Exempel på hur man kan använda OVULATION i en mening

• Symptoms may include: goiter, poor length growth in infants, reduced adult stature, thickened skin, hair loss, enlarged tongue, a protruding abdomen, delayed bone maturation and puberty in children, mental deterioration, neurological impairment, impeded ovulation, and infertility in adults.
• Emergency contraceptive pills (ECPs), sometimes simply referred to as emergency contraceptives (ECs), or the morning-after pill, are medications intended to disrupt or delay ovulation or fertilization, which are necessary for pregnancy.
• Diagnosis requires a consistent pattern of emotional and physical symptoms occurring after ovulation and before menstruation to a degree that interferes with normal life.
• Pregnancy can occur with sexual intercourse after the start of ovulation, which can happen before the first menstrual period (menarche).
• In females, an acute rise of LH known as an LH surge, triggers ovulation and development of the corpus luteum.
• In the days leading up to ovulation the cervix responds to oestrogen by producing mucus capable of sustaining sperm survival.
• It is the remains of the ovarian follicle that has released a mature ovum during a previous ovulation.
• Embryos from 12 donor mares at 8 days of ovulation were recovered, scored, then transferred to 37 recipients mares who were tested for pregnancy after 7-10 days.
• Oogenesis results in the formation of both primary oocytes during fetal period, and of secondary oocytes after it as part of ovulation.
• The color and the number of notches on the horn may symbolize the number of moons or the number of menstrual cycles in one year, or the number of days from menstruation to ovulation.
• There is a laterality preference based on the specific oviduct and ovary used for ovulation; when only a single ovum is ovulated there is a pressure for the right ovary to overproduce a larger number of mature ova.
• Sperm development (spermatogenesis) and release of the egg from the ovaries (ovulation) may be impaired by hypogonadism, which, depending on the degree of severity, may result in partial or complete infertility.
• In contrast, the females of humans and a few other species that undergo hidden estrus have few external signs of fecundity, making it difficult for a mate to consciously deduce, by means of external signs only, whether or not a female is near ovulation.
• Levonorgestrel-releasing implant prevents pregnancy through multiple methods: by preventing ovulation, which means that no eggs are released for fertilization; by thickening the mucus of the cervix, which prevents sperm from entering; and by thinning the lining of the uterus, which makes implantation of an embryo less likely.
• At the time of puberty, women have approximately 200,000 to 300,000 follicles, each with the potential to release an egg cell (ovum) at ovulation for fertilization.
• Apart from fibrinolysis, plasmin proteolyses proteins in various other systems: It activates collagenases, some mediators of the complement system, and weakens the wall of the Graafian follicle, leading to ovulation.
• Fall lambing is generally not done as the lamb crop percentage is likely to be low; ewes often need hormone therapy to induce estrus and ovulation, and farm labor is often busy elsewhere during fall lambing.
• The Woodlands Coopworth is a strain within the Coopworth breed, characterised by an X-linked gene which increases ovulation by about 40%, and so contributes to greater fecundity.
• Clown loach reproduce in captivity only after hormonal stimulation of final oocyte maturation and ovulation.
• The underlying causes may include ovulation problems, fibroids, the lining of the uterus growing into the uterine wall, uterine polyps, underlying bleeding problems, side effects from birth control, or cancer.
