Abstract

Reproductive and urogenital pharmacology encompasses the pharmacological basis of therapies that target reproductive endocrinology, fertility modulation, sexual function, and lower urinary tract disorders. The field integrates hormonal regulation with drug discovery, addressing both male and female reproductive health. Hormonal contraceptives remain a cornerstone of family planning, involving estrogen-progestin combinations and progestin-only formulations, each with distinct mechanisms and risk-benefit profiles. Fertility treatments, including ovulation induction with clomiphene and gonadotropins, have advanced assisted reproductive technologies but pose complications such as ovarian hyperstimulation syndrome (OHSS). Androgen modulators such as testosterone therapy, anti-androgens, and 5α-reductase inhibitors play critical roles in conditions like hypogonadism, prostate cancer, and polycystic ovary syndrome (PCOS). Hormone replacement therapy (HRT) during menopause continues to raise debate over cardiovascular risks and cancer incidence, necessitating individualized approaches. Pharmacological interventions for benign prostatic hyperplasia (BPH), erectile dysfunction, and urinary incontinence highlight the relevance of α-blockers, phosphodiesterase-5 inhibitors, β3 agonists, and intravesical botulinum toxin. Finally, drug safety in pregnancy and lactation remains paramount, as teratogenic risks and FDA classifications guide therapeutic decision-making. This chapter provides…
