1. What are the differences between male infertility, impotence,
erectile dysfunction, and premature ejaculation?
Infertility is defined as the inability to establish a pregnancy
after trying to conceive for 1 year. Impotence or erectile dysfunction
is the inability of a man to achieve or maintain an erection. Premature
ejaculation is more difficult to define but is generally described
as recurrent ejaculation with minimal stimulation before the person
wishes. These conditions may be related in some patients or may
occur independent of each other. Men experiencing fertility problems
may be potent and men with erectile dysfunction may be fertile.
2. Which doctors specialize in treating male infertility?
Urologists are physicians and surgeons who treat genitourinary tract
disorders. Most general urologists have only basic knowledge and
training in treating male infertility. There is a subspecialty within
Urology known as Andrology which deals specifically with male fertility,
reproductive tract disorders and microsurgery. This requires an
intensive 1-2 year period of fellowship training after Urology residency.
There are only a handful of urologists who have completed this type
of training and are truly "experts" in this area. The
reason that this extra training is necessary is that the field of
Andrology is evolving rapidly and much of the surgery performed
to treat infertility needs to be done using an operating microscope
for best results. Microsurgery is a skill which takes time and constant
practice to perfect and maintain. A male infertility specialist
should dedicate more than half of his/her practice to only infertility
problems to remain current with information and skills. It is the
responsibility of YOU the patient to make sure the doctor you choose
is really a male infertility expert and avoid wasting precious time,
unnecessary lab tests, surgical procedures, misinformation, and
ensure the best possible results. Ask your doctor if he has completed
an Andrology and microsurgery fellowship, how much of the practice
is devoted to treating infertility, and ask to speak with other
patients if possible.
3. Is it possible to reverse a vasectomy?
Vasectomy reversal is not only possible but is highly successful
when performed by an experienced infertility micro-surgeon. Unfortunately
other doctors without these special skills will perform the surgery
themselves rather then referring the patient to an infertility specialist.
Once again it is incumbent upon the patient to make sure that his
doctor performs the procedure regularly and successfully. A good
idea is to ask to speak with some of his patients that have already
undergone the procedure. Studies have shown that the outcome of
surgery is so dependent on the surgical technique and the surgeon
that performs it that it is well worth making the extra effort in
going to a specialized center. Although failed vasectomy reversals
can be repaired, the first attempt at reversal is the easiest and
best opportunity for success.
4. With ICSI only a handful of sperm are needed, why should I have
a vasectomy reversal?
Both vasectomy reversal and ICSI/sperm aspiration are good alternatives
to father a child after vasectomy. They each have advantages and
drawbacks. In most situations vasectomy reversal offers the greatest
chance for pregnancy. It requires one procedure be performed only
on the man and couples can then try to get pregnant every month
the old fashioned way using "IBF" or what we call "in-bed
fertilization". ICSI on the other hand requires that both partners
undergo a procedure and the woman is stimulated with fertility drugs
to treat a "male problem". The costs of establishing a
pregnancy are three times greater with ICSI than with vasectomy
reversal. It is even less expensive to have a vasectomy reversal
and a repeat vasectomy (if desired) then to have ICSI. The advantage
of ICSI is the possibility for some couples to establish a pregnancy
quicker than with vasectomy reversal. We recommend ICSI/sperm harvesting
in those situations where vasectomy reversal would be difficult
or impossible, the female partner is of advanced reproductive age,
or when there is also a female factor contributing to the infertility.
Each couples' circumstances are unique and need to be addressed
on an individual basis. Our goal is to assist couples in having
a child of their own, regardless of the path they choose.
5. Does using a hot tub affect my fertility?
Excess heat applied to the testicles of animals does indeed cause
a decrease in sperm production. A study in California showed that
men who used hot tubs experienced q drop in sperm production. However,
when the heat is avoided for several months, sperm production should
return to normal. The production of sperm is a process requiring
approximately three months. Consequently, when any condition or
factor injurious to production of sperm is removed, a change in
sperm quantity or quality should not be expected for a minimum of
three months.
6. Does it matter what kind of underwear I wear?
The old wives' tale that tight underwear causes decreased fertility
has, perhaps, some basis in the truth. The truth is that excess
heat applied to the testicles can decrease sperm production. This
has been shown in men using hot tubs. However, the type of increased
heat produced by tight clothing and/or underclothing has not been
shown to elevate scrotal temperature. Hence, tight underwear has
not been shown scientifically to cause any increase in testicular
heat and is not thought to have any effect on sperm production.
Nevertheless, if you would like to try a change in clothing to see
what happens, there is really no reason not to try it.
7. Does masturbation affect fertility?
Masturbation is not different from normal intercourse in that an
orgasm causes ejaculation whether it is the result of masturbation
or sexual relations. When fertility is a concern, masturbation should
not be practiced around the time of the wife's fertile period. Theoretically,
this can decrease the sperm reserve in an individual with a low
or low-normal count and thus reduce semen quality at the time that
the highest quality is needed - when the wife is ovulating. However,
masturbation will not have a long-term injurious effect on the testes.
8. Should I be concerned about fertility if I have a venereal
disease?
In the male, most sexual transmitted diseases cause irritating symptoms
at the time the disease is active. Following the acute stage of
the disease, long-term problems with fertility is not common. However,
untreated venereal disease can cause infection of some of the accessory
sexual structures, such as the epididymis (the gland that collects
the sperm) or the vas deferens (the tube that transmits the sperm).
If these become infected by gonorrhea or chlamydia (common sexually
transmitted organisms) the result can be scarring which affects
fertility by blocking the transport system. Sperm production should
not be affected unless the disease process spreads to the testes.
9. May I use lubricant with intercourse?
Most lubricants used with sexual intercourse have a toxic effect
on the sperm. This can be a problem if the woman lubricates poorly
during sexual arousal and finds intercourse without use of lubricants
to be irritating and uncomfortable. If lubricants are used, they
should be used sparingly.
10. How often should I have intercourse?
The frequency of intercourse generally should be that which the
couple considers most enjoyable. However, during the time of the
moth when ovulation takes place, the most advantageous frequency
of intercourse is every other day (i.e., every 48 hours). The reason
for this interval is that sperm should survive for 48 hours within
the woman's reproductive tract and the egg should be subject to
impregnate for 12 to 24 hours. Intercourse every other day keeps
sperm along the course of the fallopian tube ready for contact with
the egg as it makes its descent from the ovary towards the uterus.
11. Does the use of drugs such as marijuana affect fertility?
A group of drugs or substances either ingested or present in the
environment that hurt sperm production are known as gonadoloxins.
Drugs which can adversely effect sperm production include alcohol,
marijuana, steroids used to induce weight gain in athletes, and
certain preparations, such as Azulfidine, taken for irritative bowel
disease. However, when these substances are discontinued, sperm
production should return to normal within three to six months. The
problem with substances such as alcohol and marijuana is that no
one is certain of the level at which they can be ingested without
affecting sperm production. Consequently, the use of these substances
should be minimized during the time that a couple is attempting
to establish a pregnancy.
12. What is the effect on fertility of working outside in
the heat?
Heat is bad for sperm production according to data gathered by applying
heat directly to the testicles. However, environmental heat, such
as that experienced by workers in the sunshine should not affect
sperm production.
13. Why is it that my semen analysis is different here than
in my first doctor's office?
Semen quality changes day to day, week to week and month to month.
There are also certain minor variations in laboratory techniques
that will result in differences in evaluation of the semen quality
from one office to another. However, the differences should not
be sufficient enough to make an abnormal semen normal or visa versa.
Usually, when the sperm production has once been adversely and seriously
affected, one's sperm count stays in the low range, no matter where
it is tested. A change of two or three million is not a significant
variation. However, in order to establish a good base line for future
therapy, at least three semen analyses should be collected. They
should all be collected with a minimum amount of variation, i.e.,
always after a 48-hour abstinence, and delivered to a doctor's office
within two hours of collection.
14. Why do I frequently have pain during my first urination
after ejaculation?
It is not unusual for the male to experience some burning (dysuria)
during urination following ejaculation. This is the result of friction
developed along the urethra (the lining of the penis) during the
act of sexual intercourse or masturbation. Urine moving along the
urethra creates a burning sensation. It should not be considered
a sign of any active disease or indicative of injury to the penis
but rather a natural event. However, if burning persists in the
absence of ejaculation or sexual contact, some type of infection
may be present.
15. Why do I have "clumps" in my ejaculate? Is
this normal?
The visible ejaculate is a combination of material from the testes,
prostate, and seminal Vesicles. The latter two are known as the
sex accessory glands in the male. At the time of ejaculation, the
seminal fluid is a gel. It will normally liquefy within 5 to 30
minutes. During the process of liquidation, the ejaculate may appear
lumpy. This is not abnormal and should not be considered a pathological
situation.
16. Does it matter what position we use during intercourse?
Positions during intercourse should not adversely affect fertility
and subsequent pregnancy. The loss of some semen from the vagina
is experienced by most women following intercourse and does not
indicate that enough semen is leaking out to prevent pregnancy.
However it is a good idea, if fertility has been a problem, to minimize
semen loss and maximize contact of the cervix with the seminal pool
within the vagina. This is achieved most conveniently if the woman
lies on her side with her knees brought up towards her chest following
sexual relations. This forces the cervix down into the vaginal pool
of semen which has been created. It is also helpful for the female
to minimize trips to the bathroom following intercourse by voiding
prior to sexual activity. The sensation of having to void following
intercourse usually is caused by irritation of the urethra, is normal
in nature, and should pass if the female merely waits.
