#1
Satish Kumar Gupta, Vidisha Minhas
To minimize human-animal conflicts for habitation and burden of zoonotic diseases, it is imperative to develop new strategies for wildlife population management. In this direction, contraceptive vaccines eliciting immune response against hormones/proteins critical for reproduction have emerged as one of the promising options. Contraceptive vaccines based on neutralization of gonadotropin releasing hormone (GnRH) have been used for inhibition of fertility in various species such as wild horses, white-tailed deer, pigs, cats, dogs etc...

OBJECTIVE: To explore factors associated with the diagnosis of provoked vestibulodynia (PVD) through (1) self-reported pain characteristics and (2) Friedrich's criteria (vestibular pain during sexual activity/gynaecological examination). We also identified cases in which incorrect diagnoses were assigned and explored group differences in gynaecological examination presentation and associations with self-reported pain. METHODS: Data were extracted from nine studies conducted in our research laboratory...

BACKGROUND: In the past, elevated estradiol levels were reported to downregulate the iron regulatory hormone hepcidin, thereby potentially improving iron metabolism. As estrogen plays a role in regulating the menstrual cycle and can influence the cytokine interleukin-6 (IL-6; a hepcidin up-regulator), this investigation examined the effects of estradiol supplementation achieved by the use of a monophasic oral contraceptive pill (OCP) on IL-6, hepcidin levels and iron status during the hormone-deplete versus hormone-replete phases within an oral contraceptive cycle (OCC)...

OBJECTIVES: To investigate the effects of a combined oral contraceptive (COC) containing 17β-estradiol (E2) 1.5 mg and nomegestrol acetate 2.5 mg (NOMAC/E2) on the sexual health of women affected by low sexual desire due to COCs containing ethinylestradiol. MATERIALS AND METHODS: Eighty-three women (age range 19-32) participated in the study. Sex hormone-binding globulin (SHBG), total testosterone (TT), and free androgen index (FAI) were measured. The Female Sexual Function Index (FSFI) and the Female Sexual Distress Scale (FSDS) questionnaires were used to assess sexual function and distress, respectively...

OBJECTIVES: Oral hormonal contraception is an effective contraceptive method as long as regular daily intake is maintained. However, a daily routine is a constraint for many women and can lead to missed pills, pill discontinuation and/or unintended pregnancy. This article describes the frequency of inconsistent use, the consequences, the risk factors and the possible solutions. METHODS: The article comprises a narrative review of the literature. RESULTS: Forgetting one to three pills per cycle is a frequent problem among 15-51% of users, generally adolescents...

Acne is a common, worldwide problem that is usually multifactorial in etiology, but androgens may play a pivotal role in the development and severity of acne. Endocrinopathies, such as polycystic ovarian syndrome, ovarian tumors, or adrenal hyperplasia or tumors, may be detected in some patients with acne, especially if acne is sudden in onset, associated with hirsutism or menstrual irregularities, or associated with cushingoid facies, acanthosis nigricans, patterned hair loss, or deepened voice. In these instances, serum-free and total testosterone, dehydroepiandrosterone, luteinizing hormone, and follicle stimulating hormone should be tested...

OBJECTIVES: The advantages of intrauterine contraception (IUC) are well established (highly effective, low discontinuation rate, easy to use, low cost, and suitable for immediate postpartum use), but low levels of use in many countries and declining use in others are causes for concern. Due to the ongoing Zika virus outbreak, public health officials are calling for the continued practice of safe sex and the delay of pregnancy. Our study was conducted to assess the current situation of IUC availability and provision in Latin America and to determine the role of national policies in meeting the contraceptive needs of the populations in these countries...

BACKGROUND: Only 10% of plasma TFPIα (TFPI) exists in the full length form, the rest circulates as a C-terminally truncated form. However, blood platelets exclusively contain full length TFPI, which is released at the site of injury upon platelet activation, and which could play an important local regulatory role in thrombin generation and prevention of thrombosis. METHODS: The anticoagulant activities of full length and truncated TFPI were investigated using thrombin generation assays...

Migraine is a disabling headache disorder, which affects up to 17% of the female population. Oestrogen withdrawal during the menstrual cycle or the hormone-free interval in users of combined hormonal contraceptives (CHC) plays a pivotal role. Two diary-based studies demonstrated a positive impact of the progestin-only pill (POP) desogestrel 75 μg on the frequency of the migraine attacks and pain intensity. In both studies, CHC users as well as nonusers were included, which makes it difficult to distinguish between the effect of taking women off the CHC and the benefit of the POP itself...

OBJECTIVE: A review of treatment options for menstrual migraine. BACKGROUND: Migraine affects ∼30 million people in the US. A subset of female migraineurs have migraines that are mainly associated with menstruation. Menstrual migraine (MM) is divided into pure MM and menstrually related migraine. Pure MM attacks occur only with menstruation and have a prevalence of 1%. Menstrually related migraine has a prevalence of 6-7%, and occurs both during menstruation as well as during the rest of the cycle...

Hereditary angioedema with normal C1 esterase inhibitor and mutations in the F12 gene (HAE-FXII) is associated with skin swellings, abdominal pain attacks, and the risk of asphyxiation due to upper airway obstruction. It occurs nearly exclusively in women. We report our experience treating HAE-FXII with discontinuation of potential trigger factors and drug therapies. The study included 72 patients with HAE-FXII. Potential triggers included estrogen-containing oral contraceptives (eOC), hormonal replacement therapy, or angiotensin-converting enzyme inhibitors...

Linda Rhodes
Over the last 40 years, researchers have explored methods to non-surgically suppress fertility in animals. Immunocontraception has been used to control wildlife populations but does not confer long-term immunity. The gonadotropin-releasing hormone (GnRH) agonist deslorelin, formulated as an implant to provide 6-month to 1-year suppression of fertility in male dogs, is available commercially in some countries. Neither of these approaches provide permanent sterility. A single-dose, permanent treatment would be a valuable tool in dog and cat population control...

Sterilization is a key strategy to reduce the number of domestic cats entering and killed in shelters each year. However, surgical sterilization is expensive and labour-intensive and cannot fully address the 70 million free-roaming cats estimated to exist in the United States. GonaCon™ is a gonadotropin-releasing hormone vaccine originally developed for use as a wildlife immunocontraceptive. An earlier formulation was tested in domestic cats and found to be safe and effective for long-term contraception. However, the current Environmental Protection Agency (EPA)-registered formulation consists of a different antigen-carrier protein and increased antigen concentration and has never been tested in cats...

BACKGROUND: In previous work in young women aged 15-30 years we measured breast water and fat using MR and obtained blood for hormone assays on the same day in the follicular phase of the menstrual cycle. Only serum growth hormone levels and sex hormone binding globulin (SHBG) were significantly associated with percent breast water after adjustment for covariates. The sex hormones estradiol, progesterone and testosterone were not associated with percent water in the breast in the follicular phase of the menstrual cycle...

CONTEXT: Understanding how women's preferences for certain attributes of contraceptive methods relate to their method choice can inform the content of contraceptive counseling. METHODS: Data from 715 women aged 18-29 who had ever used contraceptives were drawn from the 2009 National Survey of Reproductive and Contraceptive Knowledge. Chi-square tests and multivariable logistic regression analyses were used to examine how women's preferences for specific contraceptive attributes were related to their social and demographic characteristics and their current contraceptive choice...

BACKGROUND: Menstrually-related headache and headaches associated with oestrogen withdrawal are common conditions, whose pathophysiology has not been completely elucidated. In this study we evaluated the influence of combined hormonal contraceptives (CHC) on pain threshold in women presenting migraine attacks during hormone-free interval. FINDINGS: Eleven women with migraine attacks recurring exclusively during the oestrogen-withdrawal period were studied with the nociceptive flexion reflex, a neurophysiological assessment of the pain control systems, during the third week of active treatment and during the hormone-free interval...

Contraception is an essential tool in reproductive management of captive species. The Association of Zoos and Aquariums (AZA) Reproductive Management Center (RMC) gathers data on contraception use and provides recommendations. Although apes have been given oral contraceptive pills (OCPs) for at least 30 years, there have been no published reports with basic information on why the pill is administered, formulations and brands used, and effects on physiology and behavior. Here, we report survey results characterizing OCP use in bonobos (Pan paniscus) housed in North American zoos, as well as information accumulated in the RMC's Contraception Database...

REVIEW
J D Bergiannaki, P Kostaras
The gender based or gender sensitive pharmacology is a new research area. Differences among sexes are observed in several parameters of their pharmacokinetic which may relate to alteration of their pharmacodynamic as well. Most psychotropics are given per os, and the greater part of their absorption takes place in the small intestine. Premenopausal women have slower gastric emptying times and lower gastrointestinal blood flow which probably reduces the extent of drug absorption. The distribution of drugs is influenced by the relative lower body mass index, the lower blood volume and flow and the greater percentage of body fat of women...

BACKGROUND: Maladaptive emotional control is a defining feature of personality disorders. Yet little is known about the underlying physiological dynamics of emotional reactivity to psychosocial stress across distinct personality disorders. The current study compared subjective emotional responses with autonomic nervous system and HPA axis physiological responses to psychosocial stress in women with cluster C personality disorder (CPD) and borderline personality disorder (BPD). METHODS: Subjective mood ratings, salivary cortisol, heart rate (HR), and skin conductance level (SCL) were assessed before, during, and after exposure to a standardized psychosocial stress paradigm (Trier Social Stress Test, TSST) in 26 women with BPD, 20 women with CPD, and 35 healthy female controls...
