Prolonged testosterone 17β-cyclopentylpropionate exposition induces behavioral, ovarian, oviductal, uterine and reproductive disturbances in female mice. Life Sci 2024; 338:122408. [PMID: 38181852 DOI: 10.1016/j.lfs.2023.122408] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Revised: 12/16/2023] [Accepted: 12/29/2023] [Indexed: 01/07/2024]
Abstract
Anabolic-androgenic steroids (AAS) abuse is often associated with metabolic disorders and infertility. However, the current evidence on AAS-induced reproductive toxicity is mainly based on male studies. Thus, AAS repercussions on female reproductive capacity remain poorly understood, despite scarce evidence that fertility determinants may be more severely impaired in females than males exposed to these drugs. Accordingly, this study used an integrated framework to investigate the impact of different testosterone 17β-cyclopentylpropionate (TC) doses on pain sensitivity, aggressiveness, anxiety, sexual behavior, ovarian, oviductal, uterine and reproductive morphofunctional and molecular outcomes. These parameters were used to explore the reproductive capacity in female mice exposed to this synthetic testosterone ester. The animals were untreated or intraperitoneally treated with 5, 10 and 20 mg/kg TC every 48 h for 12 weeks. Our findings indicated that testosterone was upregulated while the hormones luteinizing, follicle-stimulating, estrogen and progesterone were down-regulated by TC. This AAS also exerted deleterious effects on anxiety, aggressivity, nociception, exploratory and sexual behavior in female mice. Concurrently, TC attenuated ovarian follicle maturation, interrupted the estrous cycle, induced oviductal and uterine hypotrophy. Estrous cyclicity was reestablished 60 days after AAS treatment. However, TC-treated mice still exhibited impaired reproductive capacity, a disturbance potentially related to deficiency in folliculogenesis, sex hormones production, and endometrial receptivity mediate by ER-α, PR, HOXA-10 and LIF down-regulation. Taken together, our findings indicated that in addition to female behavior, reproductive organs microstructure and function are markedly impaired by TC in a dose-dependent manner, whose time-dependent reversibility remains to be clarified.

A sex-specific dose-response curve for testosterone: could excessive testosterone limit sexual interaction in women? Menopause 2018; 24:462-470.

Abstract
Testosterone treatment increases sexual desire and well-being in women with hypoactive sexual desire disorder; however, many studies have shown only modest benefits limited to moderate doses. Unlike men, available data indicate women show a bell-shaped dose-response curve for testosterone, wherein a threshold dosage of testosterone leads to desirable sexual function effects, but exceeding this threshold results in a lack of further positive sexual effects or may have a negative impact. Emotional and physical side-effects of excess testosterone, including aggression and virilization, may counteract the modest benefits on sexual interaction, providing a possible explanation for a threshold dose of testosterone in women. In this commentary, we will review and critically analyze data supporting a curvilinear dose-response relationship between testosterone treatment and sexual activity in women with low libido, and also explore possible explanations for this observed relationship. Understanding optimal dosing of testosterone unique to women may bring us one step closer to overcoming regulatory barriers in treating female sexual dysfunction.

Mad men, women and steroid cocktails: a review of the impact of sex and other factors on anabolic androgenic steroids effects on affective behaviors. Psychopharmacology (Berl) 2016; 233:549-69. [PMID: 26758282 PMCID: PMC4751878 DOI: 10.1007/s00213-015-4193-6] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2015] [Accepted: 12/11/2015] [Indexed: 12/26/2022]
Abstract
RATIONALE For several decades, elite athletes and a growing number of recreational consumers have used anabolic androgenic steroids (AAS) as performance enhancing drugs. Despite mounting evidence that illicit use of these synthetic steroids has detrimental effects on affective states, information available on sex-specific actions of these drugs is lacking. OBJECTIVES The focus of this review is to assess information to date on the importance of sex and its interaction with other environmental factors on affective behaviors, with an emphasis on data derived from non-human studies. METHODS The PubMed database was searched for relevant studies in both sexes. RESULTS Studies examining AAS use in females are limited, reflecting the lower prevalence of use in this sex. Data, however, indicate significant sex-specific differences in AAS effects on anxiety-like and aggressive behaviors, interactions with other drugs of abuse, and the interplay of AAS with other environmental factors such as diet and exercise. CONCLUSIONS Current methods for assessing AAS use have limitations that suggest biases of both under- and over-reporting, which may be amplified for females who are poorly represented in self-report studies of human subjects and are rarely used in animal studies. Data from animal literature suggest that there are significant sex-specific differences in the impact of AAS on aggression, anxiety, and concomitant use of other abused substances. These results have relevance for human females who take these drugs as performance-enhancing substances and for transgender XX individuals who may illicitly self-administer AAS as they transition to a male gender identity.

Abstract
INTRODUCTION In spite of significant changes in the management policies of intersexuality, clinical evidence show that not all pubertal or adult individuals live according to the assigned sex during infancy. AIM The purpose of this study was to analyze the clinical management of an individual diagnosed as a female pseudohermaphrodite with congenital adrenal hyperplasia (CAH) simple virilizing form four decades ago but who currently lives as a monogamous heterosexual male. METHODS We studied the clinical files spanning from 1965 to 1991 of an intersex individual. In addition, we conducted a magnetic resonance imaging (MRI) study of the abdominoplevic cavity and a series of interviews using the oral history method. MAIN OUTCOME MEASURES Our analysis is based on the clinical evidence that led to the CAH diagnosis in the 1960s in light of recent clinical testing to confirm such diagnosis. RESULTS Analysis of reported values for 17-ketosteroids, 17-hydroxycorticosteroids, from 24-hour urine samples during an 8-year period showed poor adrenal suppression in spite of adherence to treatment. A recent MRI study confirmed the presence of hyperplastic adrenal glands as well as the presence of a prepubertal uterus. Semistructured interviews with the individual confirmed a life history consistent with a male gender identity. CONCLUSIONS Although the American Academy of Pediatrics recommends that XX intersex individuals with CAH should be assigned to the female sex, this practice harms some individuals as they may self-identify as males. In the absence of comorbid psychiatric factors, the discrepancy between infant sex assignment and gender identity later in life underlines the need for a reexamination of current standards of care for individuals diagnosed with CAH.
