Reproductive System Reference Sheet 3: GLOSSARY Anus – The opening in the buttocks from which bowel movements come when a person goes to the bathroom. It is part of the digestive system; it gets rid of body wastes. Buttocks – The medical word for a person’s “bottom” or “rear end.” Cervix – The opening of the uterus into the vagina. Circumcision – An operation to remove the foreskin from the penis. Cowper’s Glands – Glands on either side of the urethra that make a discharge which lines the urethra when a man gets an erection, making it less acid-like to protect the sperm. Clitoris – The part of the female genitals that’s full of nerves and becomes erect. It has a glans and a shaft like the penis, but only its glans is on the out side of the body, and it’s much smaller. Discharge – Liquid. Urine and semen are kinds of discharge, but the word is usually used to describe either the normal wetness of the vagina or the abnormal wetness that may come from an infection in the penis or vagina. Duct – Tube, the fallopian tubes may be called oviducts, because they are the path for an ovum. -

Semen Arousal: Its Prevalence, Relationship to HIV Risk Practices
C S & lini ID ca A l f R o e l s Klein, J AIDS Clin Res 2016, 7:2 a e Journal of n a r r DOI: 10.4172/2155-6113.1000546 c u h o J ISSN: 2155-6113 AIDS & Clinical Research Research Article Open Access Semen Arousal: Its Prevalence, Relationship to HIV Risk Practices, and Predictors among Men Using the Internet to Find Male Partners for Unprotected Sex Hugh Klein* Kensington Research Institute, USA Abstract Purpose: This paper examines the extent to which men who use the Internet to find other men for unprotected sex are aroused by semen. It also looks at the relationship between semen arousal and involvement in HIV risk practices, and the factors associated with higher levels of semen arousal. Methods: 332 men who used any of 16 websites targeting unprotected sex completed 90-minute telephone interviews. Both quantitative and qualitative data were collected. A random sampling strategy was used. Semen arousal was assessed by four questions asking men how much they were turned on by the way that semen smelled, tasted, looked, and felt. Results: 65.1% of the men found at least one sensory aspect of semen to be “fairly” or “very” arousing, compared to 10.2% being “not very” or “not at all” aroused by all four sensory aspects of semen. Multivariate analysis revealed that semen arousal was related to greater involvement in HIV risk practices, even when the impact of other salient factors such as demographic characteristics, HIV serostatus, and psychological functioning was taken into account. Five factors were found to underlie greater levels of semen arousal: not being African American, self-identification as a sexual “bottom,” being better educated, being HIV-positive, and being more depressed. -
Commentary Unprotected: Condoms, Bareback Porn, and the First Amendment
Commentary Unprotected: Condoms, Bareback Porn, and the First Amendment Bailey J. Langnert ABSTRACT In November 2012, Los Angeles County voters passed Measure B, or the Safer Sex in the Adult Film Industry Act. Measure B mandated condom use by all porn performers in adult films produced within county borders and created a complex regulatory process for adult film producers that included permitting, mandatory public health trainings, and warrantless administrative searches. Shortly after its passage, Vivid Entertainment filed a lawsuit to enjoin the enforcement of Measure B, arguing that the Measure violated their First Amendment right to portray condomless sex in porn. In December 2014, the Ninth Circuit upheld the district court's decision upholding the constitutionality of Measure B. Notably, the mainstream discourse surrounding the Measure B campaign, as well as the legal arguments put forth in the lawsuit, focused exclusively on straight pornography while purporting to represent all porn. As a result, an entire genre of condomless pornography went unrepresented in the discussion: bareback porn, which portrays intentional unprotected anal sex between men. Excluding bareback porn from the lawsuit represented a missed opportunityfor Vivid in its challenge of Measure B. There are several political messages underlying bareback porn unique to that genre that might have resulted in the t The author received a law degree from the University of California, Berkeley, School of Law (Boalt Hall) in 2015.

Our clinical team includes 3 sub-specialty urologists, and an andrology lab director. We collaborate closely with the REI and oncologists. In addition to clinical evaluation and operative training, fellows will gain experience in clinical andrology lab tests, management of infertility in men with spinal cord injury and exposure to a fertility preservation program. Research Program: We have a very active research program with basic science projects on human testis models to evaluate genetics of male infertility and clinical trial to evaluate the effect of clomiphene citrate on idiopathic male infertility. We also have dedicated laboratory space to study animal models with Klinefelter syndrome and Leydig stem cells.

Abstract: Sperm quality assessment is the first step for evaluating male fertility and includes the estimation of sperm concentration, motility, and morphology. Nevertheless, other parameters can be assessed providing additional information on the male reproductive potential. This study aimed to evaluate and correlate the oxidative status, mitochondrial functionality, and motility in sperma- tozoa of two marine invertebrate (Ciona robusta and Mytilus galloprovincialis) and one mammalian (Bos taurus) species. By combining fluorescent staining and spectrofluorometer, sperm oxidative status was evaluated through intracellular reactive oxygen species (ROS) and plasma membrane lipid peroxidation (LPO) analysis. Mitochondrial functionality was assessed through the mitochondrial membrane potential (MMP). In the three examined species, a negative correlation emerged between sperm motility vs ROS levels and LPO. Sperm motility positively correlated with MMP in bovine, whereas these parameters were not related in ascidian or even negatively related in mussel sper- matozoa. MMP was negatively related to ROS and LPO levels in ascidians, only to LPO in bovine, Citation: Gallo, A.; Esposito, M.C.; and positively related in mussel spermatozoa. -
Gay Men and Barebacking: Radical Or Realistic?

Roberson Prepared for Dr. JoAnn Pavletich ENG 3305 Advanced Essay Writing Fall 2009 Semester Gay Men and Barebacking: Radical or Realistic? Page 1 of 17 By Eric J. Roberson Gay Men and “Barebacking”: Radical or Realistic? By Eric J. Roberson Sex is not a competitive sport, and if you are gay and think it is then you should listen up! “HIV is a serious long-term condition, and young gay men remain the group of young people most at risk” (“UK Same-Sex Relationships 1). Some gay men willfully and deliberately discard condoms in preference for unprotected sex. Regardless of your age, this essay will not convince you on what to do with your “hard on,” but it may help you decide to get tested and to put on a condom before your next casual sexual encounter. Consider these three simple solutions: communication before sex, compassion for others, and condoms for casual encounters. If you happen to be straight and are reading this essay, do not put it down. Straight people who have gay friends may learn about some of the challenges gay men face in leading fulfilling relationships. You may also gain ideas on how to be more supportive. Regardless of your sexual orientation, the goal is to expose how the internet has shaped the practice of barebacking and other mitigating factors that compel gay men to consciously and explicitly eschew condoms during anal intercourse – colloquially known as “barebacking” (Gastaldo, et.
