Infertility basics

fertility is the probability of conception which decreases over time

Fertility basics : MFR and CRP

Fertility basics : MFR and CRP

Fundamental are MFR (monthly fecundity rate ) and CPR (cumulative pregnancy rate

  • MFR : is the probability of conception in one month
  • CPR : is the cumulative probability of conception over the next 6 or 12 months

Since the most fertile couples will be faster pregnant the remaining population will be progressively less fertile ie a lower MFR. After 1 year of infertility the MFR has dropped to 10%/month.

When to start a fertility investigation

Fertility basics : MFR and CRP

Fertility basics : MFR and CRP

CPR is the probability of becoming pregnant within 6months or 1 year

  • after 1 year of infertility still 80% of couples will get pregnant spontaneously over the following years
  • after 2 years of infertility the cumulative pregnancy rate drops to 50%
  • after 5 years of infertility : less than 20% will get pregnant spontaneously
 

The investigation for infertility

The investigations for infertility estimates the probability of conception ( MFR and CPR) .
Investigation of

  • ovulation
  • transport of the oocyte
  • implantation
  • cervical function
  • sperm quality
Practically

  • basal body temperature  ; presence of endometriosis
  • HSG, laparoscopy
  • Hysteroscopy , endometrial biopsy
  • post coital test
  • sperm test

 

Always a diagnostic laparoscopy ?

Adhesion of the fibria to the wall : this causes infertility and is missed without a laparoscopy

 
Reproductive surgery and IVF are complementary

Reproductive surgery and IVF are complementary

  • During laparoscopy endometriosis, adhesions, uterine fibroids, uterine septa, hydrosalpinx etc can be taken care of, if the surgeon has the skills
  • Without a laparoscopy many factors as adhesions or endometriosis cannot be diagnosed
  • IVF without a diagnosis results in a lower CPR
  • IVF with severe endometriosis results in a frozen pelvis
  • The decision to perform a diagnostic laparoscopy is caught between
    • an early and systematic laparoscopy and a complete diagnosis and a treatment of mechanical problems
    • the risk that laparoscopy reveals a normal pelvis and was not useful
    • missing a a treatable mechanical problem risks to loose time exist
 

The problems of infertility treatment

Many infertility clinics have become IVF clinics

Reproductive surgery anno 2017

  • the infertility basics are considered less important since IVF is a solution for all
  • the quality of reproductive surgery had decreased over the years
  • up to the point of starting IVF without a diagnosis or without a laparoscopy

infertility, endometriosis, treatment, therapy

The medico-industrial complex

adhesions, infertility

LUF : A corpus luteum without an ovulation stigma

problems as LUF eventually as a consequence of endometriosis, transport problems as adhesions or tubal mucosal damage, implantation problems as adenomyosis, cervical problems as  immunologic infertility and most of the male factor problems. The availability and the relatively high success rates of IVF moreover have lead to an overuse of IVF while infertility surgery has become disregarded.

2018 Reproductive surgery

Fertility surgery should be done during the diagnostic laparoscopy

Ideally this should be done but practically ………..

the absence of a CO2 laser : the quality of endometriosis surgery is less, and the intervention takes a longer time with more adhesions .

a ‘slow or less experienced surgeon ‘ has more adhesions because surgery takes longer and because of more surgical trauma

Surgery beyond the level mastered : causes damage (destruction of the ovary) and incomplete excision of endometriosis or unnecessary bowel resections and thus IVF.
