If you asked
someone, "What differences are there between the female and male
reproductive system?", there would be many responses to that. Yes, there
are many differences between the two, but there are some slight similarities,
too. Weird, isn't it?
But first, let us
take a look at what some of the differences are.
When you take a
take a look at the penis and vagina, there are many differences between the
two, anatomy wise. For example, the majority of the male reproductive system is
located outside of the body; penis, scrotum, and the testes. However, in the
female, the anatomy of the female reproductive system is inside the body; fallopian
tubes, ovaries, uterus, etc.
Although
anatomically different, the systems between the male and female is similar,
with some slight differences. According to WebMD, both the male
and female
reproductive system are designed to produce and transport sperm and egg,
respectively. It's like a train, bus, or any other transportation system, going
from point A to point B.
However, the way
in which the sperm and egg are transported are different.
For males:
1. Sperm is
produced in the testes
2. Sperm goes to
epididymis to mature
3. Mature sperm
travels through the vas deferens
4. Mature sperm
gets coated with seminal fluid from seminal sac (now mature sperm can be
considered semen)
5. Semen goes into
the urethra and is ejaculated.
But, for women:
1. All egg in
ovaries are already produced before birth
2. During the menstrual
cycle, hormones are released and stimulate a small amount of eggs to grow and
mature
3. When the eggs
are ready, only one is released from the ovaries and is captured by the ends of
the fallopian tubes (finger-like)
4. The egg makes
its way down the fallopian tube. This is where one of two processes can occur,
depending if the egg is fertilized by the sperm or not.
*As for this post,
I will be focusing on the process where fertilization does not occur*
5. The
unfertilized egg continues to travel down the fallopian tube and goes into the
uterus.
6. Since the egg
is not fertilized, the outer-most lining of the uterus is not needed, and is
shed along with the unfertilized egg, which then is released out the vagina,
and is known as a "period".
7. This process
will continue monthly until the women becomes pregnant, which afterwards will
start this cycle again, or when the women goes through menopause.
As you can see,
both reproductive systems are similar, in that the sperm and egg travel through
the system, but the system itself differ between the two sexes.
Another way in
which these two systems are similar, is in the surgery to become infertile
(i.e. vasectomy for men, and tubal ligation for women). Both surgeries stop the
process of sperm or eggs travelling to the area in which its supposed to go to.
Therefore, making the man or woman infertile.
However, the
procedure is a lot less invasive for a man, than for a woman. For men, according
to the
Urology Care Foundation, the surgeon only needs to find the vas deferens
(tube where sperm travels to become semen), and make a slight incision.
Although for women, according to Mayo
Clinic, the surgeon has to open her up to get into where the fallopian
tubes are located.

Is there anything new
or surprising that you learned?
I really love how you number the step because that made the whole blog readable.
ReplyDeleteI have a question, once the vas deferens is cut, can you reconnect it later on?
You can reconnect the tied up vas deferens. It's called a vasectomy reversal. The part where the vas deferens were once cut and tied together, is cut off and reconnected, so that the sperm will be able to travel through it.

This was a great refresher, since i haven't taken a Biology class in a while ^^
