A vaginal delivery is the birth of offspring in mammals (babies in humans) through the vagina (also called the "birth canal"). [1] It is the most common method of childbirth worldwide. [ 2 ] It is considered the preferred method of delivery, as it is correlated with lower morbidity and mortality than caesarean sections (C-sections), [ 3 ...
Childbirth, also known as labour, parturition and delivery, is the completion of pregnancy where one or more babies exits the internal environment of the mother via vaginal delivery or caesarean section. [7] In 2019, there were about 140.11 million human births globally. [9]
Uterine contractions are a vital part of natural childbirth, [6] which occur during the process of labour and delivery, (typically this excludes caesarean section). These labour contractions are characterized by their rhythmic tightening and relaxation of the myometrium , the most prominent uterine muscle.
During sexual intercourse, sperm cells are ejaculated into the vagina through the penis, resulting in fertilization of an ovum to form a zygote. [1] While normal cells contain 46 chromosomes (23 pairs), gamete cells contain only half that number, and it is when these two cells merge into one combined zygote cell that genetic recombination occurs.
The vagina is a fibromuscular (made up of fibrous and muscular tissue) canal leading from the outside of the body to the cervix of the uterus. It is also referred to as the birth canal in the context of pregnancy. The vagina accommodates a penis during sexual intercourse.
In obstetrics, a cephalic presentation or head presentation or head-first presentation is a situation at childbirth where the fetus is in a longitudinal lie and the head enters the pelvis first; the most common form of cephalic presentation is the vertex presentation, where the occiput is the leading part (the part that first enters the birth canal). [1]
Vestibulodynia can be hormonal too, and potentially triggered by low-dose birth control pills, which may contribute to vaginal dryness by lowering testosterone levels (which is a huge factor in ...
In obstetrics, position is the orientation of the fetus in the womb, identified by the location of the presenting part of the fetus relative to the pelvis of the mother. . Conventionally, it is the position assumed by the fetus before the process of birth, as the fetus assumes various positions and postures during the course of chil
