PubHealth.info® (a subsidiary of PakMed) presents scientific information mainly based on abstracts of articles published on a variety of public health issues/topics, particularly encompassing population planning, disease prevention, maternal and child health, and communicable and non-communicable diseases (like HIV AIDS, malaria, etc) that are affecting a significant portion of population in developing and developed countries. Here you can find abstracts of articles published on a variety of public health topics under category "Contraception (Birth Control) and Family Planning". Contraception (birth control) is a regimen of one or more actions, devices, or medications followed in order to deliberately prevent or reduce the likelihood of a woman becoming pregnant or giving birth. Therefore contraception is the utilization of various and sundry surgical procedures, devices, practices, agents, or drugs with the intention of preventing conception or impregnation (pregnancy). Methods and intentions typically termed birth control may be considered a pivotal ingredient to family planning. Birth control is a controversial political and ethical issue in many cultures and religions, and although it is generally less controversial than abortion specifically.

ABSTRACT

The aim of this study was to investigate whether the day of ovulation and the duration of a pretreatment cycle were

related to the degree of follicular growth during subsequent contraceptive treatment. This randomized, open-label

study was performed in 40 healthy female volunteers, who were randomized by a computer-generated list after

stratification for the ovulation day in a pretreatment cycle. They received two cycles of NuvaRing (21 subjects) or a

combined oral contraceptive (COC) containing 30µg ethinylestradiol and 150µg levonorgestrel (19 subjects).

Follicular diameter and serum hormone concentrations (FSH, LH, 17ß-estradiol, progesterone) were measured every

third day. Data from treatment day 20 onwards were used for analysis. In the NuvaRing users, subjects with short

cycles and early ovulations in the pretreatment cycle developed larger follicles during treatment than subjects with

longer cycles and late ovulations. In the COC users, subjects with early ovulations in the pretreatment cycle

developed larger follicles during treatment. The degree of follicular growth during treatment with a combined

hormonal contraceptive is influenced by the duration of the pretreatment cycle and particularly by the duration of the

follicular phase. (PubHealth.info Document ID: CONT1T 563-06)
