“…These events make the hypothalamic-pituitary-ovarian axis pivotal in eumenorrhea. Alterations in this axis can induce changes in essential female sex hormones, including oestradiol and progesterone (Seyed Saadat et al, 2016). Fluctuations in female sex hormone levels throughout the menstrual cycle can affect neuromuscular function (Ansdell et al, 2019).…”

“…During the early follicular phase, females lose approximately 50-150 ml of blood containing tissue fluids, mucus, and epithelial cells (Tortora & Derrickson, 2017) shed from the endometrium. Subsequently, oestradiol and progesterone concentrations decrease, whereas prostaglandin levels rise (Seyed Saadat et al, 2016). Female athletes experience fatigue, wide mood swings, and energy deficits during training (Klentrou & Plyley, 2003;Romero-Moraleda et al, 2019).…”

This study investigated the acute effects of caffeine intake on sex hormones (follicle-stimulating hormone, luteinizing hormone, prolactin, oestradiol, and progesterone) following resistance exercise performance during the early follicular phase. In addition, the total number of failed repetitions was determined. Ten resistance-trained females performed two consecutive trials (48 h apart). Participants were randomly assigned to receive either caffeine (4 mg/kg) 1 h before exercise or a placebo, using a double-blind crossover design. Each trial included the following resistance exercises: chest press, lat pulldown, triceps pushdown, and rowing torso. Each exercise was performed in three sets of 10 repetitions at 60% of 1-RM, with a 90 s recovery interval, followed by repetitions to failure at the same intensity during the fourth set. Two-minute breaks were allocated between each exercise's third and fourth sets of and between exercises. Blood samples were collected from each participant 1 h after the completion of each trial. Data revealed no statistical difference (p ˃ .05) in ergogenic response to caffeine on sex hormones during the early follicular phase between trials. However, serum prolactin level significantly decreased (p = .039) after caffeine intake compared to the placebo. The overall repetitions to failure were significantly higher (p = .023) in the caffeine trial than in the placebo. In conclusion, caffeine intake (4 mg/kg) 1 h before multiple resistance exercises had no effect on sex hormone responses during the early follicular phase, except for prolactin. However, the overall repetitions until failure were higher following caffeine intake.

Objective: Exercise is a risk factor for infertility in women. However, research on the effects of different intensities of exercise on folliculogenesis has not yielded clear results. This study was conducted to analyze the effects of differences in the intensity of exercise on folliculogenesis in mice. Methods: Nineteen female BALB/c mice (age, 3–4 months; weight, 13–25 g) were randomly divided into four groups: control, mild exercise, moderate exercise, and high-intensity exercise. The mice in the exercise groups engaged in swimming, with additional loads of 3%, 6%, or 9% of body weight, respectively. There were five swimming sessions per week for 4 weeks, with a gradually increasing duration every week. At the end of the treatment, ovarian extraction was carried out and hematoxylin and eosin staining was performed to identify folliculogenesis. Results: There were significant differences in the number of total follicles between the control and moderate-exercise groups (p=0.036) and between the mild- and moderate-exercise groups (p=0.005). The mean number of primary follicles was higher in the moderate-exercise group than in the mild-exercise group (p=0.006). The mean number of secondary, tertiary, and Graafian follicles did not differ significantly among groups (p≥0.05). However, the number of total follicles and follicles in each phase tended to increase after exercise, especially moderate-intensity exercise. Conclusion: Exercise of different intensities affected the total number of follicles and primary follicles. The number of follicles of each phase tended to increase after exercise. Moderate-intensity exercise had better effects than other intensities of exercise.
