- What IVF is and a brief history of its development
- Why it is used, typically for issues like damaged fallopian tubes or male factor infertility
- Benefits like helping more people have families but also concerns like health risks of multiple pregnancies
- The social impacts, including lack of regulation for surrogacy which led to legal dilemmas, and debates over stem cell research and "creating immortality"

The Assisted Reproductive Techniques - ART (IVF, IUI, ZIFT, GIFT, ICSI etc.)Muhammad Anas Shamsi
Assisted reproductive technology (ART) is used to treat infertility. It includes fertility treatments that handle both a woman's egg and a man's sperm. It works by removing eggs from a woman's body. The eggs are then mixed with sperm to make embryos. The embryos are then put back in the woman's body. In vitro fertilization (IVF) is the most common and effective type of ART.

Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

What is In Vitro
Fertilization (IVF)?
IVF is the procedure of
joining a man’s sperm and
a woman’s egg together in
a petri dish. The
fertilization process occurs
over a four-day period, at
which time the new embryo
is transplanted into the
woman uterus. P.130
5. +
Brief History of In-Vitro Fertilization
Early IVF experiments began as early at 1878 with
the use of rabbits
Robert Edwards and Patrick Steptoe, a
gynecologist, began IVF in humans in Britain in the
1970s.
In 1977, the two, successfully implanted Lesley
Brown with a fertilized egg.
On July 25, 1978 the first test tube baby was born,
Louise Brown

In-Vitro Fertilization is in most
cases preformed in the
following situations:
• Damaged fallopian tubes
• Ovulation disorders
• Cervical factors
• Male factors, such as low
sperm count or poor-quality
sperm
• Surogacie
Why In Vitro
Fertilization?
7. +
Who is Using In Vitro
Fertilization?
1.2 million American women in 2002 considered
IVF within the last year
6 million American women have undergone
infertility treatment in their life
IVF treatment represents 5% of over infertility
treatments in America
Fertility drugs, surgery, and artificial
insemination are usually attempted before IVF
Most women using IVF treatment suffer from
blocked or damaged fallopian tubes
8. +
Benefits of In Vitro Fertilization
Creates more families
Infertile couples now have a greater chance to
become pregnant
Scientists are able to study fertilization and
early embryonic development in an
environment outside a woman’s body. Giving a
greater understanding to the reasons behind
birth defects
9. Concerns with In-Vitro
Fertilization
Health Risks:
Health risks a multiple pregnancy can bring both woman and babies
The IVF procedure can cause ectopic pregnancy
Ovarian hyperstimulation syndrome is a side effect of the procedure
Babies born through IVF are 30% more likely to be born with birth
defects
+
Social Issues:
An unnatural pregnancy is viewed as wrong or against the will of god
The cost associated with a multiple child birth is more that double of
a single child birth.
The age a woman becomes pregnant and give birth can effect the
child social/sociological life long term
10. + A major social issue involved with In-
Vitro fertilization is the lack of regulation
The Social Impact of
in regard to the process of surrogates.
In-Vitro Fertilization
As read in our text in the 1980’s a
surrogate mother tried to keep the baby
she had carried through pregnancy.
This created a dilemma because of the
lack of legislation.
Ultimately the judge sided with couple,
which hired the surrogate.
This grey area created through the
technology of in-vitro does cause a
dilemma just because of the emotions
associated with child birth.
11. Another social issue is associated with
+
in-vitro is the possibility of stem cells.
The Social Impact of
In the past decade stem cells have
In-Vitro Fertilization
created a great deal of discussion in
regard to the purpose and possibilities
attainable through this technology.
The whole process of in-vitro creates the
possibility for stem cell research.
The most controversial aspect of stem
cell’s is that they can reproduce almost
any aspect of the human body, which
can be frightening for most due to the
aspect of possibly creating immortality.
This idea of using technology to create
immortality has been debated for many
years, in my opinion it goes against
human nature due to a lack of
progression.
This is why in-vitro has to be closely
monitored for future success.
