Reproductive System

The nine parts of the male and female reproductive system that are similar or exactly the same include the gonads (testes and ovaries), gametes (sperm and egg cells), and structures like the fallopian tubes (oviducts) and hormones such as estrogen and testosterone.

if it is fertilized by sperm it becomes a zygote that embeds itself into the lining on uterus The placenta, which is especially prepared for this event once a month

if it is not fertilized it breaks down after a couple of days which signals for the uterus to dispose of the lining in what is seen as menstrual bleeding.

Cilia lining the fallopian tubes help propel sperm through the female reproductive system. The contractions of the smooth muscle in the fallopian tubes also aid in moving sperm towards the egg for fertilization.

Improved answer:

A technique in which the male and female germ cells required to begin formation of a human embryo are injected into a woman's fallopian tubes of the female for fertilization. This technique is one of the methods doctors use to overcome infertility, the inability of couples to produce offspring on their own.

Gametes (germ cells) in males are the spermatozoa, or sperm, and those in females are ova, or eggs. After a sperm fertilizes an egg in the fallopian tubes, the egg implants itself in the uterus (womb), a hollow organ that lodges and nourishes the embryo during its development.

The term "intrafallopian" means "inside the fallopian tubes." ("Intra," a Latin word, means "within" or "inside.") Thus, in the GIFT technique, fertilization takes place inside the body of the female. By contrast, in the technique of in vitro fertilization (IVF), eggs are fertilized outside the body.

"Gamete" is derived from the Greek word "gamete" (wife) and "gamein" (to marry).

sperm

or an egg. Each contain 1/2 the total DNA of a normal cell. The sperm and egg combine to put these two halves together and create a new DNA combination that is unique to the individual (unless they have an identical sibling/s)

STDs can cause inflammation and damage to the reproductive organs, leading to conditions like pelvic inflammatory disease, infertility, ectopic pregnancies, and increased risk of miscarriages. Some STDs can also be transmitted to a fetus during pregnancy or childbirth, impacting the health of the newborn.

Uterus -is the place where babies are held during pregnancy. The uterus cleanses itself through monthly menstruation.

Ovaries houses and produces female eggs

cervix---supports the female organs

fallopian tubes transports eggs

vagina female sex organ

The prostate gland is not a paired accessory gland of the male reproductive system. It is a single, unpaired gland located beneath the bladder and surrounds the urethra.

• The external male genitalia are the penis and the scrotum, which contains two testicles.
• The internal male genitalia includes the remaining structures of the male reproductive system.

The monthly cycle of changes that occurs in the female reproductive system is called the menstrual cycle. This cycle involves the maturation and release of an egg, preparation of the uterus for potential pregnancy, and shedding of the uterine lining if pregnancy does not occur.

The uterus is the part of the female reproductive system that nourishes and develops the fertilized egg. After fertilization, the egg implants in the lining of the uterus where it continues to grow and develop into a fetus.

Smokeless tobacco does not affect the reproductive organs of either male or female. It contains nicotine, a mild stimulant, which has similar effects of caffeine on the cardiovascular system, but other than that it is basically harmless (see tobaccoharmreduction.org for more information on the risks associated with smokeless tobacco). The reason for its benignness compared to smoking is that it does not contain the thousands of chemicals and carcinogens that a lit cigarette does.

Cigarettes are cancerous because of the combustion. The moment a cigarette is lit on fire, thousands of chemicals and carcinogens are created and inhaled into the lungs (a sensitive organ that bypasses many of the body's natural defenses). Smokeless tobacco is absorbed through the tissues of the mouth, and does not contain the thousands of chemicals found in smoke. Many public health sites claim that smokeless tobacco causes cancer, however, this is rarely backed up (look for references to studies for claims like these; there are rarely any at all and those that are referenced are very old or poorly done). If I could point you to one excellent study on the effects of smokeless tobacco and cancer it would be this recent meta-analysis of the majority of good research done thus far, which can be found here: http://www.biomedcentral.com/content/pdf/1741-7015-7-36.pdf

According to the National Cancer Institute, there is a definite cause and effect between use of smokeless tobacco and cancer of the oral cavity. Smokeless tobacco has 28 chemicals that have been found to cause cancer. See the related link for more information.

Urethra APEX_

primarily, male testes = testosterone, female ovaries = estrogen

If only half of the females can reproduce, the species' population will gradually decline over time, as the reproduction rate will be lower than necessary to sustain the population. Factors such as genetic diversity, environmental conditions, and competition with other species will also impact the species' survival. Ultimately, without a sufficient number of females reproducing, the species may face extinction.

The hormone responsible for differentiation of the male reproductive organs during fetal life is dihydrotestosterone (DHT). It is derived from testosterone and plays a key role in the development of male external genitalia.

The urethra serves as the passageway of urine in both males and females.

The main function of the seminal vesicles is to produce and store fluid that makes up a significant portion of semen. This fluid provides nutrients and protection for sperm, aiding in their motility and ability to fertilize an egg during sexual reproduction.

The fornix is a recessed area in the upper vagina where the cervix protrudes into the vaginal space. It is divided into anterior, posterior, and lateral fornices and is important for gynecological examinations as well as during sexual intercourse.

The prostate gland is at particular risk after middle age. Conditions such as prostate enlargement and prostate cancer become more common as men age. Regular screenings and check-ups are important to monitor the health of the prostate.

Human chorionic gonadotropin (hCG) maintains the viability of the corpus luteum in early pregnancy. hCG is produced by the developing placenta and signals the corpus luteum to continue producing progesterone, which is essential for maintaining the uterine lining to support a pregnancy.

The human sex cell or human gamete has half the number of cells that any other normal human cell would have. A normal human cell (the one from your skin, mouth, lung, liver, sex organs, etc.) has 23 pairs of chromosomes and as such are called diploid cells. The sex cells are haploid having only 23 number of chromosomes as they unite with another haploid cell to create a normal cell with complete set of 23 pairs of chromosomes. The 23rd chromosome on a male human gamete is either the X or the Y chromosome while on the female gamete it is always the X chromosome.

Advantages-

1. Large numbers of offspring are reproduced very quickly from only one parent when conditions are favourable.

2. Large colonies can form that can out-complete other organisms for nutrients and water.

3. Large number of organisms mean that species may survive when conditions or the number of predators change.

4. Energy is not required to find a mate

The female reproductive system interacts with the endocrine system through hormone regulation, the nervous system for sexual arousal and response, and the circulatory system to supply nutrients and oxygen to reproductive organs. Additionally, the immune system plays a role in protecting the reproductive system from infections.

yes, the other two glands in the male reproductive system are the Cowper's gland and the seminal vesicles
