Role of gonadotropin-releasing hormone II in the mammalian nervous system.

Expert Rev Endocrinol Metab 2006 Jan;1(1):133-145

b Department of Biochemistry and Molecular Genetics, University of Virginia, School of Medicine, PO Box 800733, 1300 Jefferson Park Avenue, Charlottesville, VA 22908, USA.

Gonadotropin-releasing hormone (GnRH) is a small neuropeptide of which there are multiple structural variants. The first variant identified in mammals, GnRH I, controls the release of pituitary gonadotropins. More recently, a second isoform, GnRH II, first isolated in the bird, was identified in the mammalian brain and periphery. Read More

Multiple Evolutionary Routes to Monogamy: Modeling the Coevolution of Mating Decisions and Parental Investment.

Am Nat 2019 Feb 19;193(2):E29-E40. Epub 2018 Nov 19.

The relationships between mating decisions and parental investment are central to evolution, but to date few theoretical treatments of their coevolution have been developed. Here we adopt a demographically explicit, adaptive dynamics approach to analyze the coevolution of female mating decisions and parental investment of both sexes in a self-consistent way. Our models predict that where females cannot interfere with one another's mating decisions and where they do not differ in their survival and fecundity prospects, monogamy should be rare, favored only under harsh environmental conditions, in sparse populations.

Synthetic progestin etonogestrel negatively affects mating behavior and reproduction in Endler's guppies (Poecilia wingei).

Sci Total Environ 2019 Jan 24;663:206-215. Epub 2019 Jan 24.

Faculty of Fisheries and Protection of Waters, South Bohemian Research Centre of Aquaculture and Biodiversity of Hydrocenoses, University of South Bohemia in České Budějovice, Zátiší 728/II, 389 25, Vodňany, Czech Republic.

High rates of progestins consumption in the form of active ingredients in women's oral contraceptives and other hormonal preparations may lead to their increased concentrations in aquatic environments and subsequent harmful effect on fish reproduction. The objective of the present study was to assess the effect of etonogestrel, a third-generation synthetic progestin, on the reproductive behavior, fertility, gonads histology, and secondary sexual characteristics of male and female Endler's guppies (Poecilia wingei). Fish were subjected for 34 days to two concentrations of etonogestrel, including one possibly environmentally relevant (3. Read More

Attitudes and practices related to intrauterine devices for nulliparous women among Chinese health care providers.

Reprod Health 2019 Jan 31;16(1):10. Epub 2019 Jan 31.

NHC Key Lab. of Reproduction Regulation (Shanghai Institute of Planned Parenthood Research), Fudan University, Shanghai, 200237, China.

Background: Unintended pregnancy and induced abortion among young (unmarried or nulliparous) women have become serious social and health issues in China, which are thought to partly result from low use of long-acting reversible contraception, such as intrauterine devices (IUDs). Considering that providers may play an especially important role in increasing use of this particular method, we investigated Chinese health care providers' attitudes and practices regarding IUDs use for nulliparous women, and further examine the potential factors and reasons contributing to their attitudes and practices.

Methods: We recruited health care providers at two Chinese national academic conferences and surveyed them about knowledge of IUDs, willingness to recommend IUDs to nulliparous women, and their related practices. Read More

Life History in a Postconflict Society : Violent Intergroup Conflict Facilitates Fast Life-History Strategy.

Hum Nat 2019 Jan 24. Epub 2019 Jan 24.

Institute of Criminological and Sociological Research, Gračanička 18, Belgrade, 11000, Serbia.

Previous theoretical accounts have predicted that warfare and intergroup conflict are environmental factors that contribute to the emergence of a fast life-history strategy. However, this assumption has never been directly empirically tested. We examined youth who grew up in a territory that experienced violent intergroup conflict and compared them with a control group (N = 215) on various life-history measures: age of first sexual intercourse, mating behavior, desired timing of marriage and first reproduction and desired number of children.

Unbalanced biparental care during colony foundation in two subterranean termites.

Ecol Evol 2019 Jan 30;9(1):192-200. Epub 2018 Dec 30.

Institut de Recherche sur la Biologie de l'Insecte (UMR7261) CNRS - University of Tours Tours France.

Parental care is a major component of reproduction in social organisms, particularly during the foundation steps. Because investment into parental care is often costly, each parent is predicted to maximize its fitness by providing less care than its partner. However, this sexual conflict is expected to be low in species with lifelong monogamy, because the fitness of each parent is typically tied to the other's input. Read More

Effects of combined exposure of adult male mice to di-(2-ethylexyl)phthalate and nonylphenol on behavioral and neuroendocrine responses.

Chemosphere 2019 Jan 14;221:573-582. Epub 2019 Jan 14.

Sorbonne Université, CNRS, INSERM, Neuroscience Paris Seine, Institut de Biologie Paris-Seine, 75005 Paris, France. Electronic address:

The present study evaluates the effects of adult exposure to low doses of a mixture of di-(2-ethylexyl)phthalate (DEHP) and nonylphenol (NP) on reproductive neuroendocrine function and behavior. The neural circuitry that processes male sexual behavior is tightly regulated by testosterone and its neural metabolite estradiol. In previous studies, we showed that adult exposure of mice to low doses of each of these widespread environmental contaminants resulted in altered sexual behavior, without any effect on the regulation of the gonadotropic axis.

Exploring the Mechanism of Viral Peptide-Induced Membrane Fusion.

Adv Exp Med Biol 2018 ;1112:69-78

School of Chemistry, Sambalpur University, Burla, Odisha, India.

Membrane fusion is essential in several cellular processes in the existence of eukaryotic cells such as cellular trafficking, compartmentalization, intercellular communication, sexual reproduction, cell division, and endo- and exocytosis. Membrane fusion proceeds in model membranes as well as biological membranes through the rearrangement of lipids. The stalk hypothesis provides a picture of the general nature of lipid rearrangement based on mechanical properties and phase behavior of water-lipid mesomorphic systems. Read More

Toward Gender-inclusive, Nonjudgmental Alcohol Interventions for Pregnant People: Challenging Assumptions in Research and Treatment.

J Addict Med 2018 Dec 27. Epub 2018 Dec 27.

Institute for Gender, Race, Sexuality and Social Justice, University of British Columbia, British Columbia, Canada (AJL); School of Population and Public Health, University of British Columbia, British Columbia, Canada (AJL); British Columbia Centre on Substance Use, Vancouver, Canada (RK); Department of Medicine, University of British Columbia, Vancouver, Canada (RK).

: Epidemiological and clinical evidence clearly indicates that binge and/or heavy alcohol use while pregnant can be dangerous for the fetus. As such, there is a large body of research evaluating interventions to address harms associated with alcohol use during pregnancy. Unfortunately, based on our assessment of the scientific literature in this area, including a reading of three high-impact systematic reviews, there are several key areas where the language being used is hindering efforts to address alcohol harms during pregnancy in nonjudgmental and gender-inclusive ways.

University of Cambridge, Cambridge, UK.

Heterosexual reproduction is often seen as and , with the two descriptors commonly understood as mutually reinforcing. I argue that, despite their apparent similarity, the meanings of "normal" and "natural" are distinct in important ways-a distinction that questions the positioning of lesbian motherhood and gay fatherhood as inferior. Through an analysis of lesbian, gay, and bisexual people's ethical judgments about different ways of creating families, I show that pathways to parenthood that make a family appear "more normal" rely on means of reproduction that seem, in fact, "less natural.

Heather Jacobson

Reprod Biomed Soc Online 2018 Nov 18;7:14-23. Epub 2018 Nov 18.

Department of Sociology and Anthropology, The University of Texas at Arlington, Arlington, TX, USA.

Gestational surrogacy via egg donation is an expensive - and sometimes ambivalently undertaken - but increasingly popular route to planned fatherhood for some gay men. The surrogacy market in the USA plays an important role for gay men with the financial resources to access these services, as it is currently the only stable, commercial market in which there are legal protections for openly gay men. While a small, ethnographic and qualitative literature on the experiences of gay fathers via surrogacy exists, less is known about the state of the surrogacy industry towards gay men as clients.

Sex-Related Differences in Lactotroph Tumor Aggressiveness Are Associated With a Specific Gene-Expression Signature and Genome Instability.

Front Endocrinol (Lausanne) 2018 30;9:706. Epub 2018 Nov 30.

Centre de Recherche en Cancérologie de Lyon (CRCL), INSERM U1052, CNRS UMR5286, Université de Lyon, Lyon, France.

Sex-related differences have been reported in various cancers, in particular men with lactotroph tumors have a worse prognosis than women. While the underlying mechanism of this sexual dimorphism remains unclear, it has been suggested that a lower estrogen receptor alpha expression may drive the sex differences observed in aggressive and malignant lactotroph tumors that are resistant to dopamine agonists. Based on this observation, we aimed to explore the molecular importance of the estrogen pathway through a detailed analysis of the transcriptomic profile of lactotroph tumors from 20 men and 10 women.

Department of Biology, Duke University, Box 90338, Durham, North Carolina, 27708, USA.

Premise Of The Study: Ecological differentiation (ED) between sexual and asexual organisms may permit the maintenance of reproductive polymorphism. Several studies of sexual/asexual ED in plants have shown that the geographic ranges of asexuals extend beyond those of sexuals, often in areas of higher latitude or elevation. But very little is known about ED at fine scales, wherein coexistence of sexuals and asexuals may be permitted by differential niche occupation. Read More

Male-inflicted wounds have opposite effects on hair cortisol for captive male and female rhesus macaques (Macaca mulatta) following new group formation.

Primates 2019 Jan 30;60(1):51-62. Epub 2018 Nov 30.

Department of Anthropology, University of California, Davis, Davis, CA, USA.

Sexual dimorphism in body size, aggression, and dispersal patterns may affect the degree to which males and females perceive aggression from either sex as stressful. Whereas male macaques typically disperse to new groups at maturity, thus encountering many unfamiliar individuals of both sexes, females are philopatric, usually only encountering unfamiliar males who transfer into their natal groups. In rare circumstances, however, group fusions can expose both males and females to many novel individuals, which often increases aggression. Read More

A mating plug in a squid? Sneaker spermatophores can block the female sperm-storage organ in Doryteuthis plei.

Zoology (Jena) 2018 10 8;130:47-56. Epub 2018 Sep 8.

Department of Zoology, Institute of Biosciences, University of São Paulo, Rua do Matão, Travessa 14, n. 101, 05508-090, São Paulo, SP, Brazil. Electronic address:

Males from numerous animal taxa have evolved strategies for obstructing the female genitalia with copulatory plugs, reducing the risk of sperm competition and thus resulting in an advantage in sexual selection. Several lines of evidence suggest that sperm competition is a common feature in the complex squid mating systems, which include the evolution of alternative mating tactics (consort vs. sneaker).

Effects of Oxytocin on Fear Memory and Neuroinflammation in a Rodent Model of Posttraumatic Stress Disorder.

Int J Mol Sci 2018 Dec 3;19(12). Epub 2018 Dec 3.

Graduate Institute of Medical Sciences, National Defense Medical Center, Taipei 11490, Taiwan.

Posttraumatic stress disorder (PTSD) is a trauma-induced mental disorder characterized by fear extinction abnormalities, which involve biological dysfunctions among fear circuit areas in the brain. Oxytocin (OXT) is a neuropeptide that regulates sexual reproduction and social interaction and has recently earned specific attention due to its role in adjusting neurobiological and behavioral correlates of PTSD; however, the mechanism by which this is achieved remains unclear. The present study aimed to examine whether the effects of OXT on traumatic stress-induced abnormalities of fear extinction (specifically induced by single prolonged stress (SPS), an animal model of PTSD) are associated with pro-inflammatory cytokines.

Contraception and abortion knowledge, attitudes and practices among adolescents from low and middle-income countries: a systematic review.

BMC Health Serv Res 2018 Nov 29;18(1):909. Epub 2018 Nov 29.

Department of Epidemiology & Biostatistics, School of Public Health, University of Zambia, Lusaka, Zambia.

Background: Adolescents face significant barriers to contraception access and utilization that result in adverse health effects of early pregnancy and childbirth. Unsafe abortions continue to occur partly due to failure to prevent pregnancies, with Sub-Saharan Africa contributing the most significant burden of all unsafe abortions among young people globally, of which a quarter occurs in those aged 15-19 years. We aimed to conduct a systematic review of the contraceptive and abortion knowledge, attitudes and practices of adolescents in low and middle-income countries to increase the understanding of the sexual and reproductive health dynamics that they face.

Ecol Evol 2018 Nov 16;8(21):10594-10607. Epub 2018 Oct 16.

Department of Anthropology University of California Davis California.

Adults sometimes disperse, while philopatric offspring inherit the natal site, a pattern known as . Despite a decades-old empirical literature, little theoretical work has explored when natural selection may favor bequeathal. We present a simple mathematical model of the evolution of bequeathal in a stable environment, under both global and local dispersal. Read More

It is universally accepted that lifestyle interventions are the first step towards a good overall, reproductive and sexual health. Cessation of unhealthy habits, such as tobacco, alcohol and drug use, poor nutrition and sedentary behavior, is suggested in order to preserve/improve fertility in humans. However, the possible risks of physical exercise per se or sports on male fertility are less known. Read More

Intentions on contraception use and its associated factors among postpartum women in Aksum town, Tigray region, northern Ethiopia: a community-based cross- sectional study.

Reprod Health 2018 Nov 9;15(1):188. Epub 2018 Nov 9.

Department of Epidemiology and Biostatistics, School of Public Health, College of Health Sciences, Aksum University, Aksum, Tigray, Ethiopia.

Background: Increased access to contraceptive methods has been established as a cost-effective strategy for developing countries to reduce maternal and child mortality. Intentions to contraceptive uptake appear to be best predictors of actual contraceptive practice than the unmet need. However, intention to contraceptive use in Ethiopia particularly among postpartum women is not well assessed. Read More

Parthenogenetic female populations in the brown alga Scytosiphon lomentaria (Scytosiphonaceae, Ectocarpales): decay of a sexual trait and acquisition of asexual traits.

J Phycol 2018 Nov 9. Epub 2018 Nov 9.

Department of Biological Sciences, Faculty of Science, Hokkaido University, Sapporo, 060-0810, Japan.

In isogamous brown algae, the sexuality of populations needs to be tested by laboratory crossing experiments, as the sexes of gametophytes are morphologically indistinguishable. In some cases, gamete fusion is not observed and the precise reproductive mode of the populations is unknown. In the isogamous brown alga Scytosiphon lomentaria in Japan, both asexual (gamete fusion is unobservable) and sexual populations (gamete fusion is observable) have been reported. Read More
