Genetic Technology and Artificial Insemination

Genetic technology is one of the many technological advancements that the world has made recently. This technique facilitates the development of novel traits by rapidly and readily altering DNA in a variety of ways. Utilizing this method, genetic material or genes are modified. These days, scientists are able to learn about genes, including what they are, how they work, and how DNA may be added, removed, or changed. All living things include genes, which are passed down from one generation to the next. Codified instructions found in genes are utilized in the synthesis of proteins and in the transmission of genetic traits.

The act of altering genes through knowledge of genetic expression, using naturally occurring genetic variety, and transferring genes to new species is known as genetic technology. Genetic engineering is one of the technologies that modifies an organism's DNA structure using laboratory-based methods. Another name for it is genetic modification. Through the addition or deletion of a gene or the modification of a single nitrogen base pair (A-T or C-G), a new characteristic is created in the DNA. Gene variations created through genetic engineering may pass down to subsequent generations. One significant use of genetic technology is the identification of genes and their functions. In molecular biology and biotechnology, genetic technology plays a significant role. With the use of DNA sequencing data on a plant's structure, function, process, etc., it has become feasible to alter and manage some plant properties. Currently, genetic technology based on gene expression, transgenic technology, and molecular markers is widely used in agricultural production. It has demonstrated great potential to increase agricultural quality and yield, decrease losses from biotic and abiotic factors, and increase an organism's ability to reproduce. The key to ensuring the long-term viability of agriculture is to employ these cutting-edge DNA technologies, which have enormous promise and necessity. These days, forensic science is the main area where DNA technology is applied. DNA testing is a tool used to look into a variety of criminal situations.

Role of DNA Testing in Various Investigations

The technology for DNA testing has made it simpler to look into different criminal cases and find the guilty. Paternity and criminal investigations are the two main uses of DNA testing. DNA testing is a delicate and intricate process, yet as a scientific procedure, it works well to prove facts. Significant errors can result from even a small mistake. Thus, extra care must be taken during the collection and transportation of samples in order to ensure that DNA testing is trustworthy, equitable, and efficient. Additionally, samples need to be shielded from contamination.

Artificial Insemination

These days, fertilization may occur without male and female creatures mating, thanks to technological advancements. The technique of gathering semen from faraway males and inseminating it into the bodies of female organisms has significantly grown in the modern era in order to produce children of sophisticated varieties. Artificial insemination, then, is the process of harvesting semen from males of advanced breeds and utilizing machinery to facilitate its timely insertion into the female reproductive system. It has been discovered that the offspring created via this method are just as normal as those created through natural mating. In this procedure, wholesome sperm from the male is taken out and allowed to enter a healthy female's uterus for fertilization at the appropriate time using artificial means.

"The Italian scientist Lazzaro Spallanzani conducted the first study on the artificial insemination of domestic animals on dogs in 1784."

His research demonstrated that fertility is found in the tiny sperm that float in semen rather than in the liquid portion of the semen. The primary goal of artificial insemination is to transfer an advanced-breed male's sperm to a female that is ready for conception in order to create a high number of advanced progeny. Farmers that raise animals can avoid the hassle of raising pricey males with unique traits by using this strategy. Additionally, this improves the financial standing of farmers. Currently, many animals, including cows, buffaloes, goats, sheep, and others, mate artificially rather than naturally. This is a secondary reproduction technique that is being used all over the world. This kind of breeding is a helpful method for enhancing an animal's genetic quality.

Advantages of Artificial Insemination

Artificial insemination has many advantages compared to natural mating. Some of them are listed below:

1. Rearing males for breeding is not necessary, saving rearing costs.
2. It facilitates the prevention of infection and illness transmission during mating.
3. The male's fertility is confirmed by testing and examining the semen once it has been collected.
4. Even after the male's death, specially collected semen can be put to use.
5. It is simple to carry collected semen across great distances for fertilization.
6. By using this technique, harm to the male or female during conception can be avoided.
7. The rate of fertilization is accelerated by this technique.
8. Maintaining accurate records of reproduction is beneficial.

Disadvantages of Artificial Insemination

1. It requires specialized equipment and personnel with proper training.
2. It takes longer than in-vitro breeding.
3. If the equipment used for artificial insemination is not thoroughly cleaned, reproduction may not occur, or there may be an infection.

In vitro Fertilization (IVF)

Let us know

Lesle Brown, a resident of Manchester, England, endured years of suffering as a result of her fallopian tube obstruction. In November 1977, she had an experimental IVF operation to solve it. For this, an adult ovum was removed from her ovary and combined with her husband's sperm in a lab dish to create an embryo. A few days later, the embryo was placed in her uterus. A decade prior, IVF research was being conducted by scientists Robert Edwards and Patrick Steptoe. Brown was the subject of a thorough inquiry once the media learned of her conception. Then, on July 25, 1978, Lesle Brown had a cesarean section to give birth to her daughter. Louise Joy Brown is her daughter, who is  the first child in the world to be borne by in vitro fertilization.

In Nepal, IVF technology began in 2004 in Om hospital through the establishment of an IVF center. On March 3, 2005, Rajendra Tamang and Sandhya Tamang gave birth to a baby named Om Mani Tamang as Nepal's first test-tube baby through this process.

The most successful form of assisted reproduction technology is IVF. This approach involves a sophisticated set of steps meant to assist couples dealing with genetic issues and decreased fertility. The conception process used in IVF is not the same as that of traditional sexual relations. The child who was born via IVF is healthy on the inside and out. Because IVF can be performed using a couple's own ovum and sperm or, in the event that the couple experiences difficulties with ovum and sperm production, egg and sperm from a known or unknown donor, the traits of the kid produced via this technique may or may not match those of his parents. In in vitro fertilization (IVF), a mature ovum from the female ovary is removed, preserved in a petri dish, and combined with the male sperm in a modern laboratory. After a few days, the fertilized ovum is moved to the female's uterus, or womb. It takes about three weeks for a complete cycle. However, depending on the severity of the issue, it can take longer. Like in a typical pregnancy, the embryo develops in the woman's uterus.

Advantages of IVF

1. For couples who are unable to conceive because of a variety of conception-related issues, in vitro fertilization (IVF) is the most effective way of conceiving.
2. It permits conception through the use of donor sperm and ovum or the sperm and ovum of the couple.
3. Compared to other assisted reproductive methods, it has higher success rates.
4. It helps to resolve issues pertaining to the child's different genetic abnormalities.
5. This method can address hereditary issues, including infertility.
6. It lowers the chance of miscarriage and boosts fertility.
7. It raises the likelihood of having a child in good health.

Disadvantages of IVF

1. The success of an IVF cycle is not guaranteed. It can require more than one cycle and not be effective.
2. The use of IVF may be linked to a number of adverse effects.
3. The issue of several births occurring simultaneously might also arise.
4. The pair may experience emotional stress as a result of using this strategy.
5. It is possible that the embryo will be implanted extrauterinely.
6. The approach is costly.
7. The premature birth of a low-weight infant is another possibility.
