infertility infertility affects 15% of
00:06
reproductive age couples in the United
00:07
States there are medical psychosocial
00:09
financial and ethical considerations
00:12
that are all issues pertaining to the
00:13
discussion of infertility this video
00:15
will discuss infertility from the
00:17
standpoint of a heterosexual couple and
00:19
it is important to recognize that
00:20
fertility treatments offer the
00:21
opportunity for Parenthood too many
00:23
non-heterosexual individuals and couples
00:25
the objectives of this video are to
00:27
define infertility and list the causes
00:29
of male and female infertility describe
00:31
the evaluation and initial management of
00:34
an infertile couple describe the
00:36
psychosocial issues associated with
00:37
infertility describe management options
00:40
for infertility describe ethical issues
00:43
confronted by patients with infertility
00:44
and lastly describe the impact of
00:47
genetic screening and testing on
00:48
infertility associated treatments let’s
00:51
start with some basic definitions
00:52
infertility is defined as the failure of
00:54
a couple to conceive after 12 months of
00:56
frequent unprotected intercourse for con
00:59
nobility is the probability of achieving
01:00
a pregnancy in one menstrual cycle it is
01:03
estimated to be 20 to 25 percent in
01:05
healthy young couples after 12 months of
01:07
unprotected intercourse eighty-five
01:09
percent of couples will achieve
01:10
pregnancy what are the possible causes
01:12
of infertility let’s start with the
01:14
basics there needs to be production of a
01:17
good lewisite and production of a good
01:21
sperm the oocyte and sperm need to meet
01:27
to generate an embryo and this embryo
01:32
needs to make it to the uterine cavity
01:34
and successfully implant into the
01:36
endometrium what are the potential
01:39
causes that negatively affect this
01:41
process male factors account for 20%
01:43
female factors account for 65% and there
01:46
are unexplained or other conditions in
01:48
15% let’s start with male factors the
01:52
male needs to produce a good sperm thus
01:54
the evaluation of male infertility
01:55
involves a semen analysis it is obtained
01:58
by masturbation after two to three days
02:00
of abstinence a semen analysis evaluates
02:03
the volume sperm concentration motility
02:05
rapid progression motility and normal
02:08
morphology if the results are abnormal
02:11
then the semen analysis should be
02:12
repeated and a
02:13
assistant Li abnormal the malefactor
02:15
should be evaluated by urologist or
02:17
reproductive endocrinologist who
02:19
specializes in male infertility let’s
02:21
now move to female factors first there
02:24
needs to be production of a good Oh a
02:25
site a good history can often help you
02:27
determine if a woman is ovulating each
02:29
month a history of regular predictable
02:32
menses suggests of the Tori cycles
02:35
remember that after ovulation there is
02:37
an increase in progesterone and this can
02:39
cause symptoms such as abdominal
02:40
bloating weight gain and breast
02:42
tenderness in the luteal phase of the
02:44
cycle in addition the progesterone
02:45
causes a slight increase in body
02:47
temperature so women can monitor their
02:49
ovulation by checking their daily
02:51
temperature which is known as basal body
02:52
temperature charting alternatively women
02:55
can purchase ovulation predictor kits
02:57
which assess ovulation based on the
02:59
increased LH production which can be
03:01
detected in urine
03:02
these ovulation predictor kits can be
03:04
quite expensive however in order to
03:06
achieve pregnancy a woman has to ovulate
03:08
and she has to ovulate a quality OA site
03:11
common causes of ovulatory dysfunction
03:14
and reproductive age women include
03:16
polycystic ovarian syndrome or PCOS
03:18
thyroid disorders and hyperprolactinemia
03:20
a woman’s age also has a significant
03:24
impact on ovulation and OSI quality as a
03:27
woman ages
03:28
unfortunately sodor sites remember that
03:30
a female has at 20 weeks in utero about
03:33
6 to 7 million oay sites and she is born
03:36
with about 1 million u.s. i’ts she has
03:38
about 400,000 at the time of puberty and
03:40
there is a more rapid depletion starting
03:42
at around age 38 thus there is a marked
03:45
reduction of fecund ability in a woman’s
03:47
late 30s let’s now talk about what
03:50
happens after ovulation here’s the ovary
03:52
and the OA site which gets picked up by
03:56
the fallopian tube and fertilization
04:02
occurs in the ampulla a portion of the
04:05
fallopian tube the embryo will then
04:08
enter the endometrial cavity
04:10
approximately 5 days after fertilization
04:12
this process can be impaired if there is
04:15
damage to the fallopian tube by prior
04:17
pelvic inflammatory disease or abdominal
04:19
or pelvic surgeries a history or cell
04:21
pentagram evaluates the fallopian tube
04:24
patency for this procedure contrast
04:27
is injected into the uterine cavity note
04:29
the dark contrast filling the
04:30
triangular-shaped uterine cavity if the
04:33
fallopian tubes are paitent then the dye
04:34
will travel through both of the tubes
04:36
this HSG demonstrates normal fallopian
04:39
tubes for the dye travels all the way
04:41
through both of them uterine anomalies
04:44
are surprisingly uncommon causes of
04:46
infertility if there is a history such
04:48
as abnormal bleeding pregnancy loss
04:50
preterm delivery or previous uterine
04:53
surgery then assessment of the uterus is
04:55
important let’s now talk about
04:57
management options we have to go back to
05:00
our basic causes of infertility male
05:02
factors female factors and unexplained
05:04
or other conditions in order to
05:06
optimally try to achieve pregnancy we
05:08
need to think about how best to correct
05:10
any or all of these factors ovarian
05:12
stimulation these agents will stimulate
05:15
and effectively improve ovulation
05:17
clomiphene citrate is a selective
05:19
estrogen receptor modulators
05:21
which competes for estrogen receptors at
05:23
the level of the hypothalamus and
05:24
pituitary this leads to increase granada
05:27
trope and release from the pituitary
05:28
which stimulates increased follicular
05:31
development from the ovaries there is an
05:33
approximate 10% risk of multiple
05:35
gestation with clomiphene citrate
05:37
similarly controlled ovarian
05:39
hyperstimulation with purified human
05:41
gonadotropin stimulates the ovary to
05:43
increase follicular development there is
05:46
a 25% incidence of multiple gestation
05:48
with purified gonadotropins with
05:51
intrauterine insemination ejaculated
05:53
semen is washed to remove prostaglandins
05:55
bacteria and proteins and suspended in a
05:57
small amount of medium a catheter is
05:59
advanced through the cervix into the
06:01
uterine cavity let’s now move to
06:03
assisted reproductive technologies in
06:05
the United States in vitro fertilization
06:07
or IVF accounts for 99% of all AR T
06:11
procedures the IVF process involves
06:13
ovarian stimulation to produce multiple
06:15
follicles then there will be retrieval
06:17
of the oocytes from the ovaries lewisite
06:20
fertilization and embryo incubation will
06:22
occur in the laboratory and then there
06:24
will be transfer of embryo or embryos
06:26
into the woman’s uterus through the
06:28
cervix there is an approximate 30
06:30
percent risk of multiple gestation with
06:32
IVF and this will of course depend on
06:34
the number of embryos that are implanted
06:35
into the uterus the indications for IVF
06:38
include blocked or absent fallopian
06:40
tubes a history
06:41
of tubal sterilization severe pelvic
06:43
adhesions severe endometriosis pour-over
06:45
and response to stimulation severe male
06:48
factor infertility and failed treatment
06:51
with less aggressive therapies the
06:52
success rates for IVF will depend on the
06:55
etiology of the infertility
06:57
pre-implantation genetic diagnosis is
06:59
the genetic profiling of embryos prior
07:01
to implantation for example if a patient
07:04
knows that she or her partner is a
07:05
carrier for a disease such as cystic
07:07
fibrosis or ty Sachs disease and the
07:09
embryo can be tested for this prior to
07:11
implantation there are risks to the
07:14
embryo during the biopsy procedure which
07:16
points to the ethical questions of fetal
07:18
selection what if a patient desires to
07:20
have pre-implantation genetic diagnosis
07:22
performed because they do not want a
07:24
certain gender child the discussion of
07:27
infertility and assisted reproductive
07:29
technologies should also include the
07:31
discussion of ethical issues that are
07:32
confronted both by patients and
07:34
providers with infertility therapy
07:36
should insurance companies be required
07:38
to pay for IVF should there be an age
07:41
limit for which IVF should not be
07:42
offered there is always the question and
07:44
costs of higher order multiple births
07:46
what about egg banking young women can
07:49
be recruited to donate eggs and through
07:51
this process some argue that women are
07:53
not counseled adequately about the risks
07:55
of ovarian hyperstimulation syndrome and
07:57
can and should a physician legally and
07:59
ethically decline ovulation induction
08:01
for patients with diminished ovarian
08:03
reserve when chances of successful
08:05
pregnancy or futile these questions are
08:08
complex and many factors including
08:10
social class gender race healthcare
08:12
utilization and access need to be
08:14
considered in weighing these complicated
08:15
decisions let’s conclude by discussing
08:18
psychosocial stress associated with
08:20
infertility the amount of social support
08:23
that a patient receives can have
08:24
significant effects on stress levels
08:26
compared to white and Asian women black
08:28
women were less likely to report
08:30
encouragement for treatment from their
08:31
partners and family members it is
08:33
important to recognize that the
08:35
psychological stress exists and to
08:37
determine the patient’s support network
08:38
and help our patients find resources to
08:41
help them through this process this
08:43
concludes the aapko video on infertility
08:44
we have described evaluation at initial
08:47
management of an infertile couple and
08:48
described the ethical and psychosocial
08:50
issues associated with this common
08:52
condition
