Physiological infertility
“Shortly” after menarche (first menstrual bleeding) After newborn delivery and during breastfeeding“Shortly” before menopauseThe highest chance to become pregnant – sex 1 or 2 days before ovulation (28% - 30%)Fecundability 20% per cycle
![Page 4: Family planning Clinic of Reproduction and Gynecology PAM.](https://reader034.fdocuments.net/reader034/viewer/2022042821/56649d1f5503460f949f2cda/html5/thumbnails/4.jpg)
Factors affecting negative effect of breastfeeding on fertility
Time lapsed from delivery Duration and frequency of breastfeedingNutrition Social and cultural determinantsTo sum up – breastfeeding does not protect against unwanted pregnancy

Action of oral contraceptives
Inhibition of GnRH release Inhibition of ovulationChanges in the fallopian tubes – motility, epithelial structure, oviductal fluid – impaired transport of sperm, oocytes and embryosChanges in the endometrium – endometrium becomes thin – impaired implantation Changes in the cervix – mucous becomes thick – sperm hardly penetrates
OC

Barrier methods
For males:Condom
For women:DiaphragmCervical capVagninal foam, cream, suppositories (contain nonoxynol-9 – kills and immobilizes sperm)

Condom
PROTECTION against STDs (AIDS included)Easy to useCheapAlmost no side-effects (minor local allergic reactions to latex)Prevention malignancies of the cervix

Disadvantages of condoms
Impaired sexual satisfactionAllergyNot comfortable in use
![Page 21: Family planning Clinic of Reproduction and Gynecology PAM.](https://reader034.fdocuments.net/reader034/viewer/2022042821/56649d1f5503460f949f2cda/html5/thumbnails/21.jpg)
Physiological bases for periodic abstinence
The first probable day of expected ovulation14 – 2 = 12 day
The last possible day of expected ovulation14 + 2 = 16 day
Sperm survival (48 h) 12 – 2 = 10 day
Oocyte capability of being fertilized (24 h) 16 + 1 = 17 day
Fertile span of time 10 - 17 day of the cycleThe “tuned” method is called SYMPTOTHERMAL (+
BBT, cervical mucous)
