Introduction: No controversy can be more controversial than that regarding the existence of the G-spot, an anatomical and physiological entity for women and many scientists, yet a gynecological UFO for others.
Methods: The pros and cons data have been carefully reviewed by six scientists with different opinions on the G-spot. This controversy roughly follows the Journal of Sexual Medicine Debate held during the International Society for the Study of Women's Sexual Health Congress in Florence in the February of 2009.
Main Outcome Measure: To give to The Journal of Sexual Medicine's reader enough data to form her/his own opinion on an important topic of female sexuality.
Results: Expert #1, who is JSM's Controversy section editor, reviewed histological data from the literature demonstrating the existence of discrete anatomical structures within the vaginal wall composing the G-spot. He also found that this region is not a constant, but can be highly variable from woman to woman. These data are supported by the findings discussed by Expert #2, dealing with the history of the G-spot and by the fascinating experimental evidences presented by Experts #4 and #5, showing the dynamic changes in the G-spot during digital and penile stimulation. Experts #3 and #6 argue critically against the G-spot discussing the contrasting findings so far produced on the topic.
Conclusion: Although a huge amount of data (not always of good quality) have been accumulated in the last 60 years, we still need more research on one of the most challenging aspects of female sexuality.

Factors Associated with Low/Moderate Perceived Risk for HIV Acquisition Among Gay, Bisexual, and Other Men Who Have Sex with Men Eligible to Use Pre-exposure Prophylaxis from Brazil, Mexico, and Peru.

Perceived risk for HIV acquisition among gay, bisexual, and other men who have sex with men (GBMSM) may not align with their actual sexual HIV exposure. Factors associated with low/moderate perceived risk among GBMSM eligible for pre-exposure prophylaxis (PrEP) (based on their high estimated HIV exposure) have been poorly described in Latin America. This is a secondary analysis of a 2018 web-based cross-sectional survey in Brazil, Mexico, and Peru.

Prior cross-sectional research established that four distinct responses to sexual rejection are associated with sexual and relationship well-being among couples affected by Sexual Interest/Arousal Disorder (SIAD). Examining these associations daily and prospectively will provide insight into within-person variations, temporality, and directionality. Women and gender-diverse individuals diagnosed with SIAD and their partners (N = 232 couples) completed a baseline survey, 56-day diary, and 6-month follow-up survey, assessing responses to sexual rejection, sexual satisfaction, dyadic sexual desire, sexual distress, and relationship satisfaction.

Department of Surgery, Section of Urology, Dartmouth Hitchcock Medical Center, Lebanon, NH 03756, United States.
Background: Understanding patient goals for metoidioplasty and phalloplasty gender-affirming surgery (MaPGAS) is paramount to achieving satisfactory, preference-sensitive outcomes, yet there is a lack of understanding of MaPGAS priorities and how these may vary between transgender men and non-binary individuals assigned female at birth (AFAB).
Aim: To understand the surgical goals of transgender men and non-binary individuals AFAB considering MaPGAS.
Methods: An online survey was created following literature review and qualitative interviews and distributed via social media and a community health center to participants AFAB aged ≥18 years who had considered but not yet undergone MaPGAS.
Meiosis and retinoic acid in the mouse fetal gonads: An unforeseen twist.

In mammals, differentiation of germ cells is crucial for sexual reproduction, involving complex signaling pathways and environmental cues defined by the somatic cells of the gonads. This review examines the long-standing model positing that all-trans retinoic acid (ATRA) acts as a meiosis-inducing substance (MIS) in the fetal ovary by inducing expression of STRA8 in female germ cells, while CYP26B1 serves as a meiosis-preventing substance (MPS) in the fetal testis by degrading ATRA and preventing STRA8 expression in the male germ cells until postnatal development. Recent genetic studies in the mouse challenge this paradigm, revealing that meiosis initiation in female germ cells can occur independently of ATRA signaling, with key roles played by other intrinsic factors like DAZL and DMRT1, and extrinsic signals such as BMPs and vitamin C.

The aim of this study was to describe the extent to which men in psychiatric care have experienced emotional, physical, and sexual abuse during the life course and the association between this experience and being a perpetrator oneself. The aim was also to identify who exposed them to abuse and whether there was an association between the category of abuser and being a perpetrator oneself. A cross-sectional study was performed using the self-administered NorVold Abuse Questionnaire for men.
