There is conflicting evidence regarding whether females are more adversely affected after concussion than males. Further, recent research suggests that hormonal contraceptive (HC) use may affect symptom severity and duration post-concussion. The objective of this study was to examine the effects of sex and HC use on outcomes following concussion among collegiate varsity athletes. We hypothesized that females would have longer length of recovery (LOR), and that peak symptom severity would be associated with longer LOR in both males and females. Among females, we hypothesized that non-HC users would have longer LOR and higher peak symptom severity than HC users. Ninety collegiate student-athletes were included in this study (40 males, 50 females; 24 HC users, 25 non-HC users). Demographic, injury, and recovery information was abstracted via retrospective record review. LOR was defined as days between injury and clearance for full return to play by team physician. Peak symptom severity score (Sport Concussion Assessment Tool [SCAT] 2 or 3) was used in analyses. Study results revealed that males had shorter LOR than females (F[1, 86] = 5.021, p < 0.05, d = 0.49), but had comparable symptom severity scores. Symptom severity was strongly related to LOR for males (r = 0.513, p < 0.01) but not females (r = -0.003, p > 0.05). Among females, non-HC users demonstrated higher symptom severity than HC users (F[1,47] = 5.142, p < 0.05, d = 0.70). No significant differences between female HC users and non-HC users on LOR were observed. This study provides evidence for differential concussion outcomes between male and female collegiate athletes and between HC users and nonusers among females.

Transgender individuals identify as a gender different than their sex designated at birth. Transgender athletes, as the name implies, are transgender individuals who participate in sports/athletics. By reviewing the literature relevant to transgender athletes and adding commentary on important considerations, this article acts as a primer for the sports medicine clinician on the care of transgender athletes. We cover terminology, epidemiology, policy, and relevant medical considerations. Literature relevant for medical care specific to transgender athletes is still relatively sparse. We highlight many recommended areas of future research with the potential to make valuable contributions to evidence-based sports medicine practice for this population.

The American Medical Society for Sports Medicine (AMSSM) convened a group of experts to develop a Position Statement addressing the problem of sexual violence in sport. The AMSSM Sexual Violence in Sport Task Force held a series of meetings over 7 months, beginning in July 2019. Following a literature review, the Task Force used an iterative process and expert consensus to finalise the Position Statement. The objective of this Position Statement is to raise awareness of this critical issue among sports medicine physicians and to declare a commitment to engage in collaborative, multidisciplinary solutions to reduce sexual violence in sport.

Ice hockey is a popular collision sport with a growing number of female athletes participating each year. As participation among girls and women continues to increase, it will be important to recognize common injuries occurring during women's games. Despite difference in the rules that prohibit body checking in women's and girls' games, injury profiles are similar to those of their male counterparts. Concussions, contusions, acromioclavicular joint injuries, ligamentous knee injuries, and muscle strains occur during women's ice hockey games, with groin strains accounting for the most common practice injury. This article will review both injury rates and common injuries occurring in women's ice hockey, with a focus on the observed concussion rate and groin injuries.

Synchronized skating is a unique sport of team skating and currently represents the largest competitive discipline in U.S. Figure Skating. Synchronized skating allows skaters to compete as part of a team with opportunities to represent their country in international competitions. As the popularity of the sport continues to grow, more of these athletes will present to sports medicine clinics with injuries and illnesses related to participation in synchronized skating. The purpose of this article is to review the common injuries and medical conditions affecting synchronized skaters.
