Couvade Syndrome
Couvade syndrome, also called sympathetic pregnancy, is a proposed condition in which an expectant father experiences some of the same symptoms and behavior as his pregnant partner. These most often include major weight gain, altered hormone levels, morning nausea, and disturbed sleep patterns. In more extreme cases, symptoms can include labor pains, fatigue, postpartum depression, and nosebleeds. The labor pain symptom is commonly known as ''sympathy pain''. The source of Couvade syndrome is a matter of debate. Some believe it to be a psychosomatic condition, while others believe it may have biological causes relating to hormone changes. The name derives from " couvade", a class of male pregnancy rituals. Symptoms Symptoms experienced by the partner can include stomach pain, back pain, indigestion, changes in appetite, weight gain, acne, diarrhea, constipation, headache, toothache, cravings, nausea, breast augmentation, breast growth, dry navel, hardening of the nipple, ...

Morning Sickness
Morning sickness, also called nausea and vomiting of pregnancy (NVP), is a symptom of pregnancy. Despite the name, nausea or vomiting can occur at any time during the day. Typically the symptoms occur between the 4th and 16th weeks of pregnancy. About 10% of women still have symptoms after the 20th week of pregnancy. A severe form of the condition is known as hyperemesis gravidarum and results in weight loss. The cause of morning sickness is unknown but may relate to changing levels of the hormone human chorionic gonadotropin. Some have proposed that morning sickness may be useful from an evolutionary point of view. Diagnosis should only occur after other possible causes have been ruled out. Abdominal pain, fever, or headaches are typically not present in morning sickness. Morning sickness affects about 70–80% of all pregnant women to some extent. About 60% of women experience vomiting. Hyperemesis gravidarum occurs in about 1.6% of pregnancies. Morning sickness can neg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genitourinary System
The genitourinary system, or urogenital system, are the sex organs of the reproductive system and the organs of the urinary system. These are grouped together because of their proximity to each other, their common embryological origin and the use of common pathways. Because of this, the systems are sometimes imaged together. In placental mammals (including humans), the male urethra goes through and opens into the penis while the female urethra and vagina empty through the vulva. The term "apparatus urogenitalis" was used in '' Nomina Anatomica'' (under splanchnologia) but is not used in the current ''Terminologia Anatomica''. Development The urinary and reproductive organs are developed from the intermediate mesoderm. The permanent organs of the adult are preceded by a set of structures that are purely embryonic and that, with the exception of the ducts, disappear almost entirely before the end of fetal life. These embryonic structures are on either side: the pronephros, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andrology
Andrology (from , ''anēr'', genitive , ''andros'' 'man' and , ''-logy, -logia'') is a name for the medicine, medical specialty that deals with male health, particularly relating to the problems of the male reproductive system and urology, urological problems that are unique to men. It is the parallel to gynecology, which deals with medical issues which are specific to female health, especially reproductive and urologic health. Process Andrology covers anomalies in the connective tissues pertaining to the genitalia, as well as changes in the volume of cells, such as in genital hypertrophy or macrogenitosomia. From reproductive and urologic viewpoints, male-specific medical and surgery, surgical procedures include vasectomy, vasovasostomy (one of the vasectomy reversal procedures), orchidopexy, circumcision, sperm/semen cryopreservation, surgical sperm retrieval, semen analysis (for fertility or post-vasectomy), sperm preparation for assisted reproductive technology (ART) as wel ...

Testosterone
Testosterone is the primary male sex hormone and androgen in Male, males. In humans, testosterone plays a key role in the development of Male reproductive system, male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of androgenic hair, body hair. It is associated with increased aggression, sex drive, Dominance hierarchy, dominance, courtship display, and a wide range of behavioral characteristics. In addition, testosterone in both sexes is involved in health and well-being, where it has a significant effect on overall mood, cognition, social and sexual behavior, metabolism and energy output, the cardiovascular system, and in the prevention of osteoporosis. Insufficient levels of testosterone in men may lead to abnormalities including frailty, accumulation of adipose fat tissue within the body, anxiety and depression, sexual performance issues, and bone loss.

Estradiol
Estradiol (E2), also called oestrogen, oestradiol, is an estrogen steroid hormone and the major female sex hormone. It is involved in the regulation of female reproductive cycles such as estrous and menstrual cycles. Estradiol is responsible for the development of female secondary sexual characteristics such as the breasts, widening of the hips and a female pattern of fat distribution. It is also important in the development and maintenance of female reproductive tissues such as the mammary glands, uterus and vagina during puberty, adulthood and pregnancy. It also has important effects in many other tissues including bone, fat, skin, liver, and the brain. Though estradiol levels in males are much lower than in females, estradiol has important roles in males as well. Apart from humans and other mammals, estradiol is also found in most vertebrates and crustaceans, insects, fish, and other animal species. Estradiol is produced within the follicles of the ovaries and in oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cortisol
Cortisol is a steroid hormone in the glucocorticoid class of hormones and a stress hormone. When used as medication, it is known as hydrocortisone. Cortisol is produced in many animals, mainly by the ''zona fasciculata'' of the adrenal cortex in an adrenal gland. In other tissues, it is produced in lower quantities. By a Circadian rhythm, diurnal cycle, cortisol is released and increases in response to Stress (biology), stress and a low Blood sugar, blood-glucose concentration. It functions to increase blood sugar through gluconeogenesis, suppress the immune system, and aid in the metabolism of calories. It also decreases bone formation. These stated functions are carried out by cortisol binding to glucocorticoid or mineralocorticoid receptors inside a cell, which then bind to DNA to affect gene expression. Health effects Metabolic response Metabolism of glucose Cortisol plays a crucial role in regulating glucose metabolism and promotes gluconeogenesis (glucose synthes ...

Prolactin
Prolactin (PRL), also known as lactotropin and mammotropin, is a protein best known for its role in enabling mammals to produce milk. It is influential in over 300 separate processes in various vertebrates, including humans. Prolactin is secreted from the pituitary gland in response to eating, mating, estrogen treatment, ovulation and nursing. It is secreted heavily in pulses in between these events. Prolactin plays an essential role in metabolism, regulation of the immune system and pancreatic development. Discovered in non-human animals around 1930 by Oscar Riddle and confirmed in humans in 1970 by Henry Friesen, prolactin is a peptide hormone, encoded by the ''PRL'' gene. In mammals, prolactin is associated with milk production; in fish it is thought to be related to the control of water and salt balance. Prolactin also acts in a cytokine-like manner and as an important regulator of the immune system. It has important cell cycle-related functions as a growth-, diffe ...

Oedipal Conflict
In classical psychoanalytic theory, the Oedipus complex is a son's sexual attitude towards his mother and concomitant hostility toward his father, first formed during the phallic stage of psychosexual development. A daughter's attitude of desire for her father and hostility toward her mother is referred to as the feminine (or female) Oedipus complex. The general concept was considered by Sigmund Freud in '' The Interpretation of Dreams'' (1899), although the term itself was introduced in his paper "A Special Type of Choice of Object Made by Men" (1910). Freud's ideas of castration anxiety and penis envy refer to the differences of the sexes in their experience of the Oedipus complex. The complex is thought to persist into adulthood as an unconscious psychic structure which can assist in social adaptation but also be the cause of neurosis. According to sexual difference, a ''positive'' Oedipus complex refers to the child's sexual desire for the opposite-sex parent and aversion to th ...

Parturition Envy
In psychology, womb envy denotes the envy that men may feel of the biological functions of women (pregnancy, childbirth, breastfeeding). The neo-Freudian psychiatrist Karen Horney (1885–1952) proposed this as a male psychological trait. These emotions could fuel the social subordination of women, and drive men to succeed in other areas of life, such as business, medicine, law, and politics. Each term is analogous to the concept of female penis envy presented in Freudian psychology. In this they address the gender role social dynamics underlying the "envy and fascination with the female breasts and lactation, with pregnancy and childbearing, and vagina envy hatare clues and signs of transsexualism and to a femininity complex of men, which is defended against by psychological and sociocultural means". Theory Womb envy denotes the envy men may feel towards a woman's role in nurturing and sustaining life. In coining the term, the Neo-Freudian psychiatrist Karen Horney (1885– ...

Sibling Rivalry
Sibling rivalry is a type of competition or animosity among siblings, whether blood-related or not. In childhood, siblings generally spend more time together than they do with parents. Sibling bonds are influenced by factors such as parental treatment, birth order, personality, people and experiences outside the family. Sibling rivalry is more prominent when children are close in age and of the same gender and/or where one or multiple children are intellectually gifted. Throughout the lifespan According to observational studies by Judith Dunn, children are sensitive to differences in parental treatment from one year of age. From 18 months, siblings can understand family rules and know how to comfort and be kind to each other. By the age of 3, children have a sophisticated grasp of social rules, can evaluate themselves in relation to their siblings, and know how to adapt to circumstances within the family. Sibling rivalry often continues throughout childhood and can be fru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insomnia
Insomnia, also known as sleeplessness, is a sleep disorder where people have difficulty sleeping. They may have difficulty falling asleep, or staying asleep for as long as desired. Insomnia is typically followed by daytime sleepiness, low energy, irritability, and a depression (mood), depressed mood. It may result in an increased risk of accidents of all kinds as well as problems focusing and learning. Insomnia can be short term, lasting for days or weeks, or long term, lasting more than a month. The concept of the word ''insomnia'' has two distinct possibilities: insomnia disorder (ID) or insomnia symptoms, and many abstracts of randomized controlled trials and systematic reviews often underreport on which of these two possibilities the word refers to. Insomnia can occur independently or as a result of another problem. Conditions that can result in insomnia include psychological stress, chronic pain, heart failure, hyperthyroidism, heartburn, restless leg syndrome, menopause ...

Sleep
Sleep is a state of reduced mental and physical activity in which consciousness is altered and certain Sensory nervous system, sensory activity is inhibited. During sleep, there is a marked decrease in muscle activity and interactions with the surrounding environment. While sleep differs from wakefulness in terms of the ability to react to Stimulus (physiology), stimuli, it still involves active Human brain, brain patterns, making it more reactive than a coma or disorders of consciousness. Sleep occurs in sleep cycle, repeating periods, during which the body alternates between two distinct modes: rapid eye movement sleep (REM) and Non-rapid eye movement sleep, non-REM sleep. Although REM stands for "rapid eye movement", this mode of sleep has many other aspects, including virtual Rapid eye movement sleep#Muscle, paralysis of the body. Dreams are a succession of images, ideas, emotions, and sensations that usually occur involuntarily in the mind during certain stages of sleep. ...
