Infertility is the inability of a Couple to achieve conception (pregnancy) after one full year of regular, unprotected, penetrative, vaginal sexual intercourse.
We urge couples who are unable to conceive after a year to consult a specialist.
It is however essential for couples who want conceive to have sexual intercourse regularly, at-least thrice weekly, especially around the time of the menstrual cycle when the woman ovulates.

(1)Fibroids

Fibroids are noncancerous growths in and around the uterus area. The growth of fibroids causes infertility by blocking the fallopian tubes and reducing the number of sperm that enters the uterus.
The presence of fibroids is usually diagnosed with a pelvic ultrasound; two in three women with fibroids don’t experience symptoms.
Some symptoms of fibroid growth include abdominal pain, painful periods and pain during sex, etc
Infertility caused by fibroid is usually resolved through surgery

(2) Low Sperm Count

Also known as sperm concentration, a normal sperm count is at least 15 million sperm cells per 1mL of semen. Sperm count less than this decreases the possibility of any sperm cells reaching the woman’s egg in the fallopian tubes from the vagina where they are ejaculated, and the condition is called oligospermia (low sperm count). Wearing of tight underwear (boxers) increases the temperature of the scrotum which can negatively affect sperm production, leading to low sperm count.
Sometimes, there may be no single sperm cell in the man’s ejaculate, a condition called azoospermia.

(3)Ovulation Disorders

An ovulation disorder is any condition that affects the normal ovulation process, which is necessary in order to conceive.
Most women ovulate every 21 to 35 days. This is when there is no ovulation at all (an ovulation) or the ovulation cycle is more than 35 days (oligo-ovulation). Medical therapy is often required for ovulation disorders.
