  1. INFERTILITY

  2. DEFINITION • Infertility is defined as failure to conceive within one or more years of regular un protected coitus.

  3. TYPES • Primary infertility • Secondary infertility

  4. INCIDENCE • 80% achieve conception within one year if they desire • 10% by the end of second year. • 10% remain infertile by the end of second year.

  5. FACTORS RESPONSIBLE FOR FERTILITY • Healthy spermatozoa should deposited high in the vagina. • Spermatozoa should undergo changes and acquire motility. • The motile spermatozoa should ascend through the cervix into the uterine cavity and fallopian tube. • There should be ovulation. • The fallopian tubes should be patent and the oocyte should be picked up by the fimbriated end of the tube

  6. The spermatozoa should fertilize the oocyte at the ampulla of the tube. • The embryo should reach the uterine cavity after 3-4 days of fertilization. • The endometrium should be prepared for implantation and corpus luteum should function adequately.

  7. CAUSES OF INFERTILITYFACTORS IN MEN • Abnormalities of the sperm. • Abnormal erections • Abnormal ejaculation • Abnormalities of seminal fluid.

  8. FACTORS IN WOMEN • Disorders of ovulation • Abnormalities of fallopian tube. • Abnormalities of the cervix or uterus

  9. REPEATED PREGNANCY LOSS • Abnormalities of fetal chromosomes • Abnormalities of the cervix or uterus. • Endocrine abnormalities. • Immunologic factors • Environmental factors. • Infection

  10. SPECIFIC INVESTIGATIONSMALE 1. Semen analysis 2. Serum FSH, LH, testosterone, prolactin and TSH 3. Fructose content in seminal fluid 4. Testicular biopsy 5. Karyotype analysis 6. Immunological tests 7. Trans rectal ultra sound (TRUS) 8. Vasogram 9.Presence of pus cells

  11. FEMALE • Basal body temperature • Cervical mucus study • Hormone estimation • Serum progesterone • Serum LH • Serum estradiol 4. Endometrial biopsy 5. Ovum transport: investigation of tube patency • Laparoscopy • Hysterosalpingography

  12. THERAPIES TO FACILITATE PREGNANCY • Stimulation of ovulation • Clomiphene citrate (clomid) • Human chorionic gonadotrophin (HCG) • Human menopausal gonadotrophin (HMG) • Bromocriptine (parlodel) 2.Surgical procedures 3. Egg donation 4. Surrogate parenting

  13. 5. Assisted reproductive technology • Artificial insemination by husband (AIH) • Artificial insemination by donor (AID/DI) • Invitro fertilization/ embryo transfer (IVF/ET) • Gamete intrafallopian transfer (GIFT) • Zygote intrafallopian transfer (ZIFT) • Intracytoplasmic sperm injection (ICSI)
