Animal Reproduction

1
Animal Reproduction

• Monika Hajduk and Adrianna Pieta
• AP Biology Assessment Project

2
Asexual Reproduction

• Three methods
• Fission
• Budding
• Fragmentation
• Regeneration
• Has potential
• advantages

3
Sexual Reproduction

• Two types of fertilization
• Internal
• External
• Produce more species
• than survive to
• reproduce
• Evolved complex
• reproductive systems

Reproductive Anatomy of Male
5
Reproductive Anatomy of Female
6
Human Sexual Response

• Two types of physiological reactions
• Vasocongestion
• Myotonia
• The sexual
• response cycle
• can be divided
• into four phases
• Orgasm

7
Production of Reproductive Cells

• Spermatogenesis
• production of mature
• sperm cells in the male
• Oogenesis
• development of mature
• unfertilized ova in the female
• Three differences

8
Male and Female Pattern

• Male Pattern
• Female Pattern
• Menstrual Cycle
• Humans and other primates
• Estrogen Cycle
• Other mammals

9
Female Human Reproductive Cycle

• Menstrual Cycle
• Menstrual flow phase
• Proliferative phase
• Secretory phase
• Ovarian Cycle
• Follicular phase
• Ovulation
• Luteal Phase
• Menopause

10
From Conception to Birth

• Pregnancy preceded by conception
• Trimesters
• First Trimester- time of most radical change
• Second Trimester- uterus grows enough for
  pregnancy to become obvious
• Third Trimester- time of rapid growth of fetus
• Parturition

11
Contraception

• Different types of methods
• Prevent release of sex cells
• Keep sex cells apart
• Prevent implantation of embryo
• Abort embryo

12
Technology for Reproductive Problems

• Diagnosing genetic diseases
• Amniocentesis
• Chorionic villus sampling
• Sperm banks
• In vitro fertilization
