Intracytoplasmic Sperm Injection (ICSI): Process and Use
Intracytoplasmic sperm injection places one sperm directly into an egg during IVF and may help when sperm count, movement, or fertilizing ability is severely reduced.
Hypogonadism: Types, Symptoms, Causes, and Treatment
Hypogonadism occurs when the ovaries or testes produce insufficient sex hormones or reproductive cells, affecting puberty, fertility, bones, and sexual health.
Azoospermia: Types, Causes, Diagnosis, and Fertility
Azoospermia means no sperm are detected in ejaculated semen because of blockage or impaired sperm production, although treatment may sometimes help.
Oligospermia: Causes, Testing, Treatment, and Fertility
Oligospermia, or oligozoospermia, means semen contains a lower-than-expected sperm concentration, which may reduce fertility but does not rule out pregnancy.
Asthenozoospermia: Causes, Testing, and Fertility
Asthenozoospermia means that sperm have reduced movement, which may make fertilization more difficult but does not always prevent natural pregnancy.
Teratozoospermia: Causes, Diagnosis, and Fertility
Teratozoospermia means that a lower-than-expected proportion of sperm have typical shapes, which may affect fertilization but does not always prevent pregnancy.
Primary Ovarian Insufficiency: Symptoms, Causes, and Care
Primary ovarian insufficiency causes reduced or unpredictable ovarian function before age 40 and may affect periods, estrogen, fertility, bones, and sexual comfort.
Luteinizing Hormone: Function, LH Surge, and Testing
Luteinizing hormone is a pituitary hormone that triggers ovulation, supports progesterone production, and stimulates testosterone production in the testes.
Estradiol: Function, Levels, Testing, and Sexual Health
Estradiol is a major estrogen hormone involved in menstrual cycles, ovulation, fertility, bone health, sexual development, and genital tissue health.
Progesterone: Function, Testing, Pregnancy, and Fertility
Progesterone is a reproductive hormone that rises after ovulation, prepares the uterine lining, supports pregnancy, and influences menstruation and fertility.
