Questions about the organs, cells and hormones associated with sexual reproduction.

Can sperm back into bladder?

Yes. As part of prostate removal surgery, the duct that brings sperm to the prostate is rerouted to deliver to the bladder.

What is a not function of the female reproductive system?

Production and storage of oogonia.

(Oogonia are produced bythe female reproductive system.)

How long does it take the egg to travel down the fallopian tubes?

wow. i have no idea. but ive heard sperm can stay alive inside of you for 3 days... It only takes about 45 minutes. So my suggestion for falling preg is to stay laying down for about this amount of time. Yes, sperm can live up to 3 days inside a woman. But once the egg is fertalized, it takes about 5 days for it to travel down the tube and to implant itself into the uturus.

Can a women with male parts get another women pregnant?

Testosterone doesn't cause pregnancy in itself. Even if it were possible for a high level to produce sperm in women, the storage and delivery system is missing!! There's no way this amazing theory could ever work. Human bodies are way too complex and intricately made to be easily changed.

Who was the proponent of reproductive health bill?

In Congress, Mr. Edcel Lagman and the Gabriela Party, among others. In Senate, Sen. Miriam Defensor Santiago.

How do yeast reproduce sexually asexually?

It goes through a process called "budding". Budding is when one cell will brake into two cells, then four, etc. Since it's only one cell it's asexual not sexual.

Both fallopian tubes are patent with bilateral peritoneal spillage?

In the context of a hysterosalpingogram, opaque tubes and peritoneal spillage means that the tubes are open. The dye showed up in both tubes, and was able to make it to the end of the tube without blockage.

Is the primary oocyte diploid?

92

In women, gametogenesis begins in fetal life, but is arrested in prophase of meiosis I for years until just before ovulation. This arrested oocyte is called the "primary oocyte". The human genome consists of 23 chromosomes, and normal somatic cells in humans have two of each chromosome (2N) in the resting state. Since the DNA in the primary oocyte has already replicated and but hasn't undergone division yet, the cell contains double the number of chromosomes of the original cell. Therefore the primary oocyte has 92 chromosomes (4N).

Keep in mind though, that just before ovulation, the cell will complete meisois I and be released as 2N (the other 2N is split off as the 1st polar body). This released cell (secondary oocyte) which is now 2N is arrested in metaphase of meiosis II until fertilized, where it will release a second polar body (which now only has 1N). The fertilized egg therefore has two copies of chromosomes, 23 from mother (from the original 92 you started out with), and 23 from the sperm.

After cutting the fallopian tube is there any of having a baby?

Due to the risk of infection, the Fallopian tubes are ligated . . . tied off with an appropriate fine cord. It is not impossible for this to be reversed, but there is a lot of expensive surgery involved that may or may not work.

What does the bulbourethral gland produce?

The main function of the bulbourethral or cowper's gland is to produce and release the "pre-cum" to rid the urethra of any acidic urine. The clear fluid neutralizes urine in the urethra so that when a man ejaculates, the sperm in the semen are not destroyed by acidic urine leftover in the urethra. The whole purpose of ejaculation is to send healthy sperm out of the male and into the female reproductive system for fertilization; this can't happen if the sperm come into contact with acidic fluids.

The bulbourethral glands (also known as the cowper's glands) are male sexual glands. They are located below the prostate and discharge a component of the seminal fluid into the urethra. During sexual intercourse each gland produces a secretion known as pre-ejaculate. This fluid helps to lubricate the urethra for spermatozoa to pass through, it neutralizes traces of acidic urine in the urethra, and helps flush out any residual urine or foreign matter. It is possible for this fluid to pick up sperm, and carry them out prior to the next intercourse.

What is the muscle in the uterus called?

The uterus is made up of smooth, or involuntary, muscle. It is not under conscious control.

If you release two eggs and only one gets fertilized can you still bleed as long as a normal period?

If sex occurs in the days leading up to ovulation and one egg were to be fertilized it would prevent a period from occurring. It is impossible for a woman to have a 'period' after conception has occurred. Although spotting in early pregnancy is common, it would not be considered to be menses.

What part of the female reproductive system does fertilization in humans normally occur?

  • Fertilization happens in the fallopian tubes.
  • The fallopian tubes lie in the pelvic portion of the abdominal cavity and each tube reaches from an ovary to become the upper part of the uterus. This funnel-shaped tube is about three inches in length; it carries eggs and sperm, and is where fertilization of the egg takes place. The larger end of the funnel is divided into feathery, finger-like projections, which lie close to the ovary. These beating projections, along with muscle contractions, force the ovum down the funnel's small end, which opens into the uterus. After sexual intercourse, sperm swim up this funnel from the uterus. The lining of the tube and its secretions sustain both the egg and the sperm, encouraging fertilization and nourishing the egg until it reaches the uterus.

What is the organ that delivers semen to the female reproductive tract?

The penis is the organ than delivers semen to the female reproductive tract during sexual intercourse.

What are men reproductive cells called?

Men's reproductive cells are called, "Spermatazoa" (spurm-uh-tuh-ZOE-uh) A single cell is called a, "Spermatazoon" (spurm-uh-tuh-ZOE-on)

For short, both are often called, "Sperm cells". Sperm cells are very, very tiny, needing a microscope to even see them. They each have a long 'tail' called a flagellum used to swim to where they need to go.

What are different types of diseases and the preventive measures?

The only way to not get a disease ever is by not being alive.

There are genetic diseases, for which the only preventable measure is to prevent the parents from having children (some times only one parent is needed to carry the condition such as diabetes and other times both need to carry the gene).

There are airborne diseases, for which the only preventable measure is to wear a mask N95 24/7 (their lifespan is only 8 hours) or to live in a bubble.

There are fluid-borne diseases, like herpes (transmitted by kissing a person with a latent virus) , "hepatitis A" by eating contaminated foods/water and sexually transmitted diseases (hiv, chlamydia, etc) which can only be avoided by not having sex at all (condoms are 99.99% effective)

There are the ones transmitted by direct contact, like the eating flesh bacteria, in contact with an open wound, cold (the virus can live in a surface outside the body for hours and then re-entering via mucous surface such inside the nose or the eye or inside the mouth). Wash your hands and take proper care of open wounds.

Most of the people have immune systems, if the body doesn't get sick it will eventually over react to harmless things such as pollen, dust, pet hair (yes, that's right, allergies). Use it or loose it.

What is the role of hormones in human reproduction?

The male is in posession of the Testes, which produce sperm. Sperm can have either chromosone which results in the gender of the baby - X, or Y. You only need one Y chromosone for the child to result in a male, and two X for a female to be produced. There is a 50/50 chance of either. There are fewer sperm carrying X but they are faster than the sperm carrying Y, thus the chances even out. The female 'sex cell' or egg always carrys the X chromosone, thus only two pairings can result;

Female - XX

Male - XY

When the two nuclei of the egg and sperm cell unite, they form the Zygote, which divides and forms stem cells (Unspecialised cells found in the spinal cord in adult life), which specialise as the embryo grows.
