Infertility: Understanding the Journey to Parenthood
Infertility is more common than many people realize, affecting millions of individuals and couples worldwide. It is not solely a women’s health issue—male and female factors contribute almost equally. Fortunately, advances in reproductive medicine, healthier lifestyle choices, and early diagnosis have made parenthood possible for many families. At Pulse by Anubhav, we believe that accurate information is the first step toward informed decisions and hope.
What is Infertility?
Infertility is the inability to achieve pregnancy despite having regular, unprotected sexual intercourse for a specific period:
- Women younger than 35 years: Unable to conceive after 12 months of trying.
- Women aged 35 years or older: Unable to conceive after 6 months of trying.
Pregnancy depends on both partners. Research shows that male-related factors contribute to nearly half of infertility cases, either alone or combined with female factors.
Global Facts About Infertility
- Around 1 in 6 adults experience infertility during their lifetime.
- Infertility affects people of every age, race, and socioeconomic background.
- Millions of couples face emotional and social challenges due to misconceptions surrounding infertility.
- Both primary infertility and secondary infertility are common worldwide.
Types of Infertility
Primary Infertility
Primary infertility refers to couples who have never achieved pregnancy despite regular, unprotected intercourse for the recommended duration.
Secondary Infertility
Secondary infertility occurs when a couple has difficulty conceiving after previously experiencing one or more pregnancies, regardless of the pregnancy outcome.
How Pregnancy Normally Happens
For a healthy pregnancy to occur, several biological processes must work together:
- The ovary releases a healthy egg (ovulation).
- Healthy sperm travel successfully to the egg.
- Fertilization occurs inside the fallopian tube.
- The fertilized embryo moves into the uterus.
- The embryo implants into a healthy uterine lining.
A problem at any stage can reduce fertility and make conception difficult.

Causes of Female Infertility
Ovulation Disorders
Ovulation disorders are among the most common causes of female infertility.
Common conditions include:
- Polycystic Ovary Syndrome (PCOS)
- Thyroid disorders
- Elevated prolactin levels
- Premature ovarian insufficiency
- Hypothalamic dysfunction caused by stress, excessive exercise, or significant weight loss
Common symptoms include:
- Irregular menstrual cycles
- Missed periods
- Very long cycles
- Absence of menstruation
Fallopian Tube Disorders
Healthy fallopian tubes are essential because fertilization usually occurs within them.
Damage or blockage may result from:
- Pelvic inflammatory disease (PID)
- Sexually transmitted infections (STIs)
- Endometriosis
- Previous ectopic pregnancy
- Prior abdominal or pelvic surgery
Endometriosis
Endometriosis develops when tissue similar to the uterine lining grows outside the uterus.
It may cause:
- Severe menstrual pain
- Chronic pelvic pain
- Pain during intercourse
- Reduced fertility due to inflammation and scar tissue
Uterine Conditions
A healthy uterus is necessary for embryo implantation.
Problems may include:
- Uterine fibroids
- Endometrial polyps
- Congenital uterine abnormalities
- Intrauterine adhesions (Asherman syndrome)
Age-Related Fertility Decline
Female fertility naturally decreases with age, especially after 35 years, because both egg quantity and egg quality gradually decline. This also increases the risk of miscarriage and chromosomal abnormalities.
Causes of Male Infertility
Male infertility accounts for nearly half of all infertility cases.
Common causes include:
- Low sperm count
- Poor sperm motility
- Abnormal sperm morphology
- Varicocele
- Genetic disorders
- Hormonal imbalance
- Infections
- Smoking
- Excessive alcohol consumption
- Drug abuse
- Heat exposure
- Obesity
Lifestyle Factors That Can Affect Fertility
Daily habits play a significant role in reproductive health.
Risk factors include:
- Smoking
- Heavy alcohol intake
- Recreational drug use
- Obesity or being underweight
- Poor nutrition
- Lack of quality sleep
- Chronic stress
- Excess caffeine intake
- Exposure to pesticides, radiation, and environmental toxins
Symptoms of Infertility
Symptoms in Women
Possible warning signs include:
- Irregular periods
- Heavy menstrual bleeding
- Painful periods
- No menstrual periods
- Pelvic pain
- Pain during sexual intercourse
Symptoms in Men
Possible symptoms include:
- Erectile dysfunction
- Ejaculation problems
- Reduced sexual desire
- Testicular pain or swelling
- Small testes
- Reduced facial or body hair due to hormonal disorders
Important: Many individuals with infertility may experience no noticeable symptoms, making timely medical evaluation essential.
How Doctors Diagnose Infertility
Female Fertility Evaluation

Treatment Options for Infertility
Treatment depends entirely on the underlying cause and may involve one or more approaches.
Lifestyle Modification
Doctors often recommend:
- Achieving a healthy body weight
- Eating a balanced diet
- Regular physical activity
- Stress management
- Quitting smoking
- Limiting alcohol consumption
- Avoiding recreational drugs
Medications
Medicines are commonly prescribed for:
- Ovulation disorders

There is no single medicine that treats every case of infertility. Doctors prescribe fertility medicines only after identifying the underlying cause through blood tests, ultrasound, semen analysis, or other fertility investigations. The treatment plan differs for men and women.
| Medicine (Generic) | Main Use | How It Works | Example Brand* | Monitoring |
|---|---|---|---|---|
| Clomiphene Citrate | Ovulation disorders (especially PCOS) | Stimulates hormones that help the ovary release a mature egg. | Clomid®, Siphene® | Ultrasound follicle monitoring |
| Letrozole | Ovulation induction | Reduces estrogen temporarily, encouraging the brain to release more FSH and LH. | Femara®, Letoval® | Ultrasound and ovulation tracking |
| Human Menopausal Gonadotropin (hMG) | Stimulates multiple follicles | Provides FSH and LH hormones to support egg development. | Menopur® | Ultrasound + blood hormone tests |
| Recombinant FSH | IVF and IUI cycles | Directly stimulates ovarian follicles to mature. | Gonal-f®, Puregon® | Close fertility specialist supervision |
| hCG Injection | Triggers ovulation | Helps release the mature egg at the correct time. | Ovitrelle®, Pregnyl® | Timed intercourse, IUI, or IVF |
| Metformin | PCOS with insulin resistance | Improves insulin sensitivity and may restore regular ovulation. | Glycomet®, Glucophage® | Blood sugar monitoring when required |
| Cabergoline / Bromocriptine | High prolactin levels | Reduces prolactin hormone and restores ovulation. | Dostinex®, Parlodel® | Periodic prolactin blood tests |
| Levothyroxine | Hypothyroidism | Corrects thyroid hormone deficiency that may affect fertility. | Eltroxin®, Thyronorm® | Regular TSH monitoring |
⚠️ Important Safety Information
- These medicines should only be taken after evaluation by a fertility specialist.
- The dosage varies depending on age, hormone levels, ovarian reserve, and fertility diagnosis.
- Self-medication can lead to ovarian hyperstimulation, multiple pregnancy, or treatment failure.
- Brand names may differ depending on your country and healthcare provider.
- Always purchase prescription medicines from licensed pharmacies with a valid prescription.
Surgical Treatment
Surgery may help treat:
- Fibroids
- Polyps
- Endometriosis
- Selected cases of blocked fallopian tubes
- Varicocele
Intrauterine Insemination (IUI)
IUI involves placing specially prepared healthy sperm directly into the uterus around ovulation to improve the likelihood of fertilization.
In Vitro Fertilization (IVF)
During IVF, eggs are collected from the ovaries, fertilized with sperm in a laboratory, and the healthiest embryo is transferred into the uterus.
Intracytoplasmic Sperm Injection (ICSI)
ICSI involves injecting a single healthy sperm directly into an egg and is particularly beneficial in severe male infertility.
Fertility Preservation
People planning cancer treatment or delaying pregnancy may consider:
- Egg freezing
- Sperm freezing
- Embryo freezing
Certain medicines can affect fertility in men or women, especially when used for a long time or in high doses. However, this does not mean everyone taking these medicines will become infertile. The effect depends on your age, overall health, dosage, and the duration of treatment. Never stop a prescribed medicine without consulting your doctor.
| Medicine Category | How It May Affect Fertility | Examples |
|---|---|---|
| Chemotherapy Drugs | May damage eggs or sperm and sometimes reduce fertility permanently depending on the drug and dose. | Cyclophosphamide, Cisplatin |
| Anabolic Steroids | Can reduce testosterone production, lower sperm count, and shrink the testicles. | Testosterone injections, Bodybuilding steroids |
| Cancer Hormone Therapy | May temporarily or permanently affect reproductive hormone production. | Tamoxifen, GnRH medicines |
| Some Antidepressants | May reduce sexual desire or affect ejaculation in some individuals. | SSRIs (selected patients) |
| Certain Antipsychotics | Can increase prolactin levels, which may interfere with ovulation or sperm production. | Risperidone, Haloperidol |
| Long-term Opioids | May reduce reproductive hormones and decrease fertility over time. | Morphine, Oxycodone |
| NSAIDs (Long-term Use) | In some women, prolonged use may interfere with ovulation. | Ibuprofen, Naproxen |
Important Note
Most people who take these medicines do not become infertile. Many fertility-related side effects improve after treatment is stopped, while others may require medical evaluation. If you are planning a pregnancy, discuss your medications with your healthcare provider before making any changes.
