Infertility foundations

Reproductive health

Twelve months of trying (six after 35), then a work-up of the three things that must happen: an egg, a sperm, and a way for them to meet.

The work-up

QuestionTest
Is she ovulating?Cycle history; mid-luteal progesterone; TSH, prolactin; AMH and antral follicle count for ovarian reserve (a predictor of response to stimulation, not of natural fertility)
Is the sperm normal?Semen analysis (WHO reference limits); repeat if abnormal; refer for azoospermia
Are the tubes open and the cavity normal?Hysterosalpingogram (or hysterosalpingo-contrast sonography); saline sonography or hysteroscopy for the cavity; laparoscopy when endometriosis or adhesions are suspected
Anything else?Rubella immunity, cervical screening, folic acid, weight, smoking, alcohol, medications, genetic carrier screening where offered

Treatment by cause

  • Anovulation (PCOS): letrozole first line, clomiphene, gonadotrophins, laparoscopic ovarian drilling; weight management where relevant.
  • Hypothalamic amenorrhoea: address energy balance and stress; pulsatile GnRH or gonadotrophins.
  • Tubal factor: IVF; surgery for selected proximal or mild distal disease; salpingectomy for hydrosalpinx before IVF.
  • Male factor: lifestyle, treat varicocele in selected cases, intrauterine insemination, IVF with intracytoplasmic sperm injection, donor sperm.
  • Unexplained: expectant management in the young, then ovarian stimulation with intrauterine insemination, then IVF.
  • Fertility preservation before gonadotoxic treatment: oocyte or embryo cryopreservation; sperm banking.

Left hydrosalpinx

Transvaginal, left adnexa. An elongated, tubular, fluid-filled structure with incomplete septa (the folded tube).
