Childbearing years are from __
between ages 15 to 44 years old
Menstrual Cycle Phases:
A normal menstrual cycle ranges from 23-35 days (average = 28 days).
The start of bleeding (menses) is day 1 of the cycle. This indicates that the next cycle has begun. The remnants of the previous cycle (the thick, bloody endometrial lining) are sloughing off.
Menstruation typically lasts a few days (2-5 days). Changes in hormone levels cause the events that characterize the different phases of the menstrual cycle.
Menstrual Cycle Phases:
During what phase dose menses occur?
Follicular phase
- when the estrogen and progesterone levels start off low.
Menstrual Cycle Phases:
What are the phases of the Menstrual cycle?
1)
2)
3)
1) Follicular phase
2) Ovulatory phase
3) Luteal phase
Menstrual Cycle Phases:
The first ~14 days of the menstrual cycle, also called the ____________.
What is happening here is ________
During the end of this phase, what happens?
Follicular phase
that every follicle in a woman’s ovary there is an egg (oocyte - immature)
- in this phase FSH is helping to spur on the development of the follicle. Helping it mature and grow.
Approaching the end of the Follicular phase there is this rise in estrogen.
This rise in estrogen leads to a surge in (LH) luteinizing hormone AND (FSH) follicle stimulating hormone.
When we see that LH surge and that FSH that peak, this tells us that it is going to trigger ovulation about 24-36 hours later.
Menstrual Cycle Phases:
Ovulation:
- the release of the egg (ova) from the ovary.
Menstrual Cycle Phases:
The start of ovulation begins the ___________.
____________ is dominant in this phase.
Luteal (last) phase, which lasts ~14 days.
Progesterone.
Pregnancy Kits:
_____________ is released when a fertilized egg attaches to the lining of the uterus (called implantation).
A home urine test can detect pregnancy sooner if the women tests the __________________, when it is the highest.
(hCG) Human chorionic gonadotropin -
- detecting hCG in the urine or blood indicates pregnancy*
- first urine in the morning* when hCG is the highest
(hCG) human chorionic gonadotropin - tells us a woman is pregnant.
Fertility Awareness and Test Kits:
Ovulation kits predict the best time for intercourse by detecting LH in the urine. For someone trying to get pregnant and conceive a child.
- LH surge -> release of oocyte (egg) from the ovary into the fallopian tube.
- The egg lives for 24 hours and sperm can survive for ~ 3 days.
A positive ovulation test?
A person wishing to conceive should have intercourse when the LH surge is detected, and for the following 2 days (based on sperm survival of ~3 days).
- test will detect if patient has an LH surge
- which means, patient is going to have ovulation in the next 24-36 hours
- so have intercourse for the next 2 days to give yourself the best chance of becoming pregnant
LH - tells us when we are going to ovulate.
Preconception Health:
- focuses on steps to take to protect the health of the baby in the future.
- any woman planning to conceive (and all women of childbearing age) should:
1)
2)
3)
1) Increase their folic acid (folate, vitamin B9) consumption from a combination of dietary supplements and fortified foods (e.g. dried beans, leafy green vegetables, oranges). Before becoming pregnant.
- Folic acid supplementation: Adults are recommended to take 400mcg of dietary folate equivalents (DFE) per day to help prevent neural tube defects.
[During pregnancy this requirement increases to 600mcg DFE/day].
2) Lifestyle changes:
- No alcohol
- No illicit drugs
- Avoid smoking
- Keep vaccinations up to date
- Avoid toxic chemicals (hazardous drugs)
Contraception:
Fertility-Awareness Based Methods-
- 24% failure rate
- not very effective
- non-pharmacologic option
- essentially knowing your cycle, know when you are ovulating and making sure you are not having sex in that window.
Contraception:
- can be used until ready to conceive.
- a prompt return to fertility occurs when most contraceptives are discontinued.
- the only reversible contraceptive method that has a delay in return to fertility is the medroxyprogesterone injection.
Nonpharmacologic & OTC contraceptive methods:
Contraception:
Male condoms-
Female condoms-
Male condoms:
- 18% failure rate
- a thin latex or plastic sheath worn on the penis.
- OTC
Female condoms:
- 21% failure rate
- has a closed end at the top, which is the part that gets inserted into the vagina.
- OTC
[Never recommend oil-based lubricant for use with latex or non-latex synthetic condom.] Only recommend water or silicone-based lubricants.
Condoms- are the ONLY method that provide some protection with STDs. As long as they are latex or synthetic.
Contraception:
Spermicide-
[nonoxynol-9] - spermicide used in this country.
- 28% failure rate
- can be used alone or with other barrier methods
- not very effective alone, preferred with other contraceptive methods
- Do not use with anal sex, causes irritation
- can increase risk of STD/HIV transmission
- OTC
Contraception:
Phexxi-
(lactic acid, citric acid, and potassium bicarbonate, 1.8%, 1%, 0.4%)
- a prescription option (Rx)
- a vaginal gel that maintains an acidic pH (range 3.5-4.5), which is inhospitable to sperm and reduces their mobility.
- should NOT be used with vaginal rings or in those with a history of UTIs or urinary tract infections.
- comes in a box of #12 (5 gram) pre-filled single dose vaginal applicators.
