Study Notes
What is Fertility?
- Fertility refers to the natural ability of an individual or couple to conceive a child.
- It involves the functioning of the reproductive system, including the production of gametes (sperm and egg cells) and the ability of these cells to fertilize.
Factors Affecting Fertility
Female Fertility
- Age: fertility declines with age, especially after 35 years old
- Ovulation: regular ovulation is essential for fertility
- Hormonal balance: hormonal imbalances can affect ovulation and fertility
- Weight: being overweight or underweight can affect fertility
- Medical conditions: certain medical conditions, such as polycystic ovary syndrome (PCOS), can affect fertility
Male Fertility
- Age: fertility declines with age, but not as sharply as in women
- Sperm quality: low sperm count, abnormal sperm morphology, and poor sperm motility can affect fertility
- Hormonal balance: hormonal imbalances can affect sperm production
- Lifestyle factors: smoking, excessive alcohol consumption, and certain medications can affect fertility
Infertility
- Infertility is defined as the inability to conceive after one year of regular, unprotected sex
- Primary infertility: refers to individuals who have never conceived
- Secondary infertility: refers to individuals who have previously conceived but are unable to conceive again
Causes of Infertility
- Female factors: 40-50% of infertility cases
- Ovulation disorders (25-30%)
- Tubal damage or blockage (20-30%)
- Endometriosis (10-20%)
- Uterine or cervical abnormalities (5-10%)
- Male factors: 30-40% of infertility cases
- Low sperm count (30-40%)
- Abnormal sperm morphology (20-30%)
- Poor sperm motility (10-20%)
- Unexplained infertility: 10-20% of infertility cases
- Combined male and female factors: 10-20% of infertility cases
Fertility Treatments
- Medications: fertility drugs to stimulate ovulation or improve sperm quality
- Intrauterine insemination (IUI): placing sperm directly into the uterus
- In vitro fertilization (IVF): combining sperm and egg cells in a laboratory dish
- Assisted reproductive technology (ART): includes IVF, IUI, and other technologies to aid conception
Definition of Fertility
- Natural ability to conceive a child
- Involves reproductive system functions, including gamete production and fertilization ability
Factors Affecting Fertility
Female Fertility
- Age: Notable decline in fertility begins after age 35
- Ovulation: Regular ovulation is crucial for conception
- Hormonal Balance: Imbalances can disrupt ovulation and reduce fertility
- Weight: Both underweight and overweight conditions can impair fertility
- Medical Conditions: Disorders like polycystic ovary syndrome (PCOS) can negatively impact fertility
Male Fertility
- Age: Gradual decline in fertility with age, but less pronounced than in women
- Sperm Quality: Affects include low sperm count, abnormal morphology, and motility issues
- Hormonal Balance: Imbalances can limit sperm production
- Lifestyle Factors: Smoking, excessive drinking, and certain medications can decrease fertility
Infertility
- Defined as the inability to conceive after one year of regular, unprotected intercourse
- Primary Infertility: Individuals who have never conceived
- Secondary Infertility: Individuals who have conceived previously but cannot conceive again

-
Male Factors: Account for 30-40% of infertility cases

Fertility Treatments
- Medications: Fertility drugs used to induce ovulation or enhance sperm quality
- Intrauterine Insemination (IUI): Direct placement of sperm into the uterus
- In Vitro Fertilization (IVF): Fertilization occurs in a lab dish
- Assisted Reproductive Technology (ART): Encompasses IVF, IUI, and similar techniques to support conception
