The objective of this study was to expand the data on menstrual cycle serum hormone patterns in female common chimpanzees, both in terms of the number of cycles analyzed and by the addition of data on testosterone levels. Samples were obtained from 11 unanesthetized animals trained for conscious blood withdrawal. LH, FSH, 17β-estradiol (E2), progesterone (P), and testosterone (T) were measured by radioimmunoassay, genital swelling was recorded, and menstrual blood was noted. Concurrent midcycle elevations in LH and FSH and luteal phase elevations in progesterone suggested that the cycles were ovulatory. Detumescence of genital swelling occurred about 3 days after the midcycle LH peak, 1 day after the luteal phase nadir in E2, and 1 day after P levels exceeded 5 ng/ml. These relationships provide further support for the use of genital swelling in monitoring progress of the menstrual cycle. The hormone patterns in the chimpanzees closely resembled those of the human females, but E2 and T levels were higher. The levels of E2 and T were higher and the midcycle elevation in T was broader in the chimpanzee than in gorillas and orangutans. This is of interest because E2 and T are implicated in the regulation of mating, and chimpanzees mate over a greater portion of the cycle than the other apes. These data indicate the need for further study of hormonal contributions to the different patterns of mating in the great apes. They also support the use of the female common chimpanzee as a model for the human female in endocrine studies of the menstrual cycle. 相似文献

Forty-four female cynomolgus macaques (Macaca fascicularis) were examined to determine the optimum fertile period for mating. Daily urinary estrone conjugates (E1C) were measured, beginning on day 7 of the menstrual cycle, until a 1.5-gold E1C rise above the baseline was detected. The females were bred the next morning. Pregnancies were verified in all animals at day 18 postbreeding, and/or on day 25 postbreeding. Serum progesterone levels were used to correlate the relationship between ovulation and the E1C peak. Forty-four of the 57 cycles indicated a urinary E1C peak between days 10-15 of the menstrual cycle; this peak occurred on the day following the initial 1.5-fold to twofold rise in 90% of the cycles. A single 2-hr mating period the day before, the day of, or the day after the E1C peak resulted in conception in 17 of 44 (38.6%) animals. 相似文献

To determine the effects of a human oral contraceptive on normal and abnormal reproductive endocrine patterns in two lowland gorillas (Gorilla gorilla), daily urine samples were analyzed by radioimmunoassay for estrone conjugates (EC) and pregnanediol-3-glucuronide (PdG). During a pre-treatment period one female (F1) demonstrated regular menstrual cycles averaging 27.6 ± 1.8 days, whereas ovarian cyclicity in female 2 (F2) was consistently prolonged, ranging from 37–51 days. A 56 day regimen of an oral contraceptive (Demulen 50®) was administered to both females beginning in the late luteal phase, and within 6 and 7 days of treatment onset (F1 and F2, respectively) urinary EC and PdG declined to and remained at concentrations consistent with amenorrhea throughout the administration period. Ten and twenty days after contraceptive withdrawal (F1 and F2, respectively) an EC peak was observed with subsequent PdG elevations 1–2 days later. Mean cycle length and luteal phase durations were not different (P > 0.05) before or after treatment for either female, while combined peak PdG concentrations were greater (P < 0.05) for the first 3 months after treatment compared to pre-treatment values. These results indicate that a human oral contraceptive rapidly suppresses ovarian activity in female lowland gorillas, but that the abnormal endocrine pattern observed in F2 could not be redirected into a normal profile after contraceptive withdrawal. © 1992 Wiley-Liss Inc. 相似文献

Although endogenous and exogenous steroid hormones affect numerous physiological processes, the interactions of reproductive hormones, chronic exercise training, and heat acclimation are unknown. This investigation evaluated the responses and adaptations of 36 inactive females [age 21 +/- 3 (SD) yr] as they undertook a 7- to 8-wk program [heat acclimation and physical training (HAPT)] of indoor heat acclimation (90 min/day, 3 days/wk) and outdoor physical training (3 days/wk) while using either an oral estradiol-progestin contraceptive (ORAL, n = 15), a contraceptive injection of depot medroxyprogesterone acetate (DEPO, n = 7), or no contraceptive (EU-OV, n = 14; control). Standardized physical fitness and exercise-heat tolerance tests (36.5 degrees C, 37% relative humidity), administered before and after HAPT, demonstrated that the three subject groups successfully (P < 0.05) acclimated to heat (i.e., rectal temperature, heart rate) and improved muscular endurance (i.e., sit-ups, push-ups, 4.6-km run time) and body composition characteristics. The stress of HAPT did not disrupt the menstrual cycle length/phase characteristics, ovulation, or plasma hormone concentrations of EU-OV. No between-group differences (P > 0.05) existed for rectal and skin temperatures or metabolic, cardiorespiratory, muscular endurance, or body composition variables. A significant difference post-HAPT in the onset temperature of local sweating, ORAL (37.2 +/- 0.4 degrees C) vs. DEPO (37.7 +/- 0.2 degrees C), suggested that steroid hormones influenced this adaptation. In summary, virtually all adaptations of ORAL and DEPO were similar to EU-OV, suggesting that exogenous reproductive hormones neither enhanced nor impaired the ability of women to complete 7-8 wk of strenuous physical training and heat acclimation. 相似文献

The socio-sexual environment of a female is known to affect ovarian function. Increased male contact can enhance menstrual cycle regularity. Conversely, social deprivation constitutes a form of stress that often alters cyclicity and the secretion of reproductive hormones. The present study was carried out on captive female chimpanzees to examine possible interactions among housing conditions, menstrual cycle length, morphological changes in secondary sexual character expression and endocrine release patterns related to follicular and luteal function. Animals were housed over a period of 2 years either with a male conspecific or singly. Blood samples were collected over three cycles, and anogenital swelling changes registered to define menstrual cycle phases. Fecal sampling techniques were used to monitor cortisol as a measure of stress-load. Male presence seemed to affect female cyclicity. Females housed with a male had shorter and more regular cycles than singly housed females. Prolactin, gonadotropins and estradiol levels were generally higher in paired females during specific cycle phases. Group variation was not always significant. No differences were found in progesterone. Sexually cohabited females tended to have lower fecal cortisol metabolites immediately before and after maximum tumescence. We suggest that the close behavioral, physical and olfactory contact with a male conspecific can act as a sort of zeitgeber to modulate ovarian function by stabilizing the female cycle and, perhaps, enhancing folliculogenesis and ovulation. 相似文献

Urinary steroid hormones and luteinizing hormone (LH) were monitored in a female pileated gibbon. The LH concentration almost peaked the day after estrogens peaks. The progesterone increased sharply after the LH peaks. Our results revealed for the first time the relationship between daily changes in urinary hormones throughout normal menstrual cycles in pileated gibbon. 相似文献

Influence of acute tryptophan depletion on verbal declarative episodic memory in young adult females
K. Helmbold S. Bubenzer B. Dahmen A. Eisert T. J. Gaber U. Habel K. Konrad B. Herpertz-Dahlmann F. D. Zepf 《Amino acids》2013,45(5):1207-1219
Diminished synthesis of the neurotransmitter serotonin (5-HT) in the brain has been linked to disturbed memory processes. The present study investigated the effects of diminished central nervous 5-HT synthesis as achieved by an acute dietary tryptophan depletion (ATD) on verbal declarative episodic memory in young women while controlling for the effects of female sex hormones. Eighteen healthy females (aged 20–31 years) participated in a within-subject repeated measures study, with two separate days of assessment spaced at least one individual menstrual cycle apart. On one day, participants were subjected to ATD, thus lowering central nervous 5-HT synthesis. The other day participants received a tryptophan-balanced amino acid load (BAL = control condition). The study was randomized, counterbalanced and double blind in terms of ATD/BAL administration. Measurements took place in the early follicular phase of the participants’ menstrual cycle. Estrogen, FSH and LH levels were assessed at baseline. Verbal declarative episodic memory was assessed using a structured word-learning task. Short-term memory, as indexed by immediate recall, was reduced after ATD intake, whereas delayed recall and recognition after a 25-min delay did not show any differences after intake of ATD or BAL. In young women, verbal short-term memory function was more vulnerable to ATD than consolidation processes. In light of the possible interplay between female sex hormones and 5-HT, further studies comparing different menstrual cycle phases are needed. 相似文献

Periovulatory changes in female sexual behavior and patterns of ovarian steroid secretion in group-living rhesus monkeys 总被引:1,自引:1,他引:0
Kim Wallen Linda A. Winston Suzanne Gaventa Maryann Davis-DaSilva Delwood C. Collins 《Hormones and behavior》1984,18(4):431-450
The behavior of nine intact group-living adult female rhesus was observed for 30 min daily with each of four adult male rhesus across a verified ovulatory menstrual cycle. Blood samples collected from females daily or on alternate days were analyzed for estradiol, testosterone, and progesterone. Female patterns of approach, follow, and initiate proximity increased several days prior to the estradiol peak, peaked on the day of the estradiol peak, then declined completely or to very low frequencies. Mounts, intromissions, and ejaculations increased significantly on the day of the estradiol peak, remained elevated for 2 more days, then declined completely by the fifth day after peak estradiol. Ejaculations never occurred outside of a 10-day period starting 4 days before the estradiol peak and ending 5 days after the estradiol peak. During this period females initiated over 90% of all approaches. Female hand slap, threaten away, and stand up increased significantly on the first day of increased copulation, remained elevated while copulation was significantly elevated, then decreased along with the decline in copulation. Ten of eleven patterns of female behavior correlated significantly with estradiol level prior to the estradiol peak. All were significantly inversely correlated with progesterone level after the estradiol peak. No pattern of female behavior correlated significantly with testosterone either before or after the estradiol peak. Similarly, male patterns of behavior correlated with female levels of estradiol and progesterone, but not testosterone. These results demonstrate a relationship between increased serum estradiol and increased female initiation of sexual behavior. The finding that some patterns of female behavior increase several days prior to copulation, whereas other behaviors increase coincident with increased copulation suggests that the behavior of group-living rhesus females serves two functions. The first is to communicate sexual interest and the second is to maintain the consort pair and increase the probability that ejaculation will occur. In addition, the strong correlation between preovulatory female behavior and estradiol level suggests that the female's behavior provides precise information about her reproductive state and could thus coordinate copulation with maximal fertility. 相似文献

The amount of estradiol and progesterone in the systemic blood plasma of six adult female Japanese monkeys was measured by
radioimmunoassay. Data on heterosexual pairing tests was also collected and examined for correlation with these hormones.
The relationship between ovarian hormones and frequency of ejaculation varied with each female. In nine normal menstrual cycles,
the frequencies of invitation and approach by the female reached peaks on the day of the estradiol surge, after which they
rapidly decreased. Frequencies of male behaviors including approach, leaving, invitation, and yawning significantly decreased
during the luteal phase, as compared with those at the midcycle. Grooming by both sexes of the partner reached low points
during the late follicular phase. The number of ejaculations per test increased significantly at the midcycle and reached
a maximum a few days after the estradiol surge. The present results suggest that female proceptivity is highly correlated
with the amount of estradiol, but her attractiveness is little correlated with estradiol and is lowered by progesterone. 相似文献

In order to clarify the relationship between exercise and neutrophil function, we measured three major neutrophil and neutrophil-related functions, viz. the reactive oxygen species (ROS) production capability and phagocytic activity (PA) of neutrophils and serum opsonic activity (SOA), simultaneously before and after a unified loading exercise under three different sets of conditions. Thirteen female collegiate judoists were examined with a unified exercise loading (2 h) immediately before and after a 64 day training period. Immediately thereafter, the athletes took part in a 6 day intensified training camp, following which the same exercise loading was repeated. Responses from circulating neutrophils were estimated by comparing the two sets of values obtained before and after the two instances of exercise loading. The parameters assessed included neutrophil count, SOA, PA and ROS production capability. ROS production increased after the exercise loading performed immediately before and after the 64 day training period just before the camp, (p < 0.01) but decreased following the exercise loading performed after the camp (p < 0.05). This suggested depressed bacteriocidal capability of the circulating neutrophils. PA decreased after the exercise loading sessions imposed prior to and after the 64 day training period (p < 0.01) but did not change in the loading session after the camp. No changes were seen in SOA produced with the loading exercise either before the 64 day exercise period or before the camp, but increased significantly following the post-camp session (p < 0.05). In conclusion, athletic training-induced changes in immune functional activities of neutrophils, such as ROS production and PA, and neutrophil-related factors, such as SOA, may compensate for each other to maintain the overall integrity of the neutrophil immune function. 相似文献
