background: pyrethroids are commonly used as insecticides for both household and agricultural applications, and have recently been linked to endocrine disruption. cypermethrin is a type п pyrethroid which is used widely throughout the world. the present study was aimed to investigate the effects of cypermethrin on the sexual behaviour and plasma level of pituitary-gonadal hormones of adult male...

To investigate a possible correlation between sexual hormonal status and the presence of female sexual dysfunction (FSD) using the Female Sexual Function Index (FSFI) in females with spinal cord injuries (SCI), we selected 39 SCI fertile-aged women. At visit 1, we assessed the presence of FSD using the FSFI, and all individuals were submitted to a blood hormone evaluation on the third day of th...

OBJECTIVE To examine the relationship between reproductive hormonal dynamics and sexual dysfunction assessed in a cohort of women approaching menopause. METHODS Women in the Penn Ovarian Aging Study were assessed at yearly intervals for 3 years with early follicular hormone measurements (estradiol, follicle-stimulating hormone, luteinizing hormone [LH], sex hormone binding globulin, dehyroepi...

The r6le of specific sexual hormones in the sexual reaction of two hetero-thallic species of Achlya has been described in earlier papers of this series.' Four specific substances were postulated, two secreted by the 9, bringing about specific reactions in the e, and two secreted by the c, inducing specific responses in the 9. On the basis of evidence available at that time it seemed that the en...

The frequency of female sexual dysfunction increases with age, and the menopausal transition has a negative effect on the sexuality. Pharmacological treatment options for female sexual dysfunction during the peri- and post-menopause include hormone therapy or sildenafil. A limited number of randomized, controlled trials have been conducted and evidence suggests that systemic hormone therapy wit...

A Phytophthora mating hormone with an array of 1,5-stereogenic centers has been synthesized by using our recently developed methodology of catalytic enantioselective conjugate addition of Grignard reagents. We applied this methodology in a diastereo- and enantioselective iterative route and obtained two of the 16 possible stereoisomers of Phytophthora hormone alpha1. These synthetic stereoisome...

The aim of this study was to review the effect of estrogen on growth hormone secretion and the roles of estrogen and growth hormone in reproductive function. Estrogen is the main hormone affecting growth, development, maturation and functioning of reproductive tract as well as the sexual differentiation and the behavior. Growth hormone is also important factor in sexual maturation and attainmen...

Objective: To investigate a possible correlation between sexual hormonal status and presence of female sexual dysfunctions (FSD) through the Female Sexual Function Index (FSFI) in females with spinal cord injuries (SCI). Methods: We selected 39 SCI fertile-aged women. At visit 1 we assessed the 5 presence of FSD using the FSFI and all individuals were submitted to a haematic hormonal evaluation...
