Answer:
Bacterial; viral
Explanation:
Sexually transmitted diseases can be caused by bacteria, viruses, and protozoa. Sexually transmitted diseases caused by protozoa can easily be treated. Bacterial STD can be treated with antibiotics during the initial phase of the disease so bacterial STDs are curable.
Viral STDs are not curable but their symptoms can be managed by taking medication. Viral STDs are not curable because they incorporate their DNA into the host genome and can remain in the latent phase in their host cell.
Contraceptive methods are birth control and planning strategies. Withdrawal before ejaculation is the least likely method that prevents fertilization. Thus, option D is correct.
<h3>What are contraceptives?</h3>
Contraceptives are the birth control methods used by males and females to prevent the fertilization of sperm and eggs. Diaphragm, vasectomy, IUD, condoms, withdrawal before ejaculation, etc. are some of the contraceptive methods.
The diaphragm is the barrier method used by females to prevent sperm entry inside the vagina. Similarly, IUD is inserted inside the uterus of the female to prevent fertilization.
Vasectomy is the irreversible contraceptive method in which the vas deferens of the male reproductive system are tied. The withdrawal before ejaculation is least likely to prevent fertilization but is not a reliable method.
Therefore, withdrawal before ejaculation is not an effective contraceptive method.
