Exploring natural herbs: their role in treating male infertility, enhancing sexual desire and addressing urological disorders

Infertility affects 8-12% of couples globally, with male factors contributing to around 40% of cases. Common male infertility issues include erectile dysfunction (ED) and low sperm count or quality, which account for over 90% of cases. These problems often result from anatomical, hormonal, or genetic abnormalities. This review focuses on natural aphrodisiac herbs commonly used to address ED, providing detailed information on their botanical characteristics, metabolic pathways, recommended dosages, phytochemical properties, side effects, origins, and traditional uses. It also reviews recent studies on medicinal herbs that boost sexual desire and treat urological conditions. By compiling reliable findings from the past decade, the study aims to serve as a comprehensive resource for individuals dealing with sexual health issues. Through careful evaluation of each herb, it offers insights into their effectiveness and limitations, emphasizing the potential of natural treatments as complementary alternatives to conventional therapies for male infertility and related conditions.

Antibacterial and Antibiofilm Effects of Different Samples of Five Commercially Available Essential Oils

Essential oils (EOs) have gained economic importance due to their biological activities, and increasing amounts are demanded everywhere. However, substantial differences between the same essential oil samples from different suppliers are reported-concerning their chemical composition and bioactivities-due to numerous companies involved in EOs production and the continuous development of online sales. The present study investigates the antibacterial and antibiofilm activities of two to four samples of five commercially available essential oils (Oregano, Eucalyptus, Rosemary, Clove, and Peppermint oils) produced by autochthonous companies. The manufacturers provided all EOs' chemical compositions determined through GC-MS. The EOs' bioactivities were investigated in vitro against Gram-positive (Staphylococcus aureus) and Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa). The antibacterial and antibiofilm effects (ABE% and, respectively, ABfE%) were evaluated spectrophotometrically at 562 and 570 nm using microplate cultivation techniques. The essential oils' calculated parameters were compared with those of three standard broad-spectrum antibiotics: Amoxicillin/Clavulanic acid, Gentamycin, and Streptomycin. The results showed that at the first dilution (D1 = 25 mg/mL), all EOs exhibited antibacterial and antibiofilm activity against all Gram-positive and Gram-negative bacteria tested, and MIC value > 25 mg/mL. Generally, both effects progressively decreased from D1 to D3. Only EOs with a considerable content of highly active metabolites revealed insignificant differences. E. coli showed the lowest susceptibility to all commercially available essential oils-15 EO samples had undetected antibacterial and antibiofilm effects at D2 and D3. Peppermint and Clove oils recorded the most significant differences regarding chemical composition and antibacterial/antibiofilm activities. All registered differences could be due to different places for harvesting the raw plant material, various technological processes through which these essential oils were obtained, the preservation conditions, and complex interactions between constituents.
