F2α (PGF2α) and luteolysis. The E2 could act in endometrium avoiding progesterone (P4 ) to stimulate PGF 2α secretion. A P4 antagoni

5. Neuroendocrine regulation of the corpus luteum in the human. Evidence for pulsatile progesterone secretion.
The pattern of episodic gonadotropin release was studied in 15 normal female volunteers during the luteal phase of the menstrual cycle with 24 h of blood sampling for follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels at 10-min intervals. Six subjects (two in the early, two in the mid-, and two in the late luteal phase) also had each of t

6. The effects of superior ovarian nerve sectioning on ovulation in the guinea pig
The effects on spontaneous ovulation associated with the unilateral or bilateral sectioning of the superior ovarian nerves (SON) were analyzed in guinea pigs at different time intervals of the estrous cycle. Day 1 of the estrous cycle was defined as the day when the animal presents complete loss of the vaginal membrane (open vagina). Subsequent phases of the

7. Female body odour is a potential cue to ovulation.
Human body odours have been reported to influence female mate choice. Women prefer the odours of immunocompatible men and, during their fertile period, judge the body odours of men with symmetrical bodies--which is indicative of genetic quality--as sexy and pleasant. The reproductive success of men largely depends on mating with fertile women, but it is not

8. Cyclical secretion of prorenin during the menstrual cycle: synchronization with luteinizing hormone and progesterone.
Plasma prorenin, a high molecular weight precursor form of renin, (renin, EC 3.4.23.15; old number, EC 3.4.99.19), was measured three times weekly in normal young women during the menstrual cycle and was related to changes in luteinizing hormone, estradiol, and progesterone. In all subjects a stable baseline level of prorenin occurred during the follicular p

9. Decreased release of gonadotropin-releasing hormone during the preovulatory midcycle luteinizing hormone surge in normal women.
To investigate the contribution of hypothalamic gonadotropin-releasing hormone (GnRH) secretion to the midcycle gonadotropin surge in the human, the response of luteinizing hormone (LH) to competitive GnRH receptor blockade achieved by administration of a range of doses of a pure GnRH antagonist was used to provide a semiquantitative estimate of endogenous G

10. Electron microscopic studies on the endometrium of the grey seal (Halichoerus grypus) during its preparation for nidation.
The uterine luminal and glandular epithelia of two mature grey seals, a species with obligate delayed implantation, have been examined. Earlier studies of their corpora lutea had suggested that these females were in the pre-nidatory condition. Ultrastructural features of these epithelia in the animal which possessed the more mature corpus luteum indicated th

11. Investigation of the efficacy of progesterone pessaries in the relief of symptoms of premenstrual syndrome. progesterone Study Group.
BACKGROUND. A variety of definitions have been applied to premenstrual syndrome. The severity of the syndrome is also variable. AIM. A study was undertaken to compare progesterone pessaries with placebo in the relief of symptoms of premenstrual syndrome. In this study the condition was characterized by a wide range of symptoms recurring in the late luteal ph

12. Selective serotonin reuptake inhibitors directly alter activity of neurosteroidogenic enzymes
The neurosteroid 3α-hydroxysteroid-5α-pregnan-20-one (allopregnanolone) acts as a positive allosteric modulator of γ-aminobutyric acid at γ-aminobutyric acid type A receptors and hence is a powerful anxiolytic, anticonvulsant, and anesthetic agent. Allopregnanolone is synthesized from progesterone by reduction to 5α-dihydroprogesterone, mediated by 5α-
