Question

Analyze each of the following scientific reports, explaining how the pattern of the method of agreement is manifested by each. Discuss, in each case, the limitations of the method of agreement as applied to that quest for a causal connection.

Medical researchers have concluded not only that the timing of sexual intercourse in relation to ovulation strongly influences the chance of conception, but that conception occurs only when intercourse takes place during a specifiable period in the menstrual cycle. The researchers summarized their findings thus:

We recruited 221 healthy women who were planning to become pregnant. At the same time the women stopped using birth control methods, they began collecting daily urine specimens and keeping daily records of whether they had sexual intercourse. We measured estrogen and progesterone metabolites in urine to estimate the day of ovulation. In a total of 625 menstrual cycles for which the dates of ovulation could be estimated, 192 pregnancies were initiated. . . . Two-thirds (n = 129) ended in live births. Conception occurred only when intercourse took place during a six-day period that ended on the estimated day of ovulation. The probability of conception ranged from 0.10 when intercourse occurred five days before ovulation to 0.33 when it occurred on the day of ovulation itself. Conclusion: Among healthy women trying to conceive, nearly all pregnancies can be attributed to intercourse during a six-day period ending on the day of ovulation.

Answer 1

Meaning of Ovulation- it is the discharge of ova or ovules from the ovary

Meaning of Menstruation- the process in a woman of discharging blood and other matrial from th e lining of the uterus at intervals of about one lunar month from puberty until the menopause ,except during pregnancy

Meaning of conception- the action of conceiving a child or of one being conceived

Ovulation is a phase in the menstral cycle.It occurs about day 14 of a 2 day cycle. At about 14 day 14 in the menctural cycle ,a sudden surge in luteinsing hormome causes the ovary to release its egg. the eg begins its fiveday travel through a narrow , hollow structure called the fallopian tube to the uterus.As the egg is travelling through the fallopian tube , the level of progesterone , another hormone rises which helps to prepare the uterine lining for pregnancy

Conception occurs when a sperm cell from a ferilt man swims up through the and into the uterus of a woman and joins with the womans egg celel as it travel s down one of the fallopian tubes from the ovary to the uterus.

Getting pregnant after ovulation is possible, but is limited to the 12-24 hous after your egg has been released .cervical mucus helps sperm live upto 5 days in a wpmans body and it takes around 6 hours for active sperms to reach the falopian tube. there are actually only about 6 days during our cycle when one can become pregnant. the ifve days before ovulation and day of ovulation .And while some women may get pregnant right way , for others the time to pregnancy may take a littlie longer

thus as scientific researcher explains there is a possibility of conception during ovulation period.
