Antepartum Assessments & Care 1. Reproductive Cycle & Fertilization ● A nurse is teaching a woman about her menstrual cycle. The nurse states that ● Pro... liferation of the endometrium is the most important change that happens before the secretory phase of the menstrual cycle. The clinic nurse knows that the part of the endometrial cycle occurring from ovulation to just prior to menses is known as the secretory phases occurs from the time of ovulation to the period just prior to menses, or approximately days 15 to 26. ● ➢ The secretory phases occurs from the time of ovulation to the period just prior to menses, or approximately days 15 to 26. ➢ Amniotic fluid first appears at about 3 weeks. ➢ There are approximately 30 mL of amniotic fluid present at 10 weeks’ Reproductive Cycle: Menstrual Cycle 28 days MENSTRUAL CYCLE Ovarian Cycle: the maturation of the ova consisting of Follicular Phase - (from the 1st day of menstruation to 12-14 days) LH & FSH cause graafian follicle to mature producing Estrogen Ovulatory Phase - (begins when estrogen levels peak until oocyte released from graafian follicle) = OVULATION ^LH Luteal Phase - (begins after ovulation and lasts 14 days) ^ estrogen & progesterone If pregnant, know that the corpus luteum secretes estrogen & progesterone until placenta matures and assumes this function > If pregnant, corpus luteum will continue to secrete estrogen & progesterone until placenta matures > If NOT pregnant, corpus luteum degenerates = < in progesterone and beginning of menstruation Endometrial “Uterine” Cycle: changes in the endometrium of the uterus in response to the ovarian cycle Proliferative Phase - (occurs following menstruation ending with ovulation) endometrium preparing for implantation =more THICK & VASCULAR Secretory Phase - (after ovulation and ends with onset menstruation) = continues to THICKEN ^progesterone Menstrual Phase - sloughing off of the endometrium = PERIOD . Fertilization: “Conception” occurs when the sperm nucleus enters the nucleus of the oocyte within the outer third of the fallopian tube. The fertilized egg is then called a ZYGOTE and contains a diploid number of chromosomes = 46 gestation, and this amount increases to approximately 800 mL at 24 weeks’ gestation. After that time, the total fluid volume remains fairly stable until it begins to decrease slightly as the pregnancy reaches term. 2. Infertility ● Infertility: the inability to conceive or maintain a pregnancy after 12 months of unprotected sexual intercourse 6 months for women older than 35 y.o ● ○ ○ ○ ○ ■ ■ ■ ■ ○ ■ > Causes 1/3 Male Factor Endocrine - < in LH, FSH, Testosterone Spermatogenesis - effects of gonadotoxins Gonadotoxins include: drugs, infections, systemic illness, heat exposure, pesticides and radiation to the pelvic region.
