This study observed that the reproductive phenology of Ficus species in Northern Thailand varied seasonally, with female trees producing the most figs during the rainy season, while male trees' fig production peaked earlier.

This article discusses the potential benefits of platelet-rich plasma injections in ovarian tissue to improve reproductive outcomes in IVF for older individuals and proposes a mechanism to enhance embryo ploidy rescue, but reports no new clinical results.

This review analyzes how androgens impact sexual desire and reproductive behaviors, emphasizing molecular interactions, but provides no new clinical results.

In this study, laparoscopic ovarian diathermy with three to five punctures per ovary improved reproductive outcomes for women with clomiphene-resistant polycystic ovary syndrome, while more than six punctures may cause excessive ovarian damage.

This chapter discusses the role of hormones in regulating reproductive biology and outlines how the endocrine system, particularly the brain and pituitary gland, controls these hormonal processes.

The document concludes that sex hormones are crucial for mammalian reproduction, health, and behavior, and require more research for therapeutic use.

This study found that L-glutamine supplementation in Hanwoo steers under heat stress did not affect growth performance or muscle and adipose tissue gene expression but was associated with increased immune cells and reduced HSP90 expression.

This research reports that essential oils may enhance athletic performance by improving cerebral hemodynamics and promoting muscle and psycho-emotional relaxation through activation of the limbic system.

This study found that while the carboplatin-paclitaxel regimen for advanced lung cancer is more affordable than newer treatments and maintains a good performance status, it significantly increases risks of alopecia and peripheral neuropathy.

This study observed that tributyltin pollution induces imposex, reduces reproductive success, and leads to population decline in Ocinebrina aciculata, highlighting its sensitivity compared to other prosobranch species.

This study found that obesity in women may impair endometrial stromal function and contribute to reproductive complications, possibly due to metabolic influences rather than immune cell differences.
