your reproductive system is wonderfully

complex yet the signals it gives you can

be quite simple helping you identify the

fertile and infertile times in your

cycle you may have noticed different

types of discharge throughout your

menstrual cycle the sensation that this

discharge produces at the vaginal

opening called the vulva also changes

this is because your cervix produces

different types of mucus in response to

changing hormone levels

your cycle begins with menstrual

bleeding when the lining of your uterus

called the endometrium is shed

following menstruation your cervix

becomes blocked by a thick plug of mucus

that prevents sperm from entering the

uterus this means that you are infertile

many women feel dry at the vulva during

this time other women notice a pattern

of discharge that feels and looks the

same day after day the number of days

that you experience this unchanging

pattern will determine the length of

your cycle in an average cycle this

pattern of infertility lasts for a few

days if your cycle is short you may not

experience any days of this infertile

pattern in a longer cycle you will have


early in your cycle the pituitary gland

in your brain begins to secrete a

hormone called follicle stimulating

hormone or FSH FSH stimulates the growth

of a group of follicles in your ovaries

each follicle contains an egg and a

bundle of surrounding cells that secrete

the hormone estrogen

estrogen activates the cervix to produce

the mucus essential for fertility this

is the start of the fertile phase the

fertile phase shown here using a baby

symbol begins a few days before

ovulation one type of mucus produced by

the cervix dissolves the plug which

means sperm can now enter the uterus

another type of mucus filters out

damaged sperm cells yet another type

nourishes the sperm so they can live for

up to five days in your reproductive


it forms channels which help the sperm

travel through your reproductive system

to meet and fertilize the egg

you become aware of your developing

fertility by the changes in the mucus

that you feel and see at the vulva you

will notice that you feel increasingly

wet and then slippery and you may see

mucus that becomes thinner and clearer

the last day of the slippery feeling is

called the peak of fertility it is very

close to the time of ovulation

as one follicle nears maturity the

pituitary gland is stimulated to release

a surge of another hormone called

luteinizing hormone or LH LH triggers

ovulation the release of the egg from

its follicle the egg is swept up into

the fallopian tube ready to begin its

journey towards the uterus if

fertilization doesn't occur the egg will

die within a day of ovulation but if the

egg meets any sperm along the way

fertilization can take place

after ovulation the empty follicle is

transformed into the corpus luteum the

corpus luteum produces a hormone called

progesterone progesterone prepares the

endometrium in case there's a fertilized

egg ready to implant it also causes the

mucus to thicken and the plug to begin

forming in the cervix again the day

following the peak you'll no longer feel

wet or slippery at the vulva by the end

of three days after the peak your

fertility for this cycle is over about

two weeks after ovulation a new cycle


we can now see how essential cervical

mucus is for fertility once you're

familiar with your patterns you'll be

able to identify your fertile and

infertile times this knowledge can help

you to achieve or avoid pregnancy at

your reproductive health as you'll be

able to recognize changes which might

need medical investigation this is

knowledge that every woman ought to have
