The PCT examines sperm survival in cervical mucus during the pre-ovulatory period and determines whether sperm are migrating into the female reproductive system. It does not predict whether pregnancy can occur. The test is performed 1 to 2 days before ovulation, when estrogen-stimulated cervical mucus is abundant.
It lasts 1 to 4 days after birth, before easing to light "spotting". [7] [unreliable source?] Lochia serosa is the term for lochia that has thinned and turned brownish or pink in color. It contains serous exudate, erythrocytes, leukocytes, cervical mucus and microorganisms. This stage continues until around the tenth day after delivery.
Normal vaginal discharge is composed of cervical mucus, vaginal fluid, shedding vaginal and cervical cells, and bacteria. [1] The majority of the liquid in vaginal discharge is mucus produced by glands of the cervix. [1] [4] The rest is made up of transudate from the vaginal walls and secretions from glands (Skene's and Bartholin's). [4]
Diagram illustrating how the uterus lining builds up and breaks down during the menstrual cycle Menstruation (also known as a period, among other colloquial terms) is the regular discharge of blood and mucosal tissue from the inner lining of the uterus through the vagina. The menstrual cycle is characterized by the rise and fall of hormones. Menstruation is triggered by falling progesterone ...
The cervical canal is a pathway through which sperm enter the uterus after being induced by estradiol after penile-vaginal intercourse, [21] and some forms of artificial insemination. [22] Some sperm remains in cervical crypts, infoldings of the endocervix, which act as a reservoir, releasing sperm over several hours and maximising the chances ...
The cervical mucus plug (CMP) acts as a protective barrier by deterring the passage of bacteria into the uterus, and contains a variety of antimicrobial agents, including immunoglobulins, and similar antimicrobial peptides to those found in nasal mucus.The CMP inhibits the migration of vaginal bacteria towards the uterus, protecting against ...
The cervix remains soft after birth. The vagina contracts and begins to return to the size before pregnancy. For four to six weeks of the postpartum period the vagina will discharge lochia, a discharge containing blood, mucus, and uterine tissue. [11]
Records of basal body temperatures, especially, but also of cervical mucus and position, can be used to accurately determine if a woman is ovulating, and if the length of the post-ovulatory (luteal) phase of her menstrual cycle is sufficient to sustain a pregnancy.
