Trigonella foenum-graecum L. (fenugreek, TFG) and Asparagus racemosus Willd. (shatavari, AR) have been extensively used in Ayurvedic, Unani, and traditional folk medicine to support women’s health. TFG seeds are traditionally employed as galactagogues and hormonal modulators, while AR roots are valued as rejuvenating tonics with phytoestrogenic activity, prescribed for menopausal complaints and reproductive well-being. Both plants also exhibit antioxidant and hepatoprotective effects, suggesting their potential as safe, nonhormonal alternatives to conventional hormone replacement therapy. This study investigated the dose-dependent effects of TFG and AR, administered individually or in combination, on vasomotor symptoms, hormonal balance, oxidative stress, and neuroendocrine markers in an ovariectomized (OVX) rat model of menopause. Adult female rats underwent bilateral ovariectomy and were randomized into eight groups: Control, OVX, OVX+TFG (30 and 60 mg/kg), OVX+AR (30 and 60 mg/kg), and OVX+TFG/AR combinations. Treatments were administered orally for 8 days. Tail, core, and skin temperatures were recorded to assess thermoregulation, while blood and tissue samples were analyzed for hormone levels, oxidative stress, and molecular markers. OVX rats showed classical menopausal alterations, including increased follicle-stimulating hormone, luteinizing hormone, cortisol, and malondialdehyde, and decreased 17β-estradiol, progesterone, dopamine, and antioxidant enzymes, along with dysregulated neuroendocrine markers. All treatments partially reversed these changes, while the high-dose combination (TFG/AR 60 mg/kg each) demonstrated the most pronounced effects, normalizing hormone levels, reducing hot-flash-like temperature fluctuations, restoring antioxidant activity, downregulating neuroendocrine markers (c-FOS, GnRH, Kisspeptin, NKB, and TRPV1) expression, and elevating brain-derived neurotrophic factor levels (p < 0.05). High-dose combined supplementation of TFG and AR effectively alleviates vasomotor disturbances, restores hormonal and oxidative balance, and modulates neuroendocrine pathways in OVX rats. These findings validate their traditional use and highlight their potential as safe phytoestrogen-based, nonhormonal alternatives for the management of menopausal symptoms, warranting further clinical evaluation.

Remodeling of the extracellular matrix (ECM) throughout the estrous cycle is one of the most striking features of the uterus. A disintegrin and metalloprotease with thrombospondin type I motifs (ADAMTS-1) is a metalloproteinase responsible for the degradation of some proteoglycans, which are ECM components. In this study, ADAMTS-1 distribution was analyzed in the uterus of ovariectomized rats administered 17β-estradiol (E2) and progesterone (P4) and in the uterus at different estrous stages. Ovariectomized (OVX) rats were subjected to single and combined E2 (0.2 mg/kg) and P4 (10 mg/kg) hormone replacement therapies. E2 was administered for 3 consecutive days, followed by E2, P4, or E2 + P4 for 4 consecutive days. The serum level of E2 decreased from the proestrus phase to the diestrus phase, but that of P4 was the highest in the estrus phase. During the estrus phase, the serum level of luteinizing hormone (LH) was the lowest and that of follicle-stimulating hormone (FSH) was the highest. P4 level increased significantly in the OVX + P4 and OVX + E2 + P4 groups compared with the OVX group. The serum levels of LH and FSH decreased in the OVX + E2 and OVX + P4 groups compared with the OVX group, and were the lowest in the OVX + E2 + P4 group. ADAMTS-1 immunoreactivity in luminal, glandular, and stromal cells of the uterus decreased from proestrus to diestrus. When immunoreactivity in hormone replacement groups was compared, weak immunoreactivity was observed in the OVX group. ADAMTS-1 immunoreactivity gradually increased in OVX + P4 and OVX + E2 groups, and was particularly notable in luminal, glandular, and stromal cells in the OVX + E2 + P4 group. ADAMTS-1 distribution was affected by the estrous cycle process and hormone replacement therapy in the OVX procedure.

Vasomotor symptoms, such as hot flashes (HFs), commonly affect women during menopause, leading to a reduced quality of life. The current study evaluates the combined effect of active components Asparagus racemosus (AR) and Trigonella foenum-graecum (TFG) in a single oral formulation (IAT) for alleviating menopausal symptoms in ovariectomized rats. Following bilateral ovariectomy, the animals were randomly assigned to nine groups: (1) Control, (2) Ovariectomy (OVX), (3) OVX+TA1 (TA: Combination of Trigonella and Asparagus; TFG 30 mg/kg + AR 30 mg/kg), (4) OVX+TA2 (TFG 30 mg/kg + AR 15 mg/kg), (5) OVX+TA3 (TFG 15 mg/kg + AR 30 mg/kg), (6) OVX+TA4 (TFG 40 mg/kg + AR 30 mg/kg), (7) OVX+TA5 (TFG 30 mg/kg + AR 40 mg/kg), (8) OVX+IAT1 (IAT: Integrated Asparagus and Trigonella; TFG+AR integrated extract, 30 mg/kg), and (9) OVX+IAT2 (TFG+AR integrated extract, 60 mg/kg). On the 8th day of treatment, tail and skin temperatures were recorded every 30 min for 24 h. Ovariectomized rats exhibited menopausal symptoms, such as hormonal imbalances and elevated skin temperature. Administration of AR, TFG, and IAT significantly decreased serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), and cortisol while increasing estradiol, progesterone, and dopamine (p < 0.0001), effectively alleviating hot flash-like symptoms. Additionally, they mitigated ovariectomy-induced oxidative stress by lowering malondialdehyde (MDA) levels and restoring antioxidant enzyme activity. Ovariectomized rats exhibited increased expression of a proto-oncogene (c-FOS), gonadotropin-releasing hormone (GnRH), Kisspeptin, Neurokinin B (NKB), and Transient receptor potential vanilloid 1 (TRPV1), along with reduced expressing brain-derived neurotrophic factor (BDNF) levels, which were reversed by treatment, especially with the IAT2 combination. The AR and TFG combination, particularly in IAT formulations, showed strong potential in alleviating menopausal symptoms in ovariectomized rats. These findings suggest that the combination of AR and TFG extracts could be a natural alternative for managing postmenopausal symptoms by restoring reproductive hormone levels, regulating lipid profiles, and enhancing antioxidant defense systems.
