Introduction The availability of modern methods of contraception has been described as the “first reproductive revolution” in the history of humanity. Indeed, the availability and widespread use of modern contraceptive modalities represents more than a technical advance: it constitutes a true “social revolution” that greatly contributed to changing the future of the human race [1]. […]

Introduction Current contraceptive methods, namely those based on hormonal contraception, really came to prominence in the 1960s, after Gregory Pincus and his colleagues published the first clinical trials in women on norethisterone and norethindrone, used to inhibit ovulation [1]. Contraceptive methods are commonly categorized as natural, barrier methods, short-acting hormonal forms of contraception, long-acting reversible […]

Introduction Caesarean section (CS) delivery rates have risen dramatically worldwide over the last three decades [1]. In Canada, there has been a 50.8% increase between 1997 and 2016.  In 2019, 288.80 per 1,000 live births (28.8%) were performed via caesarean delivery [1]. As surgical procedure rates increase and CS become one of the most common […]

Introduction Skin senescent changes are caused by reduced collagen, elasticity and decreased total body water content. The magnitude of these changes is directly proportional to increasing age. However, there is an increasing body of evidence that suggest that skin aging changes are directly correlated to menopausal age rather than chronological age, implying estrogen deficiency as […]

Introduction Endocrine-related cancer represents a broad area of major interest when considering the undesirable effect of hormones. This field of cancer with a hormonal background is often associated with common cancers such as breast and endometrial cancers, but also with less frequent neoplasms such as ovarian cancer. Colon cancer, or colorectal cancer to be more […]

Introduction In all eukaryote cells, mitochondria are the organelles providing most of the energy used by these cells and are therefore also called the “powerhouse of the cells”. In terms of evolutionary biology, these organelles originate either from endosymbiotically living aerobic bacteria or from incorporated factual anaerobic bacteria in archaea [1]. Structurally, mitochondria have two […]

Introduction The demand for up-to-date information in the palm of our hand and the exponential advancement of technology within the last decade has caused the modern world to become dependent on cellular telephones, specifically smart phones. As of 2020, 97% of Americans owned a cellular telephone and 85% of Americans owned a smartphone [1]. Nearly […]

Introduction Endometriosis is a prevalent condition which occurs in an estimated 1 out of 10 women during their reproductive lifespan [1]. Worldwide, this translates to 190 million women with endometriosis. The most commonly occurring symptom is dysmenorrhea, but clinical presentation and disease severity vary widely [1].  Endometriosis usually involves the pelvic organs including the peritoneum, […]

Introduction In 1942, Fuller Albright et al. described a disorder characterized by end-organ resistance to parathyroid hormone (PTH) resulting in increased serum PTH levels, hypocalcemia and hyperphosphatemia. The condition was named ‘pseudohypoparathyroidism’ (PHP) given that the PTH was elevated in the face of low calcium and high phosphorus levels [1]. These patients had specific somatic […]

Introduction Hysteroscopy, a frequently used tool in the diagnosis of infertility [1,2], is safe and easy to perform. Nonetheless, it is an invasive procedure, even when performed in an outpatient setting [1,2]. Thus, one should get the maximum informative output [3]. In the last decade, several methods for the evaluation of Fallopian tube patency using […]

Introduction During the last decades, a growing body of evidence has pointed to the need of focusing on cardio-metabolic health with a sex and gender-oriented approach, in order to reduce the burden of cardiovascular diseases (CVD), which are the leading cause of mortality in both men and women worldwide [1]. The misconception that CVD affect […]

Case report A 39-year-old transmale person was referred by his mental health practitioner (MHP) for gender-affirmative hormonal treatment (GAHT) after the diagnosis of gender incongruence was made according the DSM-V criteria. On admission a healthy sportive and clinically unnoticeable person with a female phenotype was seen. Body mass index (BMI) was 27 kg/m2 and smoking […]

Introduction When discussing about the metabolic syndrome (MS), many specialists agree that it is has numerous causes; the most important of which is insulin resistance [1]. MS is defined according to specific criteria that are summarized in Table 1. As it can be easily argued, central obesity is the main common criteria among the presented […]

1. Introduction 1.1 Male contraceptive methods: an unmet need Currently, nearly half of all pregnancies globally are unintended, totaling 121 million each year. In the United States, about 45% of pregnancies are unintended. Specifically, 27% of all pregnancies were “unscheduled” and 18% of pregnancies were “unwanted” according to a Guttmacher institute survey [1]. A large […]

1. Premature ovarian insufficiency: diagnosis, characteristics, and clinical features Premature ovarian insufficiency (POI) presents a complex challenge for both clinicians and patients. This condition is characterized by the absence of menstruation before the age of 40 [1]. The ovarian function gradually decreases, leading to its eventual cessation, which manifests in both morphological changes in the […]
