Human reproduction is any form of sexual reproduction resulting in human fertilization. It typically involves sexual intercourse between a man and a woman. During sexual intercourse, the interaction between the male and female reproductive systems results in fertilization of the woman's ovum by the man's sperm.

Unit 4, Lesson 4.5 - Sexual Reproduction in Animals
Lesson Outline:
1. Internal and External Fertilization
2. Internal and External Development
3. Sexual Reproduction Among Some Animals
4. Sexual vs. Asexual Reproduction
he reproductive system is a collection of internal and external organs — in both males and females — that work together for the purpose of procreating, according to the Cleveland Clinic. Due to its vital role in the survival of the species, many scientists argue that the reproductive system is among the most important systems in the entire body.
permatogenesis and oogenesis are the processes of formation of male and female gametes. Spermatogenesis leads to the formation of sperms, whereas oogenesis helps in the formation of ova. The fertilization of sperm and ova leads to the formation of a zygote which further develops into an embryo
This is entirely based on "REPRODUCTION", What is its process, How does it takes place..why does it takes place..
Topics Included are:
1.Reproduction
2.Human Male Reproductive System
3.Human Female Reproductive System
In part II-Other topics are covered in short

The reproductive tissues of male and female humans develop similarly in utero until about the seventh week of gestation when a low level of the hormone testosterone is released from the gonads of the developing male. Testosterone causes the primitive gonads to differentiate into male sexual organs. When testosterone is absent, the primitive gonads develop into ovaries. Tissues that produce a penis in males produce a clitoris in females. The tissue that will become the scrotum in a male becomes the labia in a female. Thus the male and female anatomies arise from a divergence in the development of what were once common embryonic structures.

Structure and functions of the female reproductive system
Process of menstrual cycle, reproduction and menopause
Structure and functions of breasts
Structure and functions of the male reproductive system
Reproductive health
Reproductive system:
The organs involved in producing offspring (a person's child or children).
In women, this system includes the ovaries, the fallopian tubes, the uterus, and the vagina.
In men, it includes the prostate, the testes, and the penis.
The female reproductive system
The female reproductive system plays many vital functions that ensure the continuation of the human race
Located in the pelvic cavity
Parts:
It consist of
External genitalia
Internal genitalia
External genitalia:
Labia minora
Labia majora
Clitoris
Vaginal orifice
Internal genitalia:
Ovaries
Fallopian tubes
Uterus
Vagina
Vagina:
A muscular tube, that extends from the cervix of the uterus to the outside of the body.
During intercourse, the vagina receives the male’s penis and semen.
Birth canal that the baby passes through in a normal delivery.
Ovaries:
Small almond-shaped glands that produce ova and the female sex hormones located on both sides of the uterus within the pelvic cavity.
In charge of ovulation and producing the female sex hormones.
The hormones are responsible for getting the lining of the uterus prepared for a fertilized ovum
Uterus:
Hollow organ (also called womb)
Fetus (unborn baby) develops and grows.
Contractions to the walls propels the baby during delivery through the birth canal in a normal delivery
Parts: fundus, body & cervix
The fundus is the broad curved upper area in which the fallopian tubes connect to the uterus;
The body, the main part of the uterus,
The cervix, extends downward and opens into the vagina.
Uterus has 3 layers:
The endometrium is the inner layer
The myometrium is the middle layer
The perimetrium is the outer layer
Function of uterus:
The uterus receives a fertilized egg and protects the fetus (baby) while it grows and develops.
The uterus contracts to push the baby out of the body during birth.
Every month, except when a woman is pregnant, the lining of the uterus grows and thickens in preparation for pregnancy.
If the woman doesn’t get pregnant, the lining is shed through the cervix into the vagina and out of the body. This is called menstruation.
The function of the female reproductive System:
The female reproductive system produces ova (the female reproductive cell)
Provides a location for fertilization
Growth of a fetus
Secretes female sex hormones
The breast produce milk to nourish the newborn.
Menstruation:
Menstruation, or period, is normal vaginal bleeding that occurs as part of a woman's monthly cycle.
Every month, your body prepares for pregnancy. If no pregnancy occurs, the uterus sheds its lining. The menstrual blood is partly blood and partly tissue from inside the uterus. It passes out of the body through the vagina.
Menstrual cycle:

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

4. The male sexual organs consist of the testis (plural: testes) and
penis.
The two testes lie outside the abdominal cavity in a special
sacs called the scrotum.
In this position, the testes are maintained at a temperature
about 2 C lower than the body temperature. This favours
sperm production.
Each testis is connected to the epididymis and sperm duct.
The two sperm duct lead to the urethra, which runs through the
penis to the exterior.
5. The urethra at different times carries either urine or sperms.
The penis contains many blood spaces which during copulation,
become filled with blood. This erects the penis, allowing it to
penetrate the female’s vagine.
The head of the penis, called the glans, is covered by the
foreskin. The foreskin is removed by an operation known as
circumcision.
Three glands open into the sperm ducts-the prostate gland,
Cowper’s glands and seminal vesicle.
6. Structure Function
Testis Produce sperm
Scrotum Holds the testes outside the body
Protects the testes
Penis Places sperm in the vagina during sexual intercourse
Epididymis Stores sperm
Sperm ducts Carry sperm from the testis to the urethra
Urethra Carries sperm and urine out of the body
Seminal vesicle Secretes fluid that provides nourishment to the sperms
Prostate gland Secretes fluid that neutralizes the acidity of urine and the
female vagina
Cowper’s gland Secretes a lubricating fluid that aids sperm movement
7. The role of sperms in reproduction
• The male gametes are the sperms.
• Each sperm consists of a head, a middle piece and a long tail.
• The role of the sperm is to swim towards the female gamete
(ovum) and fuses with it to form a zygote. The zygote will
develop into an adult individual.
8. Changes in the male during puberty
•Growth of hair on the face, chest in pubic region and armpits.
•Voice box (larynx) enlarges. The voice ‘breaks’ and becomes deeper.
• Body becomes more muscular.
• Chest becomes broader.
• Rapidly growth of long bones to increase height.
• The penis, scrotum and prostate become larger.
• Production of sperm by the testes.
•Certain mental and emotional changes, e.g. greater interest in
females.
9. The Female Reproductive System
• A female has a pair of ovaries attached to the lower part of the
abdomen.
• The Fallopian tubes( oviducts) are thin, muscular tubes.
• At one end , the fallopian tubes open out as funnel-shaped
structures close to the ovaries. At the opposite, they lead into the
uterus (womb)
• The pear-shaped uterus has thick, muscular wall.
• The uterus is connected to a muscular tube called the vagina.
12. • The cervix is a ring of muscles at the lower end of
the uterus where it join the vagina.
• The vagina opens to the outside through the vulva.
13. Structure Function
Ovary • Produce ovum(egg).
Fallopian tube • Carries ovum from ovary to uterus.
Uterus • Place where the embryo develops.
Cervix • Secrets mucus that enhances sperm
movement into the uterus.
• Prevents large foreign bodies from
entering uterus.
Vagina • Place where sperms are deposited.
• Birth canal.
14. The role of an ovum in reproduction
• The female gamete is the ovum.
• The ovum is larger than the sperm and it is spherical-shaped.
• The female fuses with the sperm to form a zygote during
fertilisation.
• The ovum stores some food in its cytoplasm.
The food is used to nourish the embryo which develops from the
zygote.
16. Changes in the female during puberty
• Growth of hair in the pubic region and armpits.
• Commencement of menstruation.
• Fat deposits on hips and thighs.
• Growth and development and breast.
17. Aspect Male
Female
gamete Notes
Size • Very
small
• Larger than the
sperm
• The human egg is 0.1 mm in
diameter while the sperm has a
width of 0.0025 mm at the widest
region of the sperm head.
Number • very large
numbers
• Very few • A healthy male produces about
300 million sperms every day. The
ovaries
each produce one egg on alternate
months.
Motility • Motile • Non-motile • Whip-like movements of the tail
propels the sperm towards the
ovum.
18. The Menstrual cycle
• The menstrual cycle is the repeated cycle of events which occur
every 28 days from puberty(when ovum production begins)to
menopause (when ovum production stops.
The menstrual cycle
19. •The main function of the menstrual cycle is to provide a
favourable environment in the uterus for the
development of the zygote.
•In most woman, the menstrual cycle varies from 24 to
34 days, averaging 28 days.
•The menstrual cycle starts when the female is about 12
years old and menopause occurs when the female is
about 45 years old.
20. •Menstruation is the discharge of the uterus lining and
blood through the vagina.
•The start of the menstrual cycle is considered as the
first day of menstruation (day 1) and ends the day
before the next menstruation starts.
21. Days in the cycle Events in the menstrual cycle
1 - 5 •Menstruation – discharged of
unfertilized egg, uterus lining and
blood.
6 - 13 •Rebuilding and thickening of the
uterus lining.
14 •Ovulation – release of ovum from
the ovary
15 - 25 •Continued thickening of the
uterus lining by increasing blood
supply and tissue.
26 - 28 •Uterus lining begins to break
down.
22. •The fertile period is the period around the time of
ovulation when a woman can become pregnant if she
has an intercourse. It is between day 11 and the day
17 of the cycle.
•The fertile period is calculated on the assumption
that sperms can survive up to three days in the
woman’s body while ovulation can occur any time
between day 13 and day 15 and the ovum lives for
about 36 hours after the ovulation.
23. Personal hygiene during menstruation
•Sanitary pads (sanitary towels) are worn as lining on the
underwear to absorb the menstrual discharge. This will prevent
the discharge from staining the clothes.
•The sanitary should be change about every four hours to
prevent unpleasant odour.
•Some women prefer to wear tampons which are inserted into
the vagina by means of an applicator.
24. •Tampons should not be used continually throughout
the menstrual period.
•Tampons should be changed every four hours during
the day and external sanitary pads should be worn at
night.
